System Operation
MAKING A CALL AND CANCELLING A CALL FROM THE GSM PRO INTERCOM TO THE PHONE
Press the required call button. Two beeps will be heard to
indicate the call has been placed, see Fig.87. 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,
see Fig.88.
If the speechboard is switched ON then the GSM PRO will
announce “calling please wait”.
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, see Fig.89. Both the busy and call LEDs
will switch OFF, see Fig.90.
If the speechboard is switched ON then the GSM PRO will
announce “call cancelled”.
IMPORTANT NOTE: 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 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 PRO INTERCOM
After answering the call the speak LED on the GSM PRO
will illuminate, see Fig.91. The speech will be open and a
conversation can take place.
While the speech is open the user can:
• release the door/gate (refer to notes further on);
• latch the door/gate (refer to notes further on);
• activate the auxiliary outputs AO1/AO2 (depending on
auxiliary mode setup, also see programming notes);
• adjust speech volumes to and from the GSM PRO.
Also refer to the user command tables on page 67.
To end the call hang up the phone and the speak LED will
switch OFF, see Fig.92.

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
First make a call from the GSM intercom, as described above. 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 PRO 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 PRO 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.
