The EFD system is a compact 482.6 mm (19″), 1 U early fire detection system with active smoke extraction system.
- Article number:
- DK 7338.221
- Product description
- The EFD III early fire detection system includes the smoke extraction system in a 482.6 mm (19″) subrack with just 1 U. An integral fan continuously extracts air from the area being protected via a system of pipes. The air drawn in passes two fire detectors. If smoke is detected, the highly sensitive detector will emit a pre-alarm, while the second detector will activate the main alarm. The fire detectors are permanently monitored for correct functioning by the evaluation and control electronics on the control card.
