Programming the GSM Intercom
1111BAL? Check current balance of the SIM in the GSM unit, send a conrmation text back to the sender.
In addition to this feature the GSM 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.

A Pay As You Go SIM card from a provider that oers this service (e.g. Vodafone, O

The correct balance check string must be stored using the SDL code (see store balance check dial string notes).
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).

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 26, Fig.33). To store
a master telephone number the following programming texts can be sent to the GSM intercom.
