About This Product

■Summary

The EFD is a small (19 inch, 1 U) fire early detection device with an active smoke extraction system.

■Product description

Fire Early Detection Device EFD III's smoke detection system is housed in a 19-inch chassis that is only 1U in size. The built-in fan intermittently draws air from the protected area through a sampling pipe system. The inhaled air passes through two fire detectors. First, a highly sensitive sensor will issue a pre-alarm when it detects a smoke particle, and when a second sensor detects it, it will issue a main alarm. Fire detectors are constantly monitored for proper functioning by analysis and control electronics on the control board.

■Advantages

・Early fire detection ・19 inch slide-in unit, only 1 U ・Inspection by VdS Schadenverhütung GmbH ・CAN bus interface for CMC III monitoring system ・Potential-free relay output (pre-alarm, main alarm/batch abnormality notification)

■Interface

・4 x/3 x alarm and fault relay outputs (terminal/RJ12 socket) ・1 x/1 x input for door contact switch (terminal/RJ12 socket) ・2 x Master-Slave CAN connection for network ・3 x connectors (external emergency notification / manual alarm / tank and fill level) ・1 x Power output for DET-AC III Slave (24 V DC, max. 500 mA) ・1 x USB ・2 x CAN bus interface to CMC III (up to 16 connections to PU / up to 4 connections to PU compact)

■Sensor technology

・Optical smoke detector (sensitivity: approx. 3.5%/m transmitted light turbidity) ・Optical smoke detector HS (sensitivity: approx. 0.25%/m transmitted light turbidity)
