Fire Safety
You can ↑ switch off 'Zones' with automatic or non-automatic detectors in special
situations, e.g., during construction work.
When parts of the fire detection installation are switched off, the fire detection
installation is in 'ISOLATION' condition and operation mode.
The 'ISOLATION' LED on the Person Machine Interface is on.
In 'ISOLATION' operation mode neither 'ALARMS' nor 'Faults' from the parts of the
↑ site that have been switched off can be evaluated.
You can set isolations with or without a time limit.

In the ' --Renovation mode' operation mode, the detector ↑ parameter sets are
changed as follows:
● No evaluation possible by the optical part of the detector.
● A static evaluation by the thermal part of the detector is possible, however,
without the evaluation of the temperature difference.
The 'ISOLATION' LED on the ↑ PMI is on as soon as a part of the ↑ site has
been set to ' --Renovation mode'.
In ↑ normal operation 'ALARMS' are evaluated and processed in accordance with
the 'Manned operation' or 'Unmanned operation' operation mode.
↑ Normal operation is described in the following:
● The detectors are set to normal sensitivity level, in accordance with the
relevant ↑ parameter set.
● The fire detection installation is ready to receive danger messages ('ALARMS')
and fault messages.
● The 'System On' LED lights up.
In normal operation, the fire detection installation may be in the 'Manned operation'
or 'Unmanned operation' operation mode. In the 'Manned operation' operation
mode, the 'Premises manned' LED is on.
'Manned operation'
In the 'Manned operation' operation mode, events can be processed via ↑ 'AVC' or
↑ 'IC'.
The remote transmission of an 'ALARM' may be delayed, for example, and an
operator may verify 'ALARMS' or 'Faults' that have occurred.
'Unmanned operation'
In the 'Unmanned operation' operation mode, events are directly handled in
accordance with the configuration, without taking into account the 'AVC' or 'IC'.
This means e.g. that remote transmission of an 'ALARM' is effected without delay.
Global alarming is activated immediately.
