3.3 Function
3.3.1 Parameter sets
The detection behavior of the detectors is influenced by the parameter sets, so that
it can be specifically adjusted to the fire phenomena and environmental conditions
to be expected in the environment to be monitored.
All parameter sets are programmed in the detectors. To select the parameter set
used, insert the point detector into a certain detector base.
The table below illustrates the dependency between the point detector's parameter
sets and the detector bases used.
Point detector

Detector base
DB110 or DB110D
Detector base
DB110R or DB110RD
OH110 'Sensitive' 'Robust'
OP110 'Standard' 'Sensitive'
HI110 'A1R'
HI112 'A2S' 'B'
3.3.2 Diagnosis levels
The point detector monitors most of its functions itself. In particular it monitors the
correct functioning of the microcontroller, temperature sensors, light emitter and
light receiver.
If there is a fault, the point detector's internal alarm indicator flashes:
