Auxiliary Inputs/Outputs
AO1 SET TO MODE 02, ‘STATUS INDICATION’
When set to mode 02 auxiliary output AO1 is used exclusively as a monitoring input. For example, checking if a gate/door is open
or closed. Once set the AO1 input status can be interrorgated in two ways:
1. During a call:
press 9 on the telephone keypad and listen to the number of beeps in the ear piece. One beep indicates the input
is closed and two beeps indicates the input is open.
2. At anytime:
send the SMS message
1111CHK?
to the GSM PRO intercom. An SMS message will be returned with
IN=OP
for
open or with
IN=CL
for closed.
For this feature an additional relay will be required and the AO1 input must be wired as shown in
Fig.21
.

AO1 SET TO MODE 03, ‘DIVERT CALLS TO MASTER NUMBER’
It is possible to have all call buttons diverted to the master number outside certain hours or when auxiliary output AO1 has been
set to mode 03 (auxiliary output AO1 is used as a monitoring input). If there is no master number stored, the intercom will beep and
the busy LED will flash once to indicate no call is taking place (if the speech board is switched ON, this will announce “the phone is
switched off please try later”).
For this feature to work a time band must be setup and a master number stored (to setup the time band and store a master number
follow the SMS programming section on page 38 or the relevant steps in the GSMSK PC software manual). A switched common and
normally open (CO/NO) trigger needs to be used to enable or disable call divert to master number and the auxiliary output AO1
must be wired as shown in
Fig.22
