Remote Station and Protected Premises Fire Alarm Systems

Introduction

Protected Premises Fire Alarm Systems

A small fire occurred in the elevator lobby of the elderly housing complex.  Its origin was unknown, but this was a good test of the emergency plans in place to address the issue of what happens in an incident.  It is also a good test of the automatic systems put in place to make the facility as safe as possible in the event of a fire...

A review of the incident occurred the next morning.  All of the "variables" were reviewed - the emphasis on how the plan can work better next time.  When the discussion turned to the fire protection systems and automatic features that are in place, the activities of the fire alarm system took center stage. 

The facility had recently installed a new, addressable protected premises system.  The main control unit was relocated to the security/safety office, at the main lobby to the building.  When the incident occurred, the fire alarm system provided the following:
Announcements went out over the multi-channel voice notification system to alert occupants.  The system worked perfectly, as the announcement to the building where the fire originated instructed occupants to relocate.  The rest of the building received different messages, based on the proximity of the fire to their location. The fire doors released in all wings of the building, creating smoke and fire barriers. The elevator returned to the first floor, designated level. All exit doors normally locked to the outside became unlocked for responder access. All HVAC systems were shut down as planned to prevent smoke movement. The new, state-of-the-art exit marking system directed occupants to the exits. Transmission of the fire alarm signal, right down to the specific detector that activated was transmitted, directly to the fire department over the directly connected phone line. All of these things worked like they were supposed to, all because the protected premises fire alarm system did its job.  A success story for sure...
