GSM Intercom Systems

GSM systems are a very cost-effective SIM-card based access control entry solution that employs quad-band mobile phone technology to communicate with and operate automatic gates, doors, and remote site applications.

When a button is pressed on the external panel of our GSM systems, at the main gate, front entrance door or communal door to a block of flats, the intercom station is set up to use a SIM card to make calls. This will then call all pre-defined telephone number(s) of the occupant. If the call is not answered after a predetermined amount of time, the system may then attempt to call telephone numbers of other occupants sequentially, if required.

Another incredible feature of our GSM intercom systems is their ability to provide keyless entry, simply by phoning the intercom. The feature works by means of a white-list feature, where you call the phone number of the SIM card in the GSM Intercom. The intercom system then recognises your telephone number from its list of authorised numbers, triggering the intercom to unlock the door for you.

Systems come complete with various optional accessories such as Hearing Loops, proximity tag readers and keypads, to suit all requirements.

How the GSM system works

Call the GSM Key from your phone. It checks your caller ID and as you are authorised the GSM Key triggers your door to open. Alternatively, you can send a text message to the GSM Key to Open/Close the door or operate any other electrical equipment.
