Retrieved fromUnit LessonIn the previous lesson, we learned that the components of fire protection, detection, and suppression arecritical to ensure life safety and the protection of property. In addition, we learned the myth of pulling a manualfire alarm and activating the entire sprinkler system was found to be false. The fire alarm notification system istied to the manual pull station, and pulling the alarm will initiate a signal notifying the monitoring company asto the type and location of the alarm. There are a variety of simple and complex fire alarm systems, and theoptimal performance detection is the first defense against the spread of fire.UNIT III STUDY GUIDEFire Alarm Notification Systems
UNIT x STUDY GUIDETitleAccording to Brakhage, Abrams, and Fortney (2016), fire alarm detection systems range from simple innature to advanced detection systems with microprocessor-based software. Fire detection and fire alarmsystems utilize fire alarm control units (FACU) that receive the signal from the initiating device, whether it is asmoke, heat, light, or gas detection or even water flow. FACUs monitor and control the devices and transmit asignal to a fire alarm monitoring company where the fire department is notified of the location and type ofalarm. In addition, upon activation, the FACU initiates an audible alarm to evacuate the structure. TheNational Fire Protection Association (NFPA) 72 outlines the notification requirements for fire alarmappliances.What notification signaling appliance alerts occupants in a timely manner? Is it bells, buzzers, horns,speakers, strobe, or lights? What is the reliability of notification signaling appliances? Notification signalingappliances provide audible, visual, and textual signals. According to Gagnon (2008), of the different types ofnotification signaling appliances, a three-pulse temporal pattern allows individuals to recognize the alarmsignal in a timely manner. Whether bells, buzzers, or horns, if it is a constant alarm sounding, it becomesambient sound or white noise. The constant alarm is similar to a car alarm where many have become numb tothe sound and, in many cases, not even respond to the sounding alarm even when there is an emergency. Ithappens so often that it has become a nuisance alarm to many believing it to be a false activation. Gagnon(2008) suggested that alarms are ignored because of the failure to recognize the sound, because it is anuisance alarm, or because one cannot hear the alarm. As a result of numerous false alarms in somefacilities, many have been conditioned to the sound.In addition, fire alarm system activation should not impact other zones being evacuated within the samestructure and must be separated by a 2-hour rated wall, and the cabling that carries the notification signalmust be rated for 2 hours (Gagnon, 2008).
