The GSM backup option is a cost effective way for a dialer alarm to send a signal to the Monitoring Centre receivers in the event that the primary communications line is not operating. 

Line failures can occur for a number of reasons such as a deliberate action or severe storm damage.  By utilizing the GSM backup option, the ability of the alarm system to communicate in the event of a main line fail is increased.  The alarm system monitors the main line for connectivity, and when it is lost, the GSM can take over, allowing the continuation of vital alarm signals to be sent to the Monitoring Centre.

For the GSM backup unit to work effectively, it must be installed in an area that has good mobile coverage.  Consult your alarm installer for the best options on utilising the GSM backup option.  The system requires a SIM (Subscriber Identity Module) Card to operate and is the responsibility of the customer to maintain.

GSM coverage may not be available in all areas, and some environmental issues may also interfere with the GSM signal.  Consult with your alarm service provider to discuss a solution that best suits your needs.
