In line with the ever-changing world of technology, CSL has designed a DualCom variant utilising GPRS (Packet Radio) as its encrypted primary signalling path. Combining this with IP (Internet Protocol) technology as the alternative path gives you a truly cost effective and secure approach to dual-signalling.

This exciting combination of technologies is generating an enthusiastic response from our industry.

From CSL's perspective, we designed DualCom GPRS/IP to satisfy the ever-growing demand for these technologies from the Retail sector in particular, where cost and performance are under constant scrutiny.

In the event of an alarm, DualCom's GPRS sends packets of data, via radio. The speed of transmission surpasses the older GSM technology, hence its suitability for sending alarm signals.
Rather than having to 'dial-up' for a connection, GPRS systems are permanently switched on and transmit instantaneously. Another popular feature of GPRS is its low operating costs. A flat rate is charged per month to cover all calls made and monitoring.

The IP path uses an TCP/IP connection to include compatibility with Broadband/WAN/LAN.
DualCom's IP path can either replace the PSTN path or be used in addition, creating up to three diverse routes on alarm transmission.

• 2 high-speed signalling paths


• No ARC chip programming required (plug and go)


• Automatically locks into ARC


• Low running costs


• Low installation costs


• Secure, encrypted packet data


• Convenient monthly billing to spread cost
