7338221 - RITTAL - Early fire detection system EFD III

The EFD system is a compact 482.6 mm (19"), 1 U early fire detection system with active smoke extraction system.

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.

Features:
• Early fire detection
• 482.6 mm (19") rack mount with just 1 U
• Tested by VdS Schadenverhütung GmbH
• CAN bus interface to the CMC III monitoring system
• Floating relay outputs (pre-alarm/main alarm/collective fault)
