3.4.3
External horn
The grey wire can be connected to an external horn.
This might be useful, if the internal buzzer cannot be heard for some
reason.
When the internal buzzer turns on, this wire has got the supply voltage
+12 V or +24 V (up t0 4 A can be drained).
All type of alarms are duplicated from the internal buzzer.
3.4.4
Auto Dial-up
Valid with Firmware >= 0.0.4
With the Auto Dial-up function you can trigger an Auto-Dial device to
send a text message or do a phone call to pre-saved numbers.
With receiving an AIS SART/MOB the grey wire is set to + power supply
voltage for four minutes.
If you press the “Mute SART Alarm” push button, the output is also
muted.
This means that this button also prevents a new Dial-up for 30 minutes.
When you don´t mute the unit you´ll hear a SOS Morse sounding
(. . . - - . . .) every time a SART/MOB telegram is received. After four
minutes the Auto Dial-up output is being switched off.
When still receiving an AIS SART/MOB signal the next 4 minutes interval
is triggered.
As long as this output is active, the time is not retriggered.
