1 1 Exam Prep Fire Alarm Signaling Systems Tabs and Highlights These 1 Exam Prep Highlights are based on the Fire Alarm Signaling Systems, 4th Edition. Each Tabs sheet has five rows of tabs. Start with the first tab at the first row at the top of the page; proceed down that row placing the tabs at the locations listed below. Place each tab in your book setting it down one notch until you get to the bottom of a page. Then start back at the top again. After each Tab, under "Reason" is a brief explanation of the purpose of the tab, and/or items to highlight in the section. 1 Exam Prep Tab Pg. # Reason/Highlight Table of Contents V Brief Contents History 1 The History of Fire Alarm Systems Fire Signatures 13 Establishing Fire Protection Goals and Understanding Fire Signatures 15 Fire Signature Fundamentals 20 IR and UV Radiant Energy: earliest signatures detected. Gas Signatures 19 Gas Signatures 24 Transport of Fire Signatures Fire detectors typically sense one of three parameters: (1) (3). Communication Sys. 29 Basic Communication Principles and Design Principles & Design 34 Equipment 35 Speakers shall not be located near the emergency voice/alarm communications system control equipment or a local operating console of a mass communications system (MNS). Systems Types 41 Types of Systems 42 Table 4.1 Types of Fire Alarm Signaling Systems Auxiliary Systems 46 Auxiliary Alarm Systems There are two types of auxiliary systems recognized in NFPA 72: (1) (2). Figure 4.4 Local energy type auxiliary alarm system. 48 Figure 4.6 Shunt-type auxiliary system. 49 NFPA 72 specifies that shunt-type systems are to be used for manual fire alarm and waterflow alarm service only. 1 Exam Prep Fire Alarm Signaling Systems, 4th Edition 1

Maximum permitted shut loop is 750 ft. in conduit. 50 Supervising Station Alarm Systems Figure 4.8 Supervising station alarm systems 52 Proprietary Supervising Station Alarm Systems 53 Proprietary systems are widely used in large commercial and industrial occupancies. Voice Systems 60 In-Building Fire Emergency Voice/Alarm Communications System As defined by NFPA 72, the purpose of an in-building fire emergency voice/alarm instructions pertaining to a fire emergency to the building occupants and the fire department. It standby power supply must operate the entire voice/alarm signaling service for a fire or other emergency condition for 24 hours for 15 minutes. Components & 67 Fire Alarm System Components and Circuits Currents 69 Primary (Main) Power Supply The primary (main) power supply may be provided by a commercial light and supply or an engine-driven generator. Secondary Power Supply for Protected-Premises Systems The secondary power supply must provide power to the complete system within 10 seconds typically below 80 percent of the nameplate voltage) for proper operation. 70 Secondary Power Supply for Supervising Station Facilities The secondary power supply must automatically provide power within 60 seconds minimum voltage required for proper operation. 71 Monitoring of Power Supplies, System Circuits, and Equipment. All fire alarm and process-monitoring alarm supervisory systems should be electrically monitored Power supplies, system circuits, and certain equipment in a fire alarm system are monitored. 73 Circuit/Pathway Performance 74 Class A: A pathway is designated Class A when it performs as follows: 1-3. Class B: A pathway is designated Class B when it performs as follows: 1-3. Class C: A pathway is designated Class C when it performs as follows: Exam Prep Fire Alarm Signaling Systems, 4th Edition 2
