ALARM FUNCTION
An alarm device (Normally Closed contact) can be branched between pin 4 and 5 of the ADV terminal board
of the receiver. If the alarm triggers (the contact opens), the gsm module will send an alarm signal to the cell
phone numbersenabled for this function.
The warning signal consists in a phone call to the rst number stored in memory and enabled for this func-
tion (the order is determined by the memorisation order of the numbers in the SIM memory). The one who
receives the telephone call can disconnect the call and the alarm will stop. Otherwise, after 30 seconds, the
call will be disconnected and the second number enabled will be called, and so on.
Note: to stop the alarm by disconnecting the telephone call, the cell phone must have the telephone an-
swering function disabled.
To enable the telephone number for the receipt of the alarm signal, send the following command “adda-
larmnum” as described hereunder:
addalarmnum 123456 +NN3391234567,+NN3391234568,+NN3391234569 etc
where:
addalarmnum command string
123456 access password
+NN3391234567 telephone number with international code*, if more than one number must
be typed in with one single message, it is sucient to separate the numbers
with “,”
the number +NN3391234567 (and following) will be called if an alarm occurs
*In this case, the international code must be entered so that the alarm call can reach the user even if he is
in a foreign country, different from the country in which the CALL device is installed.
Any number can be reached by an alarm signal.
If the number is already stored in memory, it must be in any case re-entered with the addalarmnum func-
tion.
To erase the telephone number from the list of enabled numbers for alarm, use the delnum function.
In this way, the number will be erased. The corresponding number, added with the addnum function, will
be erased as well.
When the red LED of the gsm module triggers, it switches on with xed light and it will switch off when so-
meone disconnects the call or when all listed numbers have been called.
