– Increased detection and false alarm security thanks to evaluation of the temporal
behavior of fire and disturbance variables.
– Activation of a remote indicator is possible.
– Optional mechanical removal safeguard (can be activated/deactivated).
– Dust-resistant labyrinth and cap construction.
– Every detector base has a Chamber Maid Plug (a cleaning opening with a plug) for
blowing out the optical chamber with compressed air (not required for the FAH‑T 420
Heat Detector).
– For connecting to the FPA-5000 and FPA-1200 fire panels with extended range of LSN
features.
– In classic mode, can be connected to the BZ 500 LSN, UEZ 2000 LSN and UGM 2020 LSN
fire panels and to other panels or their receiver modules with identical connection
properties but with the existing LSN system limits.
– It is possible to read out the serial number, contamination level (for the O sensor),
operating hours and current analog values for each configured detector (except for KKW
types) via LSN.
– Use of shielded and unshielded cables.
– The LSN improved version line technology supports the connection of up to 254 FAP‑420/
FAH‑420 series detectors per loop or stub (please observe national regulations in this
regard).
– Flexible network structures without additional elements ("T‑Tapping") are possible.
– Automatic or manual detector addressing selectable.
– Compliant with EN 54, EN 50131 and VdS guidelines.
– The device is supported by the WinPara programming software version 4.85 or higher.
