The digital communicator utilises your existing telephone line or a separate telephone line to send signals to the Alarm Reciving Centre (ARC). The communicator can send different types of signal depending on the situation, such as a personal attack alarm in the event of a hold up device being activated. The Alarm Receiving Centre (ARC) will then take the appropriate action for the signal received.

The digital communicator provides local identification of a failure with the telephone line on the control and indicating equipment at the premises, but it is not possible to alert the Alarm Receiving Centre (ARC) that the premiss' are no longer in communications.

So there for it is not a secure monitored linkback to the Alarm Receiving Centre.

This is a great way to monitor single path grade 2 risk buildings.
