1.1 Performance Features
– Fulfills the highest aesthetic demands through the flush-mounting design and the
possibility of color toning
– Smooth, easily-cleaned detector surface
– Quick and easy insertion and exchange of the detector thanks to innovative detector
locking mechanism (click and lock principle)
– Easily-visible two-color LED for display of alarm, trouble and test mode
– Self-monitoring of the sensors, with display on the fire panel:
–
Fault indication upon failure of the evaluation electronics or one of the LEDs of the
optical sensor
– Three-stage contamination display (analog value can be read out at service)
– Fault indication in the case of heavy contamination (instead of false alarm)
– Fault indication in the case of CO sensor failure (for the FAP‑OC 520)
– Thanks to integrated isolators, the LSN loop will continue to function in case of wire
interruption or short-circuit of a detector
– Active adjustment of the threshold (drift compensation) if the optical sensor becomes
contaminated
– Active adjustment of the threshold (drift compensation) of the chemical sensor
– Increased detection and false alarm immunity thanks to evaluation of the time behavior of
fire and disturbance variables
– Programmable sensitivity, i.e. can be adjusted to the area of operation
– Flexible network structures, including T‑taping without additional elements
– Automatic or manual address allocation with or without auto‑detection via integrated
rotary switches
– Detector individual identification on the fire panel in the case of alarm
– A pre‑alarm is signaled when 50 % of alarm threshold is reached (indicator in the event
database of the fire panel).
– Serial number, contamination level, operating hours and current analog values can be
read out from each configured detector
– Activation of an external detector alarm display is possible (not for relay bases)
– Activation of external devices by the relay base is possible
– Easily‑accessible connection terminals
– Service accessories for simple and comfortable detector test and exchange
– When using the FAA‑500‑TTL test adapter, an integrated reed switch automatically
switches the detector into the test mode.
– Can be connected to the LSN fire panels FPA‑1200, FPA‑5000, BZ 500 LSN,
UEZ 2000 LSN, UGM 2020 and to other fire panels or their receiver modules with identical
connection conditions.
– EN54-7 and EN54-17 certified
