Use in a Local Security Network (LSN/LSN improved version)

In a Local Security Network, the detectors connected to a fire panel can be operated in the
following operating modes:
Detector Type
FAP-OTC 420
FAP-OT 420
FAP-O 420/
FAP-O 420 KKW
FAH-T 420/
FAH-T 420 KKW
FAP-DO420
FAP-DOT420
FAP-DOTC420
NOTICE!
Planning should take the anticipated total current and line resistance into account to ensure
each detector has an operating voltage of at least 15 V DC.

Use in Areas with Elevated Radioactivity

There are two detector types available especially for use in areas with elevated radioactivity,
such as in nuclear power plants:

Bosch Sicherheitssysteme GmbH
Multi-sensor fire detectors must be planned in line with the guidelines for optical
detectors until a guideline for their planning is developed in collaboration with the VdS
(see also DIN VDE 0833 Part 2 and VDS 2095):
– Maximum monitoring area 120 m
– Maximum installation height 16 m.
If occasional switch-off of the optical sensor is required, the planning must occur
according to the guidelines for heat detectors (see DIN VDE 0833 Part 2 and VDS 2095):
– Maximum monitoring area 40 m
– Maximum installation height 7.5 m.
Maximum permissible air speed: 20 m/s.
FAH-T 420 detectors must be configured according to Class A1R when planning fire
barriers conforming to DIBt.
