Early fire detection system EFD III

The EFD system is a compact 19", 1 U early fire detection system with active smoke extraction system.

7338221 / H: 44mm (1.73") W: 490mm (19.29") D: 490mm (19.29")

DescriptionThe EFD III early fire detection system includes the smoke extraction system in a 19" subrack built into just 1 height unit. An integrated fan continuously extracts air from the area to be protected via a pipeline system. The extracted air is passed over two fire detectors. If smoke aerosols are detected the highly-sensitive detector emits a pre-alarm with the second fire detector emitting the main alarm. The correct functioning of the fire detectors is monitored at all times by the evaluation and control electronics on the control board.
