The basic concepts of control panel programming
Programming manual
7.7
Day/Night Mode
The control panel has two operating modes: Day and Night. The behaviour of the control panel depends on
the set operating mode
7.7.1
Day
There are people in the building, therefore, those in charge of the safety of the building and its occupants
should be duly informed before the evacuation command is given.
Silence:
silences (turns Off) the panel buzzer and silenceable outputs. The silence command will be
undone automatically, if a new alarm event occurs (e.g. another detector signals alarm
conditions).
Pre-alarm: some points can be programmed to signal pre-alarm status. If no-one intervenes during the
pre-alarm phase, the system will generate an alarm when the programmed pre-alarm time
expires. Refer to paragraph
9.7 - How to configure loop devices
to enable/disable the pre-alarm
time of points.
Alarm:
detectors can be programmed with a Day mode alarm threshold and Night mode alarm
threshold, refer to paragraph
9.7 - How to configure loop devices
.
7.7.2
Night
There are no people in the building, therefore, there is only one person in charge of building safety (e.g.:
night watchman, guard).
Silence:
the silence command will act as a signaling delay. The silence phase will run for the pre-set
time. If no-one intervenes during this phase, the system will undo the silence command and
the alarm will continue.
Pre-alarm: the pre-alarm signal can be disabled on specific points. Alarm events will generate instant
alarms. Refer to paragraph
9.7 - How to configure loop devices
to enable/disable the pre-alarm
time on points during Night mode.
Alarm:
detectors can be programmed with a Day mode alarm threshold and Night mode alarm
threshold, refer to paragraph
9.7 - How to configure loop devices
