Dual Signalling


Dycon's dual signalling devices use a radio network as well as a telephone connection to transmit alarm signals at high speed using multiple signal paths ensuring that your alarm signalling will always have a back up path in the event of an accidental or deliberate fault on either path.

We have been in the forefront of dual signalling development and continue to lead the way using the latest technologies for up to date modern communications systems.

Dycon's dual signalling devices come in three different configurations:

GSM and PSTN signalling
GPRS and PSTN signalling
GPRS and PSTN signalling which connects to a control panel's PSTN connection. This enables Contact ID signalling to an Alarm Receiving Centre.
