5.1.3 Sensor functions (zone/detector)
Using this function, it is possible to switch off sensors in detector zones or in individual fire
detectors in an analog ring loop.
By entering the zone and detector number, individual sensors can be switched off in each single
multisensor detector.
If only the zone number is entered (detector number = 0), the desired sensor switch-off is
performed for all multisensor detectors in this detector zone. If sensors have already been
switched off in individual multisensor detectors in this zone, the plaintext
message "Switch on/off not
permissible"
appears. All sensors must first be switched on in this zone before the desired sensors
can be switched off.

☞
Switching off sensors is only possible for OH and OHI multisensor fire detectors. If
multisensor fire detectors with unifunctional detectors (detectors with only one sensor) are
installed together in an analog ring loop, only the sensors in multisensor detectors are
switched off.
☞
If a switch-off has already been performed, e.g. the sensors of a zone have been switched
off, this detector zone or the entire analog ring loop cannot be additionally switched off. It is
possible to switch off other detector zones of this analog ring loop in which detectors or
sensors have not been switched off.
