IntroductionsUnder the rather broad heading of fire protectionsystems, this module will examine the maincomponents of alerting, suppression, andcontainment features and systems. Considerationof these systems is a natural adjunct to adiscussion of hazards and building constructionfeatures.The primary components we will examine are firealarm systems, fire detection and notificationsystems, suppression agents and systems,standpipe and hose systems, and portable fireextinguishers. This module will cover a lot of basicmaterial meant to provide the basic audit to ourexisting Fire Protections system.
Fire Alarm SystemsPurpose of Fire Alarm SystemsA properly designed, installed, operated, and maintained fire alarmsystem can reduce the losses associated with an unwanted fire in anybuilding. These losses include property and, more importantly, humanlife. The primary motivation for fire alarm system requirements inbuilding and fire codes is to provide early notification to buildingoccupants so they can exit the building, and to notify the fire service soit can respond to the fire. In settings such as hospitals the fire alarmsystem provides notification to staff so they can respond to the fireemergency (as opposed to evacuating the building). This module willexplain the basic features of fire alarm systems and the inspection ofthese systems. It should be noted that fire alarm systems also arecalled "protective signaling systems," especially in NFPA documentsand in other codes and standards.
