System Operation
MAKING A CALL AND CANCELLING A CALL FROM THE GSM LITE INTERCOM TO THE PHONE
Press the required call button. Two beeps will be heard from the GSM LITE intercom to indicate the call has been placed.
If a mistake is made, simply press any other button to cancel the call, a long beep will be heard to conrm the call has been cancelled.
IMPORTANT NOTE: If the silent dialling mode AUE has been left on default (i.e. silent dialling mode disabled) a normal telephone
dial tone will be heard through the GSM’s speaker after the call button has been pressed to indicate that the number is being
called. If the same button is pressed again after ve seconds of placing the initial call this will also cancel the call. Pressing the
same button before the ve seconds is up will do nothing.
ANSWERING AND ENDING A CALL FROM THE GSM LITE INTERCOM
After answering the call the speech will be open and a conversation can take place. While the speech is open the user can:
• release the door/gate (see notes below).
• latch the door/gate (see notes below).
• activate the auxiliary output AO1 (depending on auxiliary mode setup, also see programming notes).
• adjust speech volumes to and from the GSM LITE.
Also refer to the user command tables on page 43.
To end the call simply hang up the phone.
DIVERTED CALL
First make a call from the GSM intercom, as described above. If a divert number is programmed and the primary number is not
answered the GSM will then dial the divert number after the programmed divert time DIT has elapsed (also refer to STD divert
number programming and DIT divert time setup in the programming section of this manual).
IMPORTANT NOTE: When the GSM LITE intercom diverts to a programmed divert number there will be a brief pause before
the intercom then proceeds to dial the divert number. Also if the silent dialling mode AUE has been left on default (i.e. silent
dialling mode disabled) a normal telephone dial tone will be heard from the GSM’s speaker after the brief pause to indicate that
the divert number is being called.
RELEASING THE DOOR/GATE FROM THE PHONE AFTER A CALL FROM THE GSM LITE INTERCOM INC. LATCH/UNLATCH
Releasing the door/gate is signalled by 1 second interval beeps from the GSM LITE intercom panel.
After the call is answered pressing 3 on the phone releases the door/gate for the programmed relay time.
Pressing 1 followed by 0 will latch the door/gate in the open position (to unlatch press 3 and the door/gate will unlatch or send text
message 1111RUL to the GSM LITE intercom).
Also refer to the user command tables on page 43.
RELEASING THE DOOR/GATE BY DIALLING THE GSM LITE INTERCOM DIAL TO OPEN
Releasing the door/gate by dialling into the GSM LITE using the dial to open DTO number is only possible if the caller’s number has
been stored correctly using the STR programming command (also refer to STR programming notes for correct setup).
Simply dial the mobile number of the SIM in the GSM LITE intercom. The GSM intercom will recognise the stored dial to open
number that’s calling. The GSM will drop the call and open the door/gate for the programmed relay RLT time.
IMPORTANT NOTE: For this function to operate correctly the stored DTO number must have any “caller ID” or “witheld number”
feature switched OFF. If this is not switched OFF on the number making the call to the GSM LITE intercom then the GSM module
will not recognise the caller’s number and simply drop the call and the door/gate will not operate.
