How reliable is the signalling to the monitoring centre?

Your installer can offer you a choice of alarm transmission systems (ATS) to pass alarm and fault signals to the ARC. Your installer can explain the available options to you.

‘Dual path’ signalling is more resilient than ‘single path’. Insurers generally prefer it since it is unlikely that both paths will fail at the same time.

Dual path ATS solutions usually have an all-inclusive package for transmitting data so there are no ‘pay-as-you-go’ individual call charges.

Typically a dual path system includes a cable connection to the PSTN or IP network and a radio connection to a mobile network.

The radio connection might use GSM (cellular phone technology) or GPRS (General Packet Radio Service) transmissions. Some radio solutions connect to a single provider whereas other solutions might include a roaming SIM to enable connection to the best available service.
