Addressable Fire Alarm System


Why an Addressable Fire Alarm System?

An addressable fire alarm system is one in which all fire and smoke detection devices in a system are connected and communicate both with each other and a central control monitoring location. This interconnectivity allows the control personnel to identify the location or “address” where the initial detection occurred. The information directs the emergency response team to pinpoint their efforts immediately to the precise location of the developing problem.

Linking all devices offers several advantages that are not possible with traditional independent fire alarms. Some of the benefits of an addressable system are:

  • Accurate identification of where the problem started and where it may be spreading
  • Specific actions can be programmed such as delaying evacuations from areas not immediately threatened, thereby reducing bottlenecks of evacuating occupants
  • Reduces potential for false alarms
  • Each element of the system can be monitored routinely for operational health

How Does an Addressable Fire Alarm System Work?

Each detection and notification device is connected to each other. Moreover, each device is connected directly to the central addressable fire alarm control panel which is continually sending messages to check on the functionality of each instrument. In response, each element sends back a report that informs the control panel of its current health. If for any reason a device does not respond, the control panel indicates a problem at that particular address. Authorized technicians from the fire alarm maintenance company can immediately proceed to the location, fix or replace the problem device, and the issue is solved.

Quick Recognition Outbreak Location

Direct identification of the site of the outbreak is beneficial for several reasons. Occupants can initiate immediate evacuation from the adjacent areas while others receive notification to evacuate in the opposite direction from that location to prevent crowding.
