Fire Suppression Detection Systems

A fire suppression detection system is a set of electric/electronic devices/equipment working together to detect fire and initiate the release of the suppressant/extinguishant. The system can either be a standalone system that is linked to the main fire alarm or through cause and effect programming part of the main addressable fire alarm system.

Suppression Detection Systems are normally arranged as a “double knock system” this is to minimise the unnecessary release of the suppressant/extinguishant through false alarm.

The system unlike a Fire Alarm usually has two different types of audible/visual devices to indicate 1st and 2nd stage alarm conditions.

The 1st stage alarm is to alert occupants or the “responsible person” that there has been an activation of one device it the protected area. At this point no suppressant/extinguishant will be released.

The 2nd stage alarm is to alert occupants or the “responsible person” that there has been a 2nd activation from another device/zone and that the suppressant/extinguishant is about to be released this is normally after a time delay to enable the occupants to evacuate the protected area.
