6.4
Two-detector-zone dependency
Alerting facilities, alarm transceivers and fire protection facilities are tripped when two defined
detector zones switch to fire alarm mode. A pre-alarm is triggered when there is an alarm in
the first detctor zone.
6.5
Two-detector dependency
Alerting facilities, alarm transceivers and fire protection facilities are tripped when two detec-
tors in a detector zone switch to fire alarm mode. . A pre-alarm is triggered when there is an
alarm in the first detctor zone.
6.6
Alarm buffering
Threshold detectors:
The detector is reset after it detects an event. The detector signals the event if it recurs within
60 seconds.
Master 20 and the ABM module support alarm buffering.
SIGMASYS and Sinteso detectors do not support alarm buffering.
6.7
Event delay
Event delay for SIGMASYS and Sinteso detectors.
The detector only forwards events that were detected for at least the duration of the time pe-
riod programmed.
6.8
Virtual inputs and outputs
Virtual inputs and outputs can be used for signalling and for the automatic execution of oper-
ating commands.
