1 MODULE 8 Tying the Systems Together: Emergency Control Functions and Interfaces 1

2 OVERVIEW OF MODULE 8 In this module we will: Describe all components, their arrangements and how the systems work Describe the applications of standards and highlight the application of Chapter 21 of NFPA 72 Identify some of the more common non-fire alarm systems Identify methods of inter-connecting systems together Identify applicable codes, OBC, OMC, OFC and standards, NFPA 72, to particular component and show the overall diagram. 2

3 Fire Suppression System Alarm Automatically initiates control of protected premises emergency control functions NFPA Standard: 72: National Fire Alarm and Signaling Code Lisle-Wood Fire District 3

4 Elevators Elevator recall Elevator shutdown First responders use elevators Elevators for occupant-controlled evacuation Standards: ASME A17.1 Safety Code for Elevators and Escalators NFPA 72: Chapter 21 HighRiseOperations/ 4

5 HVAC Duct Detectors Smoke detectors installed in HVAC ducts Designed to shut down the air handler so it will not move smoke throughout a building NFPA Standards: 90A: Standard for the Installation of Air-Conditioning and Ventilating Systems (not a referenced standard) 72: National Fire Alarm and Signaling Code 5

6 Fire & Smoke Dampers A device within an air distribution system to control the movement of smoke and prevent the spread of fire A firefighter s control panel allows manual control Can be automatically initiated NFPA Standards Brand Services 80: Standard for Fire Doors and Other Opening Protectives 92B: Standard for Smoke Management Systems in Malls, Atria, and Large Areas (not a referenced standard) 6

7 Fan Control Example of an emergency control function Fire alarm system can initiate operation or shut down NFPA Standards 72: National Fire Alarm and Signaling Code Grand Spektra 7

8 Door Release Service Intended to prevent smoke transmission from one space to another in one direction only Either closes all doors in the building or all doors in the smoke zone. Magnetic Generally installed so that they release on loss of power Be Safe Direct 8

9 Electrically Locked Doors Any device or system intended to electrically lock a required means of egress door in the direction of egress shall be connected to the fire alarm system Doors are not permitted to be locked to restrict egress unless specifically permitted by governing laws, codes, and standards NFPA Standard: 72: National Fire Alarm and Signaling Code Fixfire/ 9

10 Combination Systems A fire alarm system in which components are used, in whole or in part, in common with a non-fire signaling system. NFPA Standards: 72: National Fire Alarm and Signaling Code 10

11 Mass Notification System Used to provide information and instructions to people in a building(s) or other space using intelligible voice communications and including visible signals, text, graphics, tactile, or other communication methods. NFPA Standard 72: National Fire Alarm and Signaling Code Alertwave, Inc. 11

12 Emergency Alarm Systems A system to provide indication and warning of emergency situations involving hazardous materials and to summon appropriate aid. NFPA Standards 72: National Fire Alarm and Signaling Code Fire Equipment Company Inc. 12

13 Emergency Fire Command Center The principal attended or unattended location where the status of the detection, alarm communications, and control systems are displayed and from which the system(s) can be manually controlled. NFPA Standards 72: National Fire Alarm and Signaling Code Orange County Fire Authority 13

14 Emergency Responder Radio Coverage All new buildings must have approved radio coverage for emergency responders NFPA Standards 72: National Fire Alarm and Signaling Code 14

20 Lessons Learned from Module 8 Elevators can have many emergency control functions, such as elevator recall and elevator shut down. HVAC duct detectors are designed to shut down the air handler so it will not move smoke throughout a building. Door release service closes all doors in the building or all doors in the smoke zone. All buildings must have approved radio coverage for emergency responders. The OBC and the OFC provide regulations for fire command centers and emergency responder radio coverage. 20
