ARMING/ DISARMING REMOTELY
Armed mode can be activated by short, free call. In order to switch the armed mode on, user calls
GsmAlarm-420 number and, hearing the first signal, cancels the call. In this case no switch-on delay
time is countdown. After the armed mode is on, user receives a short confirmation call or SMS.
Don’t cancel the confirmation call because it is cancelled automatically.
Switch the armed mode off by calling GsmAlarm-420 number and waiting for the system cancels the
call (3-4 call signals).
Check whether the alarm is operating by short call to GsmAlarm-420 number. If GsmAlarm-420 is in
operation, user receives a short confirmation call.
7.3.
CONTROL USING DTMF AND SMS INSTRUCTIONS
In the speech mode user can control the system, after having entered relevant code from his phone
keyboard. Instruction consists of two digits, it is entered by pressing asterisk key. If the instruction is
completed, user hears three tone confirmation signals. If given instruction has already been executed
earlier (e.g. you want to switch on the commutator, that is already ON), user hears one tone
confirming signal.
Speech mode can be activated in two ways: user answers when GsmAlarm-420 calls, or user calls
and waits for GsmAlarm-420 to answer (3-4 call signals). In this case relevant parameter F has to be
programmed (see Ch. 5.3.2.3), otherwise, after 3-4 calling signals, the arming mode will be switched
off and the call will be cancelled.
The control instructions may be given by SMS. Insert password in the beginning, then type the
instruction. E.g., in order to switch on commutator C1, to switch off commutator C2, to switch on
BELL and to receive a SMS with information on the status of the protected site, send the following
SMS:
