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.
