ANOMALY OUTPUT
The sounder is managed by a microcontroller able to check battery recharge, battery status and the speaker; in
case of anomaly, open collector terminal (6) opens.
Every 22 hours, the microcontroller automatically performs the battery test, notified by LD4 fast flash and other tests
every 10 sec. In case of anomaly, LD4 LED blinks according to the table below.
If the sounder is
correctly powered
, the anomaly output (terminal no. 6)
usually stays at 0V
(current max 50mA). In
case a test performed
is not passed
, the anomaly output
disconnects from ground and becomes free
.
Notification of last anomaly, indicated by LED LD4 is reset to zero only if a command is given to terminal no.4 or c3.
To launch the remote battery test, send a pulse to terminal no. 5 with sounder on rest mode. This way, a 30-seconds
test runs.

FLASH RESET / BLOCK SPEAKER INPUT
With DIP6 in OFF, terminal 5 works as block speaker. With DIP6 in ON, terminal 5 works as reset flash: the flashing
unit activates with sounder trigger and deactivates with terminal 5. During normal operation, a command to terminal
5 activates battery test that lasts 30 seconds.
