OPERATION
Choice of the system configuration
AF921 allows to have two different system protection solutions:
3. traditional alarm system. By programming the zones (A-B-C) in this way, the general alarm will be
activated upon detection of the intruder.
4. pre-alarm system. It is obtained by programming a zone (A-B-C) as an external zone. The detectors
connected and located outside the house, emit a pre-alarm upon detection (optical/acoustic signal,
sounders excluded). If the intruder keeps going in and is detected by a detector connected to a
programmed zone as per the above item, the general alarm will be activated.
Warning: the detectors operating outside the house may generate false alarms due to unavoidable natural
phenomena that interact with the devices. The suitable choice of the devices, their proper installation and
programming of 2 detectors operating in AND mode on the same alarm channel allow to reduce false alarms
significantly. However, it is recommended not to connect outdoor detectors on the zones programmed as per item
1.
Note: The default operating mode is set as traditional , to set it as pre-alarm select Y and item EXTERNAL
ALARM in the related zone menu ( ALARM ZONE A, B and C ) located in programming menu DEVICES.

is silenced by switch-off
