The operating states “manned” and “unmanned” are defined in a SPECIAL Alarm Concept,
where signals from automatic fire detectors and manual call points are processed differently (for
details page 16).
The switchover from the operating states “manned” to “unmanned” and vice versa is either done
manually by the operating personnel or automatically as programmed by the service engineer.

The automatic switchover is used for example, to prevent the system status “manned” during
nighttime when no operating personnel is present: The system switches automatically to status
“unmanned” at a defined time (e. g. after the office hours). The same scheme can be used for
unattended times during weekends or holidays. The automatic switchover scheme is defined by
the service engineer. No user action is required.
Automatic switchover from “manned” to “unmanned”: at p.m.
Automatic switchover from “unmanned” to “manned”: at a.m.
The function “extra time” allows to set the system to manned operation for a preset time, after the
automatic switchover to unmanned has taken place.
