4 References When designing your smoke control system, you must read and become familiar with the following documents, codes, and standards, as applicable: National Fire Protection Association (NFPA) 92A Recommended Practice for Smoke Control Systems American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) publication entitled Design of Smoke Control Systems for Buildings NFPA 70 National Electrical Code NFPA 72 National Fire Alarm Code NFPA 101 Life Safety Code NFPA 90A Standard for the Installation of Air-Conditioning and Ventilating Systems NFPA 92B Guide for Smoke Management Systems in Malls, Atria, and Large Areas International Code Council (ICC) which includes: - Building Officials and Code Administrators International (BOCA) model code - International Conference of Building Officials (ICBO) model code - Southern Building Code Congress International (SBCCI) regulations UL 864 Standard for Control Units and Accessories for Fire Alarm Systems Smoke Control Design Objectives The design objectives of a smoke control system are to: maintain a safe and smoke free environment in emergency exit routes and areas of refuge during the evacuation of a facility contain the smoke within or remove the smoke from the fire area and minimize its migration to other areas of the facility provide for conditions outside the fire area that are conducive to the performance of emergency operations such as evacuation, fire control, and rescue protect life and minimize property loss 4 Metasys System Extended Architecture Smoke Control System Technical Bulletin

5 Smoke Control Requirements This section contains the Metasys system extended architecture configuration requirements for a UL 864 UUKL Listed Smoke Control system. You must follow these requirements to comply with the UL Listing. Assume any reference to UL Listing to mean UL 864 UUKL Listing, unless otherwise stated. See the UL Listed Devices for Smoke Control section for the Listed components. Johnson Controls Smoke Control Listing is valid only with Metasys system extended architecture components UL Listed for smoke control. Agency Requirements The NFPA and UL have published documents, which include provisions for the control of smoke. These documents are as follows: NFPA 92A Recommended Practice for Smoke Control Systems NFPA 90A Standard for the Installation of Air-Conditioning and Ventilating Systems UL 864 Standard for Control Units and Accessories for Fire Alarm Systems UL 555S Standard Smoke Dampers NFPA 72 National Fire Alarm Code NFPA 70 National Electrical Code NFPA 101 Life Safety Code In Canada, refer to the following documents: ULC/ORD-C539 Fire Alarm Devices, Single and Multiple Station, Mechanically Operated ULC/ORD-C2043 Fire Test for Smoke and Visible Heat Release for Discrete Products and Their Accessories Installed in Air-Handling Spaces You can purchase current versions of NFPA documents by calling the National Fire Protection Association at and current versions of UL documents by calling UL at As with other types of systems designed and installed to protect life and property, the responsibility for approving equipment, installations and procedures lies with the local Authority Having Jurisdiction (AHJ). The phrase Authority Having Jurisdiction refers to the agency or individual responsible for approving equipment, an installation, or a procedure, and giving permission to occupy a building. In most municipalities, that responsibility lies with the fire chief, fire marshal, electrical inspector, or others having statutory authority. Become familiar with the building codes of your community as its requirements may differ from those of the NFPA. Metasys System Extended Architecture Smoke Control System Technical Bulletin 5

6 Other entities, such as an insurance carrier or hospital accreditation organization may have influence and/or right of approval of the smoke control system configuration. Smoke Control System Wiring Requirements per UL 864 UUKL Complete all field wiring in compliance with this technical bulletin and the Metasys System Extended Architecture Smoke Control Wiring Technical Bulletin (LIT ). Component Requirements You must have the following components to configure and assemble a Metasys System Extended Architecture network to comply with UL 864 UUKL Smoke Control Listing: Smoke Control Network Automation Engine (NAE) Use the Smoke Control NAE, MS-NAE5510-0U, to interface all input and output smoke control points. The internal modem and LAN port are not available on the smoke control NAE. Place the Smoke Control NAE in a locked enclosure. Fire Fighters Smoke Control Station (FSCS) Follow these guidelines: Use a UL 864 UUKL Listed FSCS to provide manual control of smoke control systems. You must use the UL Listed annunciator panel made by Automation Displays, Inc. See the FSCS Requirements section for ADI contact information. Provide positive indication on the FSCS of the operation of all smoke control equipment, for example, that the damper reaches its intended position. Configure each Binary Output (BO) object used for pressurization and exhaust control outputs with positive feedback, which monitors the associated controlled equipment status. Typically, smoke control dampers provide a pair of feedback binary inputs for the two damper end switches, full open and full closed. For fans used for smoke control, provide positive indication of air flow with either a flow switch or pressure differential sensor to determine the intended operating status of the fan. Display the status of all smoke control systems on the FSCS. Indicate both visibly and audibly on the FSCS any trouble condition when any smoke control equipment does not respond to automatic or manual commands. The FSCS controls the Sonalert logic for all smoke control systems, no other application is necessary. 6 Metasys System Extended Architecture Smoke Control System Technical Bulletin

7 Prevent the smoke duct detectors from stopping the fan, once the smoke control system has been activated, if the fan is used for smoke control, and the smoke control strategy is such that the return duct will be configured to exhaust the smoke from the building during the smoke control system operation. Duct smoke detectors are often located in the return duct of a Heating, Ventilating, and Air Conditioning (HVAC) fan and connected to stop the fan when smoke is detected, which is in compliance with NFPA 90A. Use the Automatic Weekly Testing of Dedicated Stairwell Pressurization Fans application on all dedicated smoke control systems to verify proper operation. Refer to the Weekly Testing of Dedicated Stairwell Pressurization Fans - Metasys System Extended Architecture Application Note (LIT ) for more information. Use the Automatic Weekly Testing of Dampers application on all dedicated smoke control systems to verify proper operation. Refer to the Weekly Testing of Dedicated Smoke Control Dampers - Metasys System Extended Architecture Application Note (LIT ). Automatic activation of any smoke control sequence of operation must have priority over any automatic environmental control strategy and over any non-smoke control manual commands. When an automatic smoke control sequence is initiated, the system design must bypass the following operational overrides: - High and Low Temperature Protection Devices (specifically, A-11 and A-25 series Temperature Protection Devices) - Return and Exhaust Air Duct Smoke Detectors Make the indication of a trouble condition from any air duct smoke detector available to FSCS operators so that they can make informed decisions concerning their override actions if smoke is detected elsewhere, especially in the supply air. This can be in the form of annunciation on the fire alarm system control panel or a remote annunciator controlled by the fire alarm system. Give the highest priority to the FSCS to manually activate or deactivate any predefined smoke control strategy. Give automatic smoke control a higher priority than any manual or automatic HVAC application. After a smoke alarm is received and acted upon automatically by the smoke control system, additional smoke alarms must not cause the smoke control system to take automatic secondary actions. However, the system must execute any manual commands from the FSCS. Ensure that all communication links between buildings are fiber-optic cable or copper cable buried in a conduit that is separate from power wiring. Metasys System Extended Architecture Smoke Control System Technical Bulletin 7

8 Ensure that response time for individual smoke control components to reach their intended postion from the point of command does not exceed the following time periods: 60 seconds for fan operation at the desired state plus 10 seconds to annunciate; 75 seconds for completion of damper travel plus 10 seconds to annunciate. In the case of fan start after damper close add these times. If the damper must be closed before the fan starts, the total response time could be up to 135 seconds for operation, 75 seconds for damper to close plus 60 seconds for fan to start. Time to annunciate is added to this time. (Control system response is the time from automatic detection of a smoke condition to the issuing of the first smoke control command to the equipment.) Automatic activation of any smoke control sequence of operation has priority over any non-smoke control manual commands and any automatic environmental control strategy, when an auto smoke control sequence is initiated. High and low temperature protection devices and return and exhaust air-duct smoke detectors are bypassed. Use the UL Listed Smoke Control NAE to interface all input and output smoke control points. FSCS Requirements Requirements of an FSCS include the following. The FSCS must have: full monitoring and manual control capability over all smoke control systems and equipment the capability to override (partially or in full) any operation in progress, including programmed actions, non-smoke control manual overrides, and non-smoke control bypasses the highest priority over all smoke control systems and equipment a building diagram clearly indicating the type and location of all smoke control equipment indication of the actual status (not the command status) of systems and equipment used for smoke control. This includes both the full open status and the full closed status of each damper, the status of each fan used for smoke control, and the air flow status of every fan. the ability to activate an audible signal if the operation proof sensor (binary feedback point) failed to provide positive feedback that its command was executed within the allowed response time hardware supervision alarms, such as binary feedback trouble on fans and dampers, as well as the system trouble points, that will turn on the FSCS alarm horn 8 Metasys System Extended Architecture Smoke Control System Technical Bulletin

9 sole control (Use only one FSCS on a Metasys system extended architecure network used for smoke control applications, unless multiple FSCSs are approved by the AHJ.) Note: User must use the approved UL Listed display panel as your FSCS. This panel is available from: Automation Displays, Inc. (ADI) 3533 N. White Avenue Eau Claire, WI (715) The FSCS can be connected to any UL 864 UUKL Listed MS-NAE55-0U in the network. Smoke Control Restrictions The following section describes smoke control restrictions. Smoke Control System Restrictions per UL 864 UUKL Smoke control system restrictions per UL 864 UUKL follow. Do not use: any fire alarm system manual pull stations to initiate automatic smoke control sequences. Only automatic alarm initiating devices such as smoke, heat, or flame detectors should be used. a duct-type smoke detector to initiate a smoke control strategy except as detailed in the Smoke Control Strategies section of this document the Web browser user interface to provide smoke control. The UL listing does not include the Web browser user interface for smoke control and as an FSCS. any Ethernet communication equipment that is not UL listed. All NAE networks are Ethernet-based. Refer to the Metasys System Extended Architecture Smoke Control System Technical Bulletin (LIT ) for more information. DX-9100 Controller Applications The following are smoke control system restrictions per UL 864 UUKL for the DX-9100 controller applications. Any DX-9100 controller used for smoke control must be locked in an enclosure (for example, EN-EWC25-0 or FSCS enclosure) to prevent unauthorized access. Do not use the buttons on the face of the DX-9100 controller to override smoke control points. Metasys System Extended Architecture Smoke Control System Technical Bulletin 9

10 Design Considerations This section outlines the design criteria you should consider when implementing a smoke control strategy. Smoke Movement In general, the movement of smoke will follow the same pattern as the overall air movement within a building. The major influences causing smoke movement include stack effect, air/smoke buoyancy, air/smoke expansion, wind, pressure, and the operating HVAC system. In a fire situation, a combination of these influences usually causes smoke movement. An accepted way of containing smoke within a compartment or an area is to create pressure differences across partitions that separate the affected area from the surrounding areas. You can accomplish this by creating higher pressure in the adjacent space than the pressure which is in the smoke zone. The pressure differential should be sufficient to overcome the effects of wind pressure, the stack effect, the buoyancy of hot gases, and other influences as previously described, yet permit doors leading to emergency exit routes to be opened. In addition, air flow can minimize the movement of smoke through openings such as doors. For example, you can pressurize a stairwell, thereby minimizing the migration of smoke into it. Should one of the stairwell doors open, the flow of fresh air from the stairwell will reduce the movement of smoke into the affected area. Note: Treat elevator shafts like stairwells and positively pressurize them to prevent vertical migration of smoke through the building. You may close inter-floor and inter-area duct work not being used for active smoke control at the appropriate locations, as detailed See Table 1 in the Related Documentation section of this document. Smoke Control Strategies The smoke alarm initiation of an automatic smoke detection device, such as an area-type smoke detector located in one of the facility s smoke zones, generally activates the smoke control system. This activation may initiate a control strategy for the air moving equipment to create higher pressures in the areas surrounding the smoke zone than are present in the smoke zone. This may include positively pressurizing areas adjacent to the smoke zone and/or negatively pressurizing the smoke zone and exhausting air from the smoke zone. Subsequent smoke alarm conditions in other zones must be prevented from automatically changing the initial smoke control sequence. Keep in mind the guidelines provided in this section when planning your smoke control strategy. Note: Do not use duct type smoke detectors exclusively to activate smoke control. This is for the following reasons: 10 Metasys System Extended Architecture Smoke Control System Technical Bulletin

11 The dilution of air in the duct system will likely result in a slow response time. The supply air duct detector, when exposed to outdoor air in the HVAC supply air duct, may report a false alarm condition. The duct system may move smoke from the smoke zone, and this will cause the duct detector in the return/exhaust duct of the non-dedicated fan system to register an alarm condition. Note: It may be acceptable to use a duct smoke detector if it is not exposed to outdoor air, the duct detector s coverage area is equal to the area covered by a spot type area smoke detector (typically 900 square feet or less), and/or the AHJ has approved the application. Initiating Devices The following section describes initiating devices for manual and automatic initiation. Initiating Devices Used for Manual Initiation Do not use manual pull stations to initiate a smoke control sequence, since there is no certainty that manual devices will be activated in the area of involvement. However, you can use manual pull stations to initiate global operations, such as energizing stairwell and elevator shaft pressurization fans. Manual implementation of the smoke control strategy takes place at the FSCS. The FSCS must be capable of overriding, either partially or in full, any automatic activation that may be in progress. It must also be capable of manually controlling each control point (damper, HVAC fan, and so forth) that is used for smoke control in the facility. Refer to the application notes listed in Table 1 for details on how to interface an FSCS to a Metasys system. Interface devices (those that interface field points to the controller) have the following restrictions. They must: be listed for use in the Johnson Controls Smoke Control Listing be used and installed according to Johnson Controls literature result in fan operation at the desired state within 60 seconds (plus 10 seconds to annunciate) when commanded result in completion of damper travel within 75 seconds (plus 10 seconds to annunciate) when commanded For more information, see the LCT Standard Applications Library section of this document. Metasys System Extended Architecture Smoke Control System Technical Bulletin 11

12 Initiating Devices Used for Automatic Initiation You can initiate an automatic operation of a smoke control sequence using a BACnet connected Intelligent Fire Controller (IFC)-640, IFC-1010, IFC-2020 or IFC-3030 panel. End-to-End Verification End-to-end verification is required to ensure that the smoke control sequence of operation has been implemented. Verification must be accomplished by using damper position indicators and air flow switches or differential pressure sensors. Any failure that results in equipment failing to respond (or responding inappropriately) to commands from the Metasys smoke control system must generate an audible and visual trouble signal at the FSCS. For HVAC dampers, used in smoke control sequences, the FSCS must display a positive indication of the damper s fully opened position and its fully closed position and must report a trouble condition if the damper position does not agree with the commanded position. For a permanent record of trouble conditions, including situations where the commanded smoke control sequence does not equal condition, use the audit trail function to record the last commands and events during a Smoke Control Sequence. For additional long term storage of historical data, you must install an Application and Extended Data Server (ADX) outside of the smoke control network. Response Time Response time for individual components to achieve their intended state from the point of command should not exceed the following time periods: 60 seconds for fan operation at the intended state plus 10 seconds to annunciate; 75 seconds for completion of damper travel plus 10 seconds to annunciate. Building HVAC Systems Used in Smoke Control Central Systems Central HVAC systems are frequently employed in smoke control designs. The designer should ensure that the system s capacity is sufficient to supply the quantity of outdoor air necessary to pressurize the areas adjacent to any fire area. The designer should also make sure that the fan systems can handle situations where a fire may expand to other areas, requiring more areas to be positively pressurized. In addition, the installer must install smoke dampers at the duct risers of each floor s supply and return takeoffs as required by NFPA 92A. Pressure controls should also be employed in order to avoid rupturing or collapsing the ductwork. 12 Metasys System Extended Architecture Smoke Control System Technical Bulletin

13 Dedicated Smoke Control Systems Dedicated smoke control systems are fan, damper, and duct systems designed for the sole purpose of controlling smoke within a building. An example of a dedicated system is a stairwell or elevator shaft pressurization system that is operational only during a smoke control event. The dedicated smoke control systems form a system of air movement that is separate and distinct from the building s HVAC system, and they only operate to control the flow of smoke. With their function being dedicated to the performance of smoke control, dedicated smoke control systems are more immune to faults in the building s HVAC system. They are, however, more costly than non-dedicated systems, and because they are not in continuous use, faults may go undetected. Note: To assure full performance and maintain UL compliance, apply automatic weekly testing to all dedicated systems, including dedicated elevator shaft fans, dampers used exclusively for smoke control, and the like. Refer to the Weekly Testing of Dedicated Stairwell Pressurization Fans - Metasys System Extended Architecture Application Note (LIT ) for details on how to perform the necessary tests. Any failure to properly respond in the alloted time must send a trouble signal to the FSCS. Non-Dedicated Smoke Control Systems Non-dedicated smoke control systems share components with other air moving equipment normally used for building environmental control. When the smoke control mode is activated, the operating mode of the building s HVAC equipment changes in order to accomplish the objectives of the smoke control design. Non-dedicated systems tend to be less costly and occupy less of the building s space. However, from an operational standpoint, the control strategy may become elaborate. This may expand the number of control and monitoring points connected to a Building Automation System (BAS) and increases the complexity of the sequence of operation of the air moving equipment. Individual Floor Fan Units If sufficient outdoor air is available and the system has the capability to exhaust an area, individual or floor-by-floor fan units can be used in smoke control applications. Metasys System Extended Architecture Smoke Control System Technical Bulletin 13

14 Fan Coil Units/Water Source Heat Pumps These types of units are generally located on the perimeters of buildings and only draw only enough outdoor air to fulfill the fresh air requirements of the spaces they serve. They are often used in conjunction with central systems, which deliver fresh air and exhaust recirculated air in larger quantities. When the fan coil unit is not located in the smoke zone, it is acceptable to exclude it from the smoke control sequence. When the unit serves the smoke zone in a design that calls for the area to be negatively pressurized, its outdoor air damper should be closed, and the unit should be de-energized. Induction Units During a smoke control mode, induction units that serve the smoke zone should be shut down, or their primary air source should be closed off. Variable Air Volume (VAV) Systems The Variable Air Volume (VAV) system, when employed as part of a smoke control strategy, is a subset of the general central system category described above. Employ control strategies that ensure adequate quantities of air pass through the terminal units to permit floor pressurization in the areas adjacent to the smoke zone. This may include overriding the air volume control to provide maximum deliverable air to the areas adjacent to the fire area. If fan-powered terminal units are used and installed in the smoke zone, shut off their fans. If bypass dampers fulfill the volume control, close the damper during smoke control mode. Smoke Dampers All dampers used as barriers in smoke partitions or as safety dampers in a smoke control system should be UL Listed and Classified for use in that application. (Refer to UL 555S Standard for Leakage Rated Dampers for Use in Smoke Control Systems.) Applying the Metasys Network as a Smoke Control System Air Moving Equipment in a Smoke Control Sequence In general, the equipment you use in an engineered smoke control application is the same as that used in environmental control applications. However, there are some unique components, such as the switch (NU-FIBSW1-0, NU-FIBSW2-0 or NU-RJ45SW1-0), and the FSCS, that must be used to comply with the component performance requirements of the UL 864 UUKL Listing. Also, there may be significant differences in the way the equipment is installed and the quantity and type of control and monitoring points that are connected. 14 Metasys System Extended Architecture Smoke Control System Technical Bulletin

15 Inputs for Smoke Control Figure 1 and Figure 2 detail the various input configurations that are UL Listed for smoke control. This figure shows how an FSCS is connected into a Metasys system using a Smoke Control NAE directly via the N2 Bus. Fire Fighter s Smoke Control Station The FSCS must have full monitoring and manual control capability over all smoke control systems and equipment. It must have the capability to override (partially or in full) any operation in progress, including programmed actions, non-smoke control manual overrides, and non-smoke control bypasses. You may have only one FSCS on a Metasys Network used for smoke control applications unless multiple FSCSs are approved by the AHJ. For more details, see the Smoke Control Requirements section in this document. Intelligent Fire Controllers The IFC-640, IFC-1010, IFC-2020, and IFC-3030 fire alarm control units can be interfaced to the Metasys extended architecture system to initiate smoke control actions by using the BACnet gateway as shown in Figure 1. Output Devices Audible and Visual Notification You must provide visual and audible indication to alert an operator in the event that a programmed smoke control sequence did not occur. This indication must occur at the FSCS. NAE The NAE can be an output device with N2 controllers. Network Integration Engine (NIE) The NIE can be used as an output device by integrating an NCM with N2 controllers. DX-9100 Controllers In more sophisticated control scenarios, use the DX-9100 controller with an XT/XP Input/Output (I/O) Module. The quantity of input and output points required at the DX-9100 controller is generally large. Input wiring connected to these controllers I/O points needs to be shielded or installed in metallic raceway as protection against transients. Refer to the Metasys System Extended Architecture Smoke Control Wiring Technical Bulletin (LIT ) for restrictions on field wiring. All electrical installations must meet the requirements of NFPA 70 National Electrical Code. Refer to the controller s technical bulletin for more information. Metasys System Extended Architecture Smoke Control System Technical Bulletin 15

16 Application Specific Controllers As with other Facility Management scenarios, use UL 864 UUKL Listed Application Specific Controllers (ASCs) as required to meet the needed sequence of operation. Use UL 864 UUKL Listed AHUs, VAVs, VMAs, and Unitary (UNT) controllers in the HVAC scenarios for which they were designed. Your controller selection should account for the fact that operational overrides and safeties are sometimes bypassed and more control outputs may be required. Since positive indication of control action via flow switches and damper end switches (proof sensors) is required, the quantity of input points will generally increase as well. Refer to the Metasys System Extended Architecture Smoke Control Wiring Technical Bulletin (LIT ) for restrictions on field wiring. All electrical installations should meet the requirements of NFPA 70 National Electric Code. Refer to the controller s technical bulletin for more information: Air Handling Unit (AHU) Controller Technical Bulletin (LIT ) Unitary Controller (UNT) Technical Bulletin (LIT ) Variable Air Volume (VAV) Controller Technical Bulletin (LIT ) Variable Air Voulume Modular (VMA) 1200 Series Overview and Engineering Guidelines Technical Bulletin (LIT ). Smoke Control Devices All devices used for smoke control applications must communicate with the UL 864 UUKL Listed NAE (MS-NAE5510-0U). Refer to the NAE55/NIE Installation Instructions (Part No ) for information on installing the NAE. Note: All NAE devices (MS-NAE5510-0U) and the network that connects them must be physically isolated from other non-smoke control NCM, NIE, NAE systems, Web browsers, and all non-listed ethernet network devices, such as hubs, routers, and repeaters, by a switch (NU-FIBSW1-0, NU- FIBSW2-0 or NU-RJ45SW1-0), as detailed in the Smoke Control System Restrictions per UL 864 UUKL section of this document and as shown in Figure 1. Ethernet Switches The switch is the core of a network or cabling system. Ethernet switches for fiber-optic cables (NU-FIBSW1-0 or NU-FIBSW2-0) or copper cables with RJ45 connectors (NU-RJ45SW1-0) have multiple ports to connect multiple cable segments together in a star, bus, or combination of star and bus topology. 16 Metasys System Extended Architecture Smoke Control System Technical Bulletin

17 Network Control Module (NCM) In an NAE-based system, configure the NCM350s only for triggered outputs using integration through an NIE. For systems that have NCM350s as output devices, the UL UUKL Listing requires the Network Interface Card (NIC) (NU-ETH101-0) to be installed in the Metasys system nodes (NU-NCM350-8) to communicate over the N1 LAN/Ethernet network. The NIC installs into the ISA card slot on the NCM350 (NU-NCM350-8). NICs use RJ45 (unshielded twisted pair, copper wire, 8-pin phone jack) ports to connect to a media converter. Only the RJ45 port on the NIC is approved for UL864 (UUKL) smoke control applications. Do not use the Attachment User Interface (AUI) port or coaxial cable port. These ports are not UL UUKL Listed. Media Converters Media converters change signal formats between fiber-optic and NIC (copper cable) output. Media converters require an external 120 VAC power supply. The NU-MC101-0 media converter operates at a 10 Mbps communication speed. See documentation packaged with the media converter (NU-MC101-0) for power requirements. The NU-MC102-0 media converter operates at a 100 Mbps communication speed. See documentation packaged with the media converter (NU-MC102-0 and NU-CH101-0) for power requirements. Repeater The N2 Bus repeater (NU-RPT101-0) isolates the N2 Bus signal. It also regenerates incoming signals, so you can extend transmission distances while maintaining signal quality. In addition to collision detection, the repeater reshapes, re-times, and re-transmits signals to both Ethernet segments. If using an N2 Bus Repeater to isolate the smoke control system, you must place the reapeater inside the smoke control system. Any non-listed devices must be placed outside the smoke control system. Smoke Control Application Examples To help design a smoke control system, Figure 1 shows an example that complies with UL Listings, incorporating smoke control and non-smoke control systems. This is only an example - the number and arrangement of components in your system may differ. Ensure that your system complies with all device and communication requirements and restrictions..

Follow these guidelines when defining systems and objects: Name all systems used for smoke control in a manner that makes identification obvious. For example, the air handling unit serving the west wing on the third floor might be called AHU3_W and the stairwell pressurization system might be called STR_PRES. Name all objects within a system used for smoke control in a manner that makes identification obvious. For example, the outdoor air damper might be called "OSA_DMPR" and the mixed air damper might be called "MXA_DMPR." Use engineering units that are appropriate to easily determine the current status of a device. Use the 24-character expanded ID attribute in an object definition window to provide information that is pertinent to an object s type and location and is easily understood in an emergency situation. Smoke Control NAE Programming Guidelines Create the Metasys system NAE/NIE databases using online system generation and Auto-Discovery. Refer to the SCT Technical Bulletin (LIT ) for more information. 20 Metasys System Extended Architecture Smoke Control System Technical Bulletin

21 NIE Programming Guidelines DDL is required only for smoke control NCMs integrated through the NIE as output devices. Note: Create the Metasys system database using online generation with Data Definition Language (DDL) using an American Standard Code for Information Interchange (ASCII) text editor. See the DDL Programmer s Manual for more information. LCT Standard Applications Library The LCT is a feature of the Metasys system software used to create a graphical representation of the control logic within a system. Examples of automatic smoke control sequences are available in the Standard Applications Library, Smoke Control Applications. Use the smoke control applications as written or modify them to meet your requirements. Manual override operations take precedence over any automatic smoke control sequence of operation. To use the library, refer to the Standard Applications Library provided with the Branch Purchase Package (BPP).
