General
You can recognize the set operating mode on the LED 'Manned'.

When instructed persons are in the building, the operating mode 'Manned' should
be set.
For this reason the first instructed person entering the building should set the fire
detection control unit to operating mode 'Manned'. The other way round, the in-
structed person who is the last to leave the building should set the fire detection
control unit to operating mode 'Unmanned'.
Procedure
To switch between the operating modes 'Manned' and 'Unmanned', proceed as fol-
lows:
1.
Enable the operating level 2 (password or key).
1.
Press the key 'Manned/Unmanned'.
2.
Check the setting by means of the LED 'Manned'.
Note on control units with an indicator module
The automatic switchover between the operating modes 'Manned' and 'Un-
manned' depends on the set configuration.
When switching from 'Unmanned' to 'Manned', it is possible to have the next
switchover time from 'Manned' to 'Unmanned' indicated (e.g. 18:00; see table
'Configuration').
