Programming the GSM Intercom
is open or closed. See example, Fig.28, on page 24.
Divert Calls to Master Number: nn = 03
When in this mode, the AO1 terminal is used exclusively for monitoring the status of a switched input to decide if calls should be
diverted to the master number or not. See example, Fig.29, on page 25.
Call Activate (Timed): nn = 04
AO1 output will activate when a call begins and deactivate when the auxiliary 1 output time (A1T) expires. See example, Fig.30, on
page 25.
Enable/Disable “Dial to Open”: nn = 05
When in this mode, the AO1 terminal is used to enable/disable the dial to open feature via an external C/NO switched input across
terminals AO1 & g, (for example the C/NO relay contacts on a timeclock could be connected across terminals AO1 & g on the GSM
intercom. When the timeclock relay is ON then no dial to open numbers are allowed. The GSM answers the call and awaits the
master code to be entered. When the timeclock relay is OFF all DTO numbers will operate as normal). See Fig.31, on page 25.
1111A1Mnn Store the AO1 mode nn = 00 - 05.
1111A1Mnn? Store the AO1 mode nn = 00 - 05. Also send a conrmation text back to the sender.
1111A1M? Query the stored AO1 mode. A text will be sent back to the sender showing the stored A1O mode.
SET AUXILIARY OUTPUT AO2 TIME A2T
The auxiliary output AO2 time can be set from 01 - 99 seconds or latching (set the AO2 output time to 00 for latched mode. In latch
mode the AO2 output will stay triggered until the relevant command is sent again to unlatch the AO2 output).
1111A2Tnn Store the AO2 time nn = time in seconds (e.g. nn = 05, time = 5 seconds).
1111A2Tnn? Store the AO2 time nn = time in seconds. Also send a conrmation text back to the sender.
1111A2T? Query the current stored AO2 time. A text message will be sent back to the sender showing the
stored AO2 time.
DIVERT TIME DIT
The divert time is the number of seconds to wait for a call to be answered before diverting to the 2nd, 3rd and 4th number. The
default time is 15 seconds (the count down begins from when the call button is pressed, but is refreshed when the telephone
begins to ring) and can be set from 01 – 99 seconds.
1111DITnn Store the divert time nn = time in seconds (e.g. nn = 15, time = 15 seconds).
1111DITnn? Store the divert time nn = time in seconds. Also send a conrmation text back to the sender.
1111DIT? Query the current stored divert time. A text message will be sent back to the sender showing the
stored divert time.
CHECK SIGNAL STRENGTH SIG
At any time the signal strength of the GSM can be checked (also see notes understanding the signal strength on page 72). It is
advisable that when the GSM is rst setup and before any other programming is carried out to check the signal strength of the GSM
intercom. If the signal strength is too low the GSM intercom may not operate properly and therefore the GSM antenna will need to
be repositioned to increase the signal strength. Use the following command to check the signal strength.
1111SIG? Check the signal strength of the GSM intercom and send a conrmation text back to the sender.
CHECK SOFTWARE VERSION VER
It is possible to check the current version of software on the GSM intercom. This may be necessary to see if an update is required for
any additional features or updates on the GSM intercom which may be included on later versions. Use the following command to
check the software version.
1111VER? Check the software version of the GSM intercom and send a conrmation text back to the sender.
FORCED DIAL/DIAL A NUMBER DLE
A useful feature of the GSM intercom is its ability to call a number sent to it in a text message. This feature can be used when setting
up the SIM card. For example, disabling the voicemail facility or disabling automatic SMS messages or missed calls. Any number up
to 15 digits can be called and the call will last for a maximum of 40 seconds. The example below would switch OFF voicemail on a
Vodafone SIM card. Substitute the Vodafone number for other service providers.
1111DLE”1210” Dial 1210 for the intercom panel.
Other useful numbers which can be used with this feature are as follows. Please also check the network service provider’s web sites
for other useful codes.
