5.3 Event processing
5.3.1 Alarm
The processing of alarm events is programmable mainly to prevent the unneces-
sary turnout of fire department for minor incidents. It involves personnel in the
alarming sequence and relies on the operating mode manned. The system has to
be run in operating mode manned as long as the responsible personnel is present.
Mode manned has to be de-activated if the responsible personnel leaves the build-
ing.
Programmable parameters
Zone type
via timer V1/V2 in mode manned ; for detectors
direct ; for manual call point, sprinkler alarms, etc.

Timer for detector zones in mode manned
range of V1 0.5 ... 4min; time to acknowledge the system before RT-Alarm is ini-
