12.5 Day/Night Mode
The control panel has two operating modes: Day and Night. The operating principles of the control
panel depend on the selected operating mode.
12.5.1 Day
Most buildings are occupied during the day, therefore, those in charge of the safety of the building and
its occupants should be duly informed before the “Evacuate” command is given.
Silence:
Silences (switches Off) the panel beeper and silenceable outputs. The Silence command
will be undone automatically, if a new alarm event occurs (another detector signals alarm
conditions).
Pre-alarm: 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 18.1 How to program 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 18.1 How to program loop devices.
12.5.2 Night
Most buildings are empty during the night, and often there is only one person in charge of building
safety (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 18.1 How to program 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 18.1 How to program loop devices.
The Control panel
The Control panel to all effects is a zone that manages 16 signals and the following operating modes:
Investigation, Reset, Silence, Day/Night.
Besides being influenced by manual operations (e.g. INVESTIGATE), the control panel status and
signals can be influenced by the activation of signals generated by input devices, or by the activation
of a group (e.g. Day/Night).
The control panel signals can be used to command the outputs (for example, to monitor a reception
area).
The Groups
A group is a logical unit whose status (TRUE/FALSE) is influenced by other groups, timers and
constant numerical values which make up a logical, mathematical equation. It can also be activated
by a zone (for example, the “Turn Off Air Conditioning” group can be activated directly from a push
button, or by a heat detector Monitor signal or when more than three zones go into Alarm status, or
during holiday periods).
A group can in turn activate/deactivate one or more specific signals of the zone, as well as being used
as an operand of an equation related to another group.
