Fire Alarm Systems (FAS)

Fire alarm systems encompass a coordinated array of devices designed to identify the presence of smoke, fire, carbon monoxide, or other emergent situations, subsequently alerting individuals within proximity through visual and auditory indicators. These systems can be triggered automatically by devices like smoke or heat detectors or manually through mechanisms such as manual call points or pull stations. The complexity of the alarms can vary, from elementary motorized bells or affixed sounders to sophisticated speaker strobes that emit an initial alert succeeded by a prerecorded directive advising occupants against elevator usage.
