Alarm verification
When the alarm message is acknowledged on the panel controller, a time to investigate is
started. During this time, the message in the place where the detector generating the alarm is
located must be checked to ensure it is correct. The duration of the verification time can be
freely configured for every detector. See also Fire alarm and Triggering fire verification.
If it is determined during the test that the alarm is genuine, an alarm can either be triggered
manually or by activating a manual call point. The transmission device to the fire department is
activated.
Depending on the configuration, a pre-alarm is displayed for the following alarm delays:

Day and night mode

Notice!
Depending on the configuration, the manner in which the difference between day and night
mode is displayed may differ from that on the system.
Depending on the configuration, an incoming alarm is handled differently in day and night
mode:
Night mode
Night mode has the highest security level. Depending on the configuration, the alarm message
is generally transmitted to the fire department without a delay.
Signaling devices (e.g. sirens) and transmission devices to the fire department or fire
protection systems are activated.
If the transmission device to the fire department is activated, the
Depending on the configuration, a detector in night mode triggers a pre-alarm if intermediate
alarm storage is used as an alarm delay for this detector.

Intermediate alarm storage
If a detector with intermediate alarm storage triggers an alarm, this is displayed as a pre-
alarm on the system. The transmission device to the fire department is not activated. The
detector generating the alarm is reset after the first signal.
The pre-alarm becomes an alarm if the same detector triggers an alarm signal again within
a set time. The time until a main alarm is triggered is shown on the display. The
transmission devices and signaling devices are activated.
Dual-detector dependency
If a detector triggers an initial alarm within a dual-detector dependency, then this is
displayed on the system as a pre-alarm. The transmission device to the fire department is
not activated. The detector generating the alarm is reset after the first signal.
The pre-alarm becomes the main alarm if a second detector in the same logical zone
triggers an alarm. The transmission devices and notification appliances are activated.
Dual-zone dependency
If a detector triggers an initial alarm within a dual-zone dependency, then this is displayed
on the system as a pre-alarm. The transmission device to the fire department is not
activated. The detector generating the alarm is reset after the first signal.
The pre-alarm becomes the main alarm if a second detector in a different logical zone
triggers an alarm. The transmission devices and signaling devices are activated.
