AO1 = MODE 03, ‘DIVERT CALLS TO MASTER NUMBER’
It is possible to have the GSM call buttons diverted to the master
number (outside certain hours) using the TBA timeband feature
(refer to timeband TBA programming notes on page 47).
Alternatively it is possible to divert the GSM call buttons to
the master number when auxiliary output AO1 has been set
to mode 03 (like mode 02 the auxiliary output AO1 is used as a
monitoring input).
In this instance a switched common and normally open (CO/
NO) trigger is required to enable or disable the divert calls to
master number feature and the auxiliary output AO1 must be
wired as shown in Fig.29.
In either case a master number is required following the STM
store master number feature (see STM programming notes on
page 46). If no master number is stored, the intercom will beep
and the busy LED will ash once to indicate no call is taking
place (if the speech board is switched ON, the GSM module will
announce “the phone is switched o please try later”).

AO1 = MODE 04, ‘CALL ACTIVATED TIMED’
Similar to mode 00, however, when set to mode 04 auxiliary
output AO1 will activate when the call begins and deactivate
when the auxiliary AO1 time expires, see Fig.30.
The auxiliary output AO1 time can be set using the SMS
programming code 1111A1Tnn? (where nn = time in seconds,
refer to A1T programming notes on page 43) or setup by using
the GSMSK PC programming software.

AO1 = MODE 05, ‘ENABLE/DISABLE DIAL TO OPEN NUMBERS’
When the auxiliary output AO1 mode is set to 05 the dial to
open numbers will only activate the GSM relay when a common
and normally open (CO/NO) switch connected across terminals
g & AO1, as shown in Fig.31, is open circuit.
When the switch is closed and terminals g & AO1 are short
together this will disable the dial to open numbers.
