DUAL COM (CSL)
DualCom is a totally integrated dual-signalling device using both telephone and radio paths. This combination ensures an alarm signal can be transmitted despite deliberate or accidental failure of either path.
Since its introduction to the Intruder Alarm market in 1996, DualCom is officially recognised as the original and most widely used dual-signalling device in the UK. It's reputation as an advanced, reliable and cost effective signalling device has led to nationwide installations in supermarket chains, high street stores, banks and other vulnerable premises. DualCom is compatible with any cable telephone network and uses the Vodafone Packet Radio Service (VPRS) to transmit signals within seconds.
Before installing DualCom signal strength tests would be carried out to ensure sufficient signal strength in your area for the radio Packet path. In circumstances where this is weak DualCom GSM may be considered in place of standard DualCom
As with both the Digital Communicator and Redcare the DualCom signals to an ARC (Alarm Receiving Centre) who in turn monitor and action all signals received to the relevant Police Authority and key-holders.
