ALARM FUNCTION
An alarm device (normally closed device) can be connected between Pin 4 and 5 of the ADV terminal board.
If the alarm triggers (the contact opens) the GSM module sends an alarm message to the mobile phone
numbers enabled for this function.
The message consists in a telephone call to the rst number in memory enabled for this function (the order
is determined by the memorisation order in the SIM card). Whoever receives the call will be cable to hang up
and the alarm message will stop. Conversely, the call will stop automatically ad the second enabled number
will be called after 30 seconds, and so on.
Note: in order to be able to stop the alarm by hanging up, the mobile phone must have the telephone sec-
retary function disabled.
The command “modnum” allows for the entering of a phone number to receive the alarm message. In this
case, the number 1 must be typed in the rst digit of the presetting string, for example:
modnum 112233 1XXXXX +NN3391234567
the number +NN3391234567 will be called in the event of alarm
modnum 112233 0XXXXX +NN3391234567
the number +NN3391234567 will not be called in the event of alarm
When the alarm triggers, the red LED of the GSM module switches on with xed light and switches off
when someone cuts the call or when all phones have been called and the search of numbers to be called
completed
WARNINGS
When entering the customized password (modpsw) and when customising the command strings (setcm-
dmsg), it is important not to leave blank spaces unintentionally.
The system, in fact, considers spaces as actual digits so that password “ABCDEFG ” differs from “ABC-
DEFG” as the rst password features a blank at end of string.
For the same reason, when entering the various phone numbers for enable, disable purposes, etc., it is
important not to leave blank spaces between the various numbers, for ex.:
addnum 112233 +NN3391234567,+NN3391234568,+NN33912345679
is correct at the phone numbers are separated by a comma only.
while
addnum 112233 +NN3391234567, +NN3391234568, +NN33912345679
is incorrect and only the rst number will be stored in memory.
