Fire Alarm System Components

Modern detection and signaling systems vary in complexity from those that are simple to those that incorporate advanced detection and signaling equipment. Such systems are typically designed and installed by qualified individuals as determined by the AHJ. The design, installation, and approval of a fire detection and alarm system may also require acceptance testing by regulatory agencies before new buildings are occupied or the system is placed in service. The design and installation of the fire detection and alarm system should conform to applicable provisions of NFPA® 70, National Electrical Code®, and NFPA® 72, National Fire Alarm and Signaling Code, and locally adopted codes and ordinances. Other standards also apply to the installation of these systems and are addressed later in this chapter within the discussions of the various types of systems. Each of the following sections highlights a basic component of a fire detection and alarm system.

Fire Alarm Control Units:

he fire alarm control unit (FACU), formerly called the fire alarm control panel (FACP), contains the electronics that supervise and monitorthe integrity of the wiring and components of the fire alarm system. The FACU basically serves as the brain for the alarm system (Figure 14.2). It receives signals from alarm-initiating devices, processes the signals, and produces output signals that activate audible and visual appliances. The FACU also transmits signals to an off-site monitoring station when provided. Power and fire alarm circuits are connected directly into this panel. In addition, the remote auxiliary fire control units and notification appliance panels are considered to be part of the fire alarm system and are connected and controlled. Controls for the system are located in the FACU (Figure 14.3, p. 610). The FACU can also perform other functions, such as: • Providing two-way firefighter communication • Providing remote annunciator integration • Controlling elevators, HVAC, fire doors, dampers, locks, or other fire protection features The FACU can also provide public address messages and mass notifications alerts through prerecorded evacuation messages or independent voice communications

Additional Alarm System Functions:

Building codes have special requirements for some types of occupancies in case of fire. In these cases, the fire detection and alarm system can be designed to initiate the following actions: • Turn off the heating, ventilating, and air-conditioning (HVAC) system • Close smoke dampers and/or fire doors (Figure 14.8) • Pressurize stairwells and/or operate smoke control systems for evacuation purposes • Unlock doors along the path of egress • Provide elevator recall to the designated floor and prevent normal operations (Figure 14.9). • Operate heat and smoke vents • Activate special fire suppression systems, such as preaction and deluge sprinkler systems or a variety of special-agent fire extinguishing systems

Alarm Signaling Systems:

Fire detection and alarm systems are designed to receive certain types of signals from devices and perform an action based upon the type of signal received. Some signals may indicate a fire condition, while others may indicate that a device on the system needs to be serviced. The FACU should be programmed to respond to different signal types in an appropriate manner. Fire detection and alarm systems are equipped with three types of specialty signals, depending on the type and nature of the alarm they are reporting: • An alarm signal is a warning of a fire emergency or dangerous condition that demands immediate attention. Locally adopted codes may require fire alarm signals from systems monitored by a supervising station to notify the responding fire department. Activation of smoke detectors, manual pull stations, waterflow switches, and other fire extinguishing systems are all initiating devices that send fire alarm signals. • A supervisory signal indicates an off-normal condition of the complete fire protection system. Supervisory signals also include a returned-to-normal signal, meaning that the condition has been resolved. These signals are used to monitor the integrity of the fire protection features of the system. • A trouble signal indicates a problem with a monitored circuit or component of the fire alarm system or the system’s power supply. Each signal must be audibly and visually displayed at the FACU in a distinct manner that differentiates one type of signal from another. Trouble conditions include loss of primary power or failure or removal of an initiating device, such as a smoke detector.
