5 Second Correlating Revision No. 25-NFPA [ Global Input ] Update the usage of "activate" and "actuate" in accordance with the attached document. Supplemental Information File Name 72_SCR25_Global_Activate.docx Description Approved Submittal Date: Fri Nov 17 16:55:47 EST 2017 Committee This Correlating Revision applies consistent usage of the terms "activate" and "actuate" Statement: throughout the document, in accordance with the following: a) "Activate" is used to describe that something is energized, changed, or moved by electrical power. For example, a control panel activates a notification appliance, or a smoke detector activates an alarm signal. b) "Actuate" is used to describe that something is energized, changed, or moved by physical force. For example, an occupant actuates a manual alarm box, or a solenoid actuates a valve. 2/23

6 * Local Operating Console (LOC). Equipment used by authorized personnel and emergency responders to actuate activate and operate an in-building mass notification system. (SIG-ECS) A Local Operating Console (LOC). An LOC allows users within a building to activateactuate prerecorded messages, deliver live voice messages, observe current status of the main autonomous control unit (ACU), or have similar such ACU operator functions at various locations within the building. An LOC serves a similar function as a remote fire alarm annunciator. However, there can be multiple LOC locations within a building, such as on each floor, at each main entry point, at the switchboard or receptionist's console, or as determined by a risk analysis * Signaling Zone. An area consisting of one or more notification zones where identical signals are activatedactuated simultaneously. (SIG-ECS) * Visual notification appliances, textual visual notification appliances, and loudspeaker notification appliances located in the same area shall be actuated activated and deactivated as a group unless otherwise required by an ECS emergency response plan. (SIG-ECS) A The intent of this requirement is to ensure that persons who are deaf or hard of hearing are alerted to seek additional information regarding an emergency situation. Persons who are deaf or hard of hearing are not always alerted by the loudspeakers that provide evacuation tones or voice instructions. It is intended that the loudspeakers and visual notification appliances located in the same area be actuated activated together whenever tones, recorded voice instructions, or live voice instructions are being provided. (SIG-ECS) Visual alarm notification appliances shall not be activatedactuated when loudspeaker notification appliances are used as permitted by for non-emergency paging. (SIG-ECS) A means for turning off actuated activated alarm notification appliance(s) shall be permitted. 6 [NO CHANGE The deactivation means is manually acted upon by a person, so actuated is the correct term.] * When an occupant notification alarm signal deactivation means is actuated, both audible and visual notification appliances shall be simultaneously deactivated Subsequent Actuation Activation of Initiating Devices Subsequent actuation activation of nonaddressable initiating devices on other initiating device circuits shall cause the notification appliances to reactivate Subsequent actuation activation of addressable alarm initiating devices of a different type in the same room or addressable alarm initiating devices in a different room on signaling line circuits shall cause the notification appliances to reactivate. 8 A It is the intent that both visual and audible appliances are shut off when the notification appliance silence feature is actuated activated on the fire alarm control unit. Per the ADA, it is important not to provide conflicting signals for the hearing or visually impaired. 9 A A valve supervisory, a low-pressure switch, or another device intended to cause a supervisory signal when actuated activated should not be connected in series with the end-of-line supervisory device of initiating device circuits, unless a distinctive signal, different from a trouble signal, is indicated. 10 A Actuation Activation of an initiating device is usually the instant at which a complete digital signal is achieved at the device, such as a contact closure. For smoke detectors or other automatic initiating devices, which can involve signal processing and analysis of the signature of fire phenomena, actuation activation means the instant when the signal analysis requirements are completed by the device or fire alarm control unit software. A separate fire alarm control unit contemplates a network of fire alarm control units forming a single large system as defined in Section 23.8.

7 For some analog initiating devices, actuation activation is the moment that the fire alarm control unit interprets that the signal from an initiating device has exceeded the alarm threshold programmed into the fire alarm control unit. For smoke detectors working on a system with alarm verification, where the verification function is performed in the fire alarm control unit, the moment of actuation activation of smoke detectors is sometimes determined by the fire alarm control unit. It is not the intent of this paragraph to dictate the time frame for the local fire safety devices to complete their function, such as fan wind-down time, door closure time, or elevator travel time Subsequent actuation activation of supervisory initiating devices in other building zones shall cause supervisory notification appliances to actuate activate as required by the system input/output matrix Actuated Activated notification appliances at the protected premises shall continue to operate unless they are manually silenced as permitted by The audible and visible trouble signal shall automatically reactuate reactivate at the control unit every 24 hours or less until trouble signal conditions are restored to normal Subsequent trouble signals shall cause trouble notification appliances to actuate activate as required by the system input/output matrix * Unless otherwise permitted by the authority having jurisdiction, trouble notification appliances at the protected premises of a supervising station fire alarm system arranged in accordance with Chapter 26, that have been silenced at the protected premises shall automatically re-actuatereactivate every 24 hours or less until fault conditions are restored to normal. A In large, campus-style arrangements with proprietary supervising stations monitoring protected premises systems, and in other situations where off-premises monitoring achieves the desired result, the authority having jurisdiction is permitted to allow the re-actuationreactivation to occur only at the supervising station. Approval by the authority having jurisdiction is required so it can consider all fire safety issues and make a determination that there are procedures in place to ensure that the intent is met; in other words, someone is available to take action to correct the problem An open, ground-fault, or short-circuit fault on the installation conductors of one alarm notification appliance circuit shall not affect the operation of any other alarm notification appliance circuit for more than 200 seconds regardless of whether the short-circuit fault is present during the normal or actuated activated circuit state When the fire alarm system has been actuatedactivated, and mass notification has been given priority over the fire alarm system, a distinctive audible and visual indication shall be provided at the building fire alarm control unit to indicate MNS is active Manually actuated activated loudspeakers shall be permitted in exit stair enclosures, exit passageways, and elevators in buildings that have emergency voice/alarm communications systems in accordance with Section If multiple notification appliance circuits are provided within a single zone, all of the notification appliances within the zone shall be arranged to actuate activate or deactivate simultaneously, either automatically or by actuation of a common manual control Where there are different notification appliance circuits within a signaling zone that perform separate functions, such as presignal and general alarm signals and predischarge and discharge signals, they shall not be required to actuate activate or deactivate simultaneously * Where required by the emergency response plan, the mass notification system shall provide the capability for authorized personnel to remotely actuate activate live and prerecorded emergency messages *

8 During the period after the mass notification system has seized control of the audible and visual notification appliances, but before the mass notification system relinquishes control, the mass notification system shall actuate activate the audible and visual notification appliances at least once every 30 seconds The in-building mass notification system shall not be actuated activated or controlled by a wide-area mass notification system, unless the wide-area mass notification system also meets the design and performance requirements of this chapter or has been deemed to be acceptable by the risk analysis and the authority having jurisdiction When a remote communications station(s) is actuated activated by a building occupant(s), a two-way live voice communication shall be required to operate between the remote communications station(s) and a constantly attended location The system operator shall be able to broadcast live voice signals or actuated activated prerecorded voice messages, tones, and other signals. 25 A Response. Responses can be effected manually or automatically. One response to a signal might be to actuate activate notification appliances or transmitters, which in turn generate additional signals. See A A Alarm Response. Examples include actuation activation of alarm notification appliances, elevator recall, smoke control measures, emergency responder dispatch, and deployment of resources in accordance with a risk analysis and the associated emergency response plan. 27 A Pre-Alarm Response. Examples include the actuation activation of appropriate notification appliances, dispatch of personnel, investigation of circumstances and problem resolution in accordance with a risk analysis and action plan, preparation for a potential alarm response, and so forth. 28 A Supervisory Response. Examples include the actuation activation of supervisory notification appliances, the shutdown of machines, fan shutdown or activation, dispatch of personnel, investigation of circumstances and problem resolution in accordance with a risk analysis and action plan, and so forth. 29 A Alarm Signal. Examples of alarm signals include outputs of actuated activated alarm initiating devices, the light and sound from actuated activated alarm notification appliances, alarm data transmission to a supervising station, and so forth. 30 A Fire Alarm Signal. Examples include outputs from actuated activated fire alarm initiating devices (manual fire alarm box, automatic fire detector, waterflow switch, etc.), the light and sound from actuated activated fire alarm notification appliances, fire alarm data transmission to a supervising station, and so forth. 31 A Pre-Alarm Signal. Examples include outputs of analog initiating devices prior to reaching alarm levels, the light and sound from actuated activated pre-alarm notification appliances, aspiration system outputs indicating smoke at levels below the listed alarm threshold, and so forth. 32 A Supervisory Signal. Examples include actuated activated supervisory signal-initiating device outputs, supervisory data transmissions to supervising stations, the light and sound from actuated activated supervisory notification appliances, a delinquency signal indicating a guard's tour supervisory condition, and so forth. The term guard's tour supervisory signal, associated with systems supporting guard's tour supervisory service, is a message indicating that a guard has actuated a guard's tour reporting station (not in itself an indication of a supervisory condition). Guard's tour supervisory signals are not a subset of the general category of supervisory signals as used in this Code. 33 A Trouble Signal. Examples include off-normal outputs from integrity monitoring circuits, the light and sound from actuated activated trouble notification appliances, trouble data transmission to a supervising station, and so forth.

9 34 A Nuisance Alarm. Nuisance alarms are unwanted alarms. Sometimes nuisance alarms might be called false alarms. In this Code, any unwanted alarm is considered false because they are not indicative of real hazards. Because the term false has been used by many people to mean many different things, this Code is instead using the terms unwanted, nuisance, and malicious to categorize the different types of alarms. They occur when some condition simulates a fire or other hazardous condition. For example, cigarette smoke can actuate activate smoke detectors and smoke alarms. In that case, there might not be anything wrong with the smoke detector or smoke alarm it is doing its job responding to the condition or stimulus that it was designed to detect. Another example would be a heat detector or heat alarm that actuates activates when someone inadvertently points a hair dryer towards it. A malicious alarm occurs when someone intentionally actuates the detector or alarm when there is no fire hazard. See the definitions of malicious, unintentional, unknown, and unwanted alarms. 35 A Signaling Zone. A notification zone is the smallest discrete area used for any announcements or signaling. Depending on the emergency response plan, a signaling zone can encompass several notification zones. For example, in most highrise buildings, each single floor (fire area) is a notification zone. Most emergency response plans call for the signaling zone to be the fire floor, floor above, and a floor below. For example, the floors of a high rise that are playing the evacuation message and the wait in place message would be in the same notification zone, because they are actuated activated simultaneously. The word identical clarifies that the notification zone is communicating a common message. 36 A Effective intensity is the conventional method of equating the brightness of a flashing light to that of a steadyburning light as seen by a human observer. The units of effective intensity are expressed in candelas (or candlepower, which is equivalent to candelas). For example, a flashing light that has an effective intensity of 15 cd has the same apparent brightness to an observer as a 15 cd steady-burning light source. Measurement of effective intensity is usually done in a laboratory using specialized photometric equipment. Accurate field measurement of effective intensity is not practical. Other units of measure for the intensity of flashing lights, such as peak candela or flash energy, do not correlate directly to effective intensity and are not used in this code. Visual notification appliances might be used to signal fire or other emergencies and might be intended to initiate evacuation, relocation, or some other behavior. Lights intended to initiate evacuation due to fire are required by the Code to be clear or white. Colored lights, such as amber/yellow lights, might be used in a combination system for any emergency (fire, bomb, chemical, weather, etc.) when the intent is for the signal recipient to seek additional information from other sources (voice, text displays, and so on). Example Scenario 1: A building has a fire alarm system used for general evacuation. A separate mass notification system is used to provide voice instructions and information in the event of non-fire emergencies. The fire alarm system would have white/clear visual notification appliances intended to alert occupants of the need to evacuate. The mass notification system would have amber/yellow visual notification appliances that are intended to signal the need to get additional information from either audible voice announcements, text or graphical displays, or other information sources controlled or operated from the mass notification system. In the event that both systems are actuated activated at the same time, the visual notification appliances should be synchronized per Example Scenario 2: A building has a mass notification system that provides information and instructions for a variety of emergency situations, including fire. Fire alarm initiation might be by a stand-alone fire detection system or might be an integral part of the mass notification system. In the event of an emergency, textual audible appliances are used to provide information. Visual signaling could be accomplished using one set of clear or colored visual notification appliances to indicate the need to get additional information. Visual textual information can be provided by text or graphic display or other visual information appliances. The content of the audible and visual messages will vary depending on the emergency.

10 Second Correlating Revision No. 7-NFPA [ Global Input ] Update the usage of "visual" and "visible" in accordance with the attached document. Supplemental Information File Name 72_SCR7_Global_Visual.docx Description Approved Submittal Date: Wed Nov 15 09:39:20 EST 2017 Committee Statement: This Correlating Revision applies consistent usage of the terms "visual" and "visible" throughout the document, in accordance with the following: a) "Visual" is used to describe that something is perceived by sight. For example, a strobe provides visual notification by producing high-intensity bursts of light. b) "Visible" is used to describe the condition of whether an object can be seen by an occupant. For example, a strobe is not visible if it is behind a curtain. 3/23

11 1 18.9* Textual and Graphical Visible Visual Appliances Textual and graphical visible visual appliances shall be permitted to be used to signal information about fire or other emergency conditions or to direct intended responses to those conditions Textual visualvisible appliance messages shall be permitted to be static, flashing, or scrolling Mounting. Desktop and surface-mounted textual and graphical visual notification appliances shall be permitted Performance. The information produced by textual and graphical visualvisible appliances shall be clear and legible at the intended viewing distance. 5 A Effective intensity is the conventional method of equating the brightness of a flashing light to that of a steadyburning light as seen by a human observer. The units of effective intensity are expressed in candelas (or candlepower, which is equivalent to candelas). For example, a flashing light that has an effective intensity of 15 cd has the same apparent brightness to an observer as a 15 cd steady-burning light source. Measurement of effective intensity is usually done in a laboratory using specialized photometric equipment. Accurate field measurement of effective intensity is not practical.

Lights intended to initiate evacuation due to fire are required by the Code to be clear or white. Colored lights, such as amber/yellow lights, might be used in a combination system for any emergency (fire, bomb, chemical, weather, etc.) when the intent is for the signal recipient to seek additional information from other sources (voice, text displays, and so on). Example Scenario 1: A building has a fire alarm system used for general evacuation. A separate mass notification system is used to provide voice instructions and information in the event of non-fire emergencies. The fire alarm system would have white/clear visual notification appliances intended to alert occupants of the need to evacuate. The mass notification system would have amber/yellow visual notification appliances that are intended to signal the need to get additional information from either audible voice announcements, text or graphical displays, or other information sources controlled or operated from the mass notification system. In the event that both systems are activated at the same time, the visual notification appliances should be synchronized per Example Scenario 2: A building has a mass notification system that provides information and instructions for a variety of emergency situations, including fire. Fire alarm initiation might be by a stand-alone fire detection system or might be an integral part of the mass notification system. In the event of an emergency, textual audible appliances are used to provide information. Visual signaling could be accomplished using one set of clear or colored visual notification appliances to indicate the need to get additional information. Visible Visual textual information can be provided by text or graphic display or other visual information appliances. The content of the audible and visible visual messages will vary depending on the emergency. 6 A.18.9 Textual and graphical visualvisible appliances are selected and installed to provide temporary text, permanent text, or symbols. Textual and graphical visualvisible appliances are most commonly used in the private mode for fire alarm systems. The use of microprocessors with computer monitors and printers has resulted in the ability to provide detailed information in the form of text and graphics to persons charged with directing emergency response and evacuation. Textual and graphical visualvisible appliances are also used in the public mode to communicate emergency response and evacuation information directly to the occupants or inhabitants of the area protected by the system. For both private mode and public mode signaling, text and graphic annunciators can provide information about pre-alarm, alarm, trouble, and supervisory conditions. Because textual and graphical visualvisible appliances do not necessarily have the ability to alert, they should only be used to supplement audible or visual notification appliances. Textual and graphical visualvisible information should be of a size and visual quality that is easily read. Many factors influence the readability of textual visualvisible appliances, including the following: (1) Size and color of the text or graphic (2) Distance from the point of observation (3) Observation time (4) Contrast

12 (5) Background luminance (6) Lighting (7) Stray lighting (glare) (8) Shadows (9) Physiological factors While many of these factors can be influenced by the equipment manufacturer and by the building designers, there is no readily available method to measure legibility. 7 A The minimum height for textual and graphic visualvisible appliances is given as 40 in. (1.02 m) above the ground or finished floor. However, the character or symbol sizes should be based on the height of the highest character or symbol displayed by the appliance In-Building Mass Notification System. A system used to provide information and instructions to people in a building(s) or other space using intelligible voice communications and including visible visual signals, text, graphics, tactile, or other communication methods. (SIG-ECS) Paging System. A system intended to page one or more persons by such means as voice over loudspeaker, coded audible signals or visible visual signals, or lamp annunciators. (SIG-PRO) Textual Visible Visual Notification Appliance. See , Notification Appliance The secondary power supply for textual visible visual notification appliances shall be in accordance with * Visible Visual notification appliances, textual visible visual notification appliances, and loudspeaker notification appliances located in the same area shall be activated and deactivated as a group unless otherwise required by an ECS emergency response plan. (SIG-ECS) A The intent of this requirement is to ensure that persons who are deaf or hard of hearing are alerted to seek additional information regarding an emergency situation. Persons who are deaf or hard of hearing are not always alerted by the loudspeakers that provide evacuation tones or voice instructions. It is intended that the loudspeakers and visible visual notification appliances located in the same area be activated together whenever tones, recorded voice instructions, or live voice instructions are being provided. (SIG-ECS) 13 A Mass Notification System. A mass notification system can use intelligible voice communications, visible visual signals, text, graphics, tactile, or other communications methods. The system can be used to initiate evacuation or relocation or to provide information to occupants. The system can be intended for fire emergencies, weather emergencies, terrorist events, biological, chemical or nuclear emergencies, or any combination of these. The system can be automatic, manual, or both. Access to and control of the system can be from a single, on-site location or can include multiple command locations, including some remote from the area served. Systems can be wired, wireless, or some combination of the two. 14 A Control unit signals can be audible, visiblevisual, or both for any particular function. Some older systems used only audible indicators that had to be coded for users to know what the signal meant. Where a control unit uses both audible and visible visual indicators, the purpose of the audible signal is to get someone's attention. In large system configurations, there might be multiple control units with audible signals. Also, there might be several different functions requiring an audible alert as a part of the whole signal. Thus, there could be several different audible signals. It is not the intent of this Code to have separate and distinct audible signals where clear visual distinction provides the user with the needed information. Visible Visual signals, whether a lamp with a text label, an LCD screen, a computer monitor, or other textual visible visual appliances, are better forms of human interface. 15 F.2.11 System with Supervised Audible Notification Appliance Circuit and Unsupervised Visible Visual Notification Appliance Circuit. Testing of the notification appliances connected to Class B is similar to that described in F.2.4. See Figure F Figure F.2.11 Supervised Audible Notification Appliance Circuit and Unsupervised Visible Visual Notification Appliance Circuit.

All input signals should be verified according to the system matrix of operation to ensure they create the appropriate outputs. Tests of audible notification appliances and emergency control functions should be conducted at the conclusion of satisfactory tests of all inputs. The intent is to reduce the amount of time spent causing audible and visible visual occupant notification during tests in an occupied building. This reduction will help reduce the negative (cry wolf) impact on occupants caused by excessive operation of notification appliances. System printouts or history logs are an effective way of verifying the correct receipt of signals. However, many outputs such as occupant notification and emergency control functions are tested for correct operation, because logs do not necessarily verify operation of the system output. Operation of audible and visible visual notification appliances could be accomplished in a lump sum fashion after all inputs are proven correct by silent testing. All inputs tested in this manner must be proved to cause the appropriate signal by verifying alarm receipt at the controls as each device is actuated. Manufacturer-specific protocols such as walk test or alarm bypass are an acceptable means of testing under this section. Other methods of mitigating the negative impact include off-hours tests when the building is not occupied.

22 ] Second Correlating Revision No. 19-NFPA [ New Section after Household carbon monoxide detection systems shall be tested in accordance with the manufacturer s published instructions * Notwithstanding other requirements of , the occupant of a dwelling unit shall be deemed qualified to perform inspection, testing, and maintenance on an alarm system protecting that dwelling unit when provided with information and training from the manufacturer or a manufacturer s certified representative. A Permanent occupants (whether renters or owners) of a dwelling unit should be provided with training and information sufficient to operate, inspect, test, and maintain their own alarm systems. The training should cover basic maintenance requirements, testing and troubleshooting procedures, and contact information for further support. It is not intended that occupants be trained to a level similar to a factory technician or to qualify them to redesign, program, or extend their systems. Submittal Date: Wed Nov 15 14:00:23 EST 2017 Committee Because testing requirements for HOUSEHOLD systems is spelled out specifically in this Statement: section, and the entirety of Ch.14 does not always apply, it is important to note the requirements for testing in accordance with the manufacturer's published instructions. This section is also intended to clarify that occupants of a dwelling unit should be permitted to operate and maintain their own systems without specialized support. This is appropriate because occupants have a direct, vested interest in their own personal safety. Existing language could be construed to require that occupants must retain professional support for routine testing and maintenance. However, it is not the intent of this section to permit nonoccupant owners or facility managers to perform such inspection, testing and maintenance on dwelling units that they manage but do not occupy.
