Programming the GSM Intercom
1111BAL?
Check current balance of the SIM in the GSM LITE intercom and send a confirmation text
back to the sender.
In addition to this feature the GSM LITE intercom also has the facility to monitor the available credit and then text the user to inform
them when the credit has fallen below £5.00, €5.00 or $5.00. It will then remind the user with another text after every 5 calls until
the credit has either increased or if it runs out. To use this feature, the following settings must first be made:
• A Pay As You Go SIM card from a provider that offers this service (Vodafone, O2) must be used.
• The correct balance check string must be stored using the
SDL
code (see store balance check dial string).
• A mobile phone number that is to receive the ‘balance low’ text must be stored in the master telephone number location
using the STM code (refer to ‘store master telephone number’ feature below).
STORE THE MASTER TELEPHONE NUMBER (STM)
The master telephone number is the number which will receive automatic balance updates when the balance gets low (if this
feature is setup) and will receive the SMS message if auxiliary input 2 is triggered (also refer to example on page 21,
Fig.22
). To store
a master telephone number the following programming texts can be sent to the GSM LITE intercom.
1111STM”yyyyyyyyyyy”
Store the telephone number yyyyyyyyyyy.
1111STM”yyyyyyyyyyy”?
Store the telephone number yyyyyyyyyyy and send a confirmation text back to the sender.
1111STM?
Query the master telephone number stored. A text message will be sent to the sender with the
stored number for that location.
1111STM””
Delete the master telephone number stored.
1111STM””?
Delete the master telephone number stored and send a confirmation text back to the
sender.
LATCH THE RELAY (RLA)
It is also possible to latch the GSM intercom relay closed. This function is particularly useful if the GSM intercom relay is connected
to a gate controller (via an Art.120 pcb, refer to
Fig.13
, page 15) and the user wishes to ‘hold open’ the gate. The following text
message can be sent to the GSM LITE intercom.
1111RLA
Latch the GSM LITE relay to the C/NO position.
1111RLA?
Latch the GSM LITE relay to the C/NO position and send a confirmation text back to the
sender.
UNLATCH THE RELAY (RUL)
If the GSM LITE’s relay has been latched it is possible to unlatch the relay with the following text message.
1111RUL
Unlatch the GSM LITE relay back to the C/NC position.
1111RUL?
Latch the GSM LITE relay to the C/NC position and send a confirmation text back to the
sender.
IMPORTANT NOTE: The GSM LITE’s relay can also be unlatched by pressing 3 on the telephone during a call, unless the LLA
feature has been enabled (also see LLA program notes on page 41).
LATCH AUXILIARY OUTPUT AO1 (A1L)
Auxiliary output AO1, like the onboard relay, can be latched. To latch auxiliary output AO1 the following text message can be sent
to the GSM LITE intercom.
1111A1L
Latch auxiliary output AO1.
1111A1L?
Latch auxiliary output AO1 and send a confirmation text back to the sender.
UNLATCH AUXILIARY OUTPUT AO1 (A1U)

LITE intercom.
1111A1U
Unlatch auxiliary output AO1.
1111A1U?
Unlatch auxiliary output AO1 and send a confirmation text back to the sender.
CHECK INPUT STATUS (CHK)
IMPORTANT NOTE: This feature is only applicable when auxiliary output AO1 mode has been set to mode 02. If auxiliary output
AO1 is set to any other mode then this feature will not work (also refer to Fig.18 on page 19 and setting auxiliary output AO1
mode, A1M, on page 33).
If the auxiliary output
A1M
mode has been set to mode
02
then the status of this mode can be checked by sending the following
text to the GSM LITE intercom.
