System Operation
MAKING A CALL AND CANCELLING A CALL FROM THE GSM INTERCOM TO THE PHONE
1. To place a call press the desired call button. Two beeps will be heard from the GSM module to indicate the call has been placed.
2. The busy LED will switch ON then OFF and the call LED will illuminate to indicate that the system is engaged and a call is in
progress. If the internal speechboard is switched ON then the GSM intercom will announce “calling please wait”.
3. 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. Both the busy and call LEDs will switch OFF.
4. If the internal speechboard is switched ON then the GSM intercom will announce “call cancelled”.
IMPORTANT NOTE: If the silent dialling mode feature, AUE, has been left on default (i.e. silent dialling mode enabled) 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 INTERCOM
1. After answering an incoming call the speak LED on the GSM intercom will illuminate. The speech will be open and a conversation
can take place. While the speech is open the user can:
• release the door/gate (also see notes releasing the door/gate from the phone after a call from the GSM intercom).
• latch the door/gate (also see notes releasing the door/gate from the phone after a call from the GSM intercom).
• activate the auxiliary outputs AO1/AO2 (depending on auxiliary mode setup, also refer to programming notes).
• adjust speech volumes to and from the GSM intercom.
Also refer to the user command tables on page 71.
2. To end the call hang up the phone and the speak LED will switch OFF.
IMPORTANT NOTE: The busy LED will switch ON then OFF at the beginning of the call and again will switch ON then OFF at the
end of the call when either the user hangs up the phone or if the call time SPT expires.
DIVERTED CALL
1. First make a call from the GSM intercom, as described above.
2. If any divert numbers are programmed and the primary number is not answered the GSM will then dial the divert number(s)
after the programmed divert time DIT has elapsed (also refer to STD, STE and STF divert number programming and DIT divert
time setup in the programming section of this manual).
IMPORTANT NOTE: When the GSM intercom diverts to a programmed divert number there will be a brief pause before the
intercom then proceeds to dial the divert number. If the speechboard is switched ON the GSM will also announce “please wait”,
this is normal behaviour from the GSM module. Also if the silent dialling mode AUE has been left on default (i.e. silent dialling
mode enabled) 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 INTERCOM INC. LATCH/UNLATCH
Releasing the door/gate is signalled by 1 second interval beeps from the GSM intercom panel.
1. After the call is answered and the speak LED illuminates, pressing 3 on the phone releases the door/gate for the programmed
relay time and the door open LED will switch ON.
2. If the internal speechboard is switched ON then the GSM will announce “the gate is open” or “the door is open”.
3. 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 intercom).
Also refer to the user command tables on page 71.
RELEASING THE DOOR/GATE BY DIALLING THE GSM INTERCOM DIAL TO OPEN
1. Releasing the door/gate by dialling into the GSM 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).
2. Simply dial the mobile number of the SIM in the GSM intercom. The GSM intercom will recognise the stored dial to open
number that’s calling, the busy and door open LED’s will switch ON. The GSM will drop the call and open the door/gate for the
programmed relay RLT time, after the relay time has elapsed both the busy and door open LED’s will switch OFF.
3. If the internal speechboard is switched ON then the GSM will announce “the gate is open” or “the door is open”.
IMPORTANT NOTE: For this function to operate correctly the stored DTO number must have any “caller ID” or “withheld number”
feature switched OFF. If this is not switched OFF on the number making the call to the GSM intercom then the GSM module will
not recognise the caller’s number and simply drop the call and the door/gate will not operate.
