DualCom GPRS
Overview
DualCom GPRS is an advanced communication device for secure alarm reporting, compliant to Grade 2, 3 and 4 of the EN standards. It transmits alarm signals to the aim ARC via the GPRS, GSM and PSTN networks . Plus by using the optional LAN card, via the internet.
When DualCom GPRS is triggered it initiates calls to the aim ARC over all available communication paths. Once it receives an acknowledgement from one path it clears the other paths so that we only receive one notification. 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.
If enabled the IP path uses a TCP/IP connection to include compatibility with Broadband/WAN/LAN. DualCom IP can either replace the PSTN path or be used in addition, creating up to three diverse routes on alarm transmission.
As with all radio transmission systems, a site survey should always be carried out to ensure adequate GPRS signal strength is available at the site. Alternatively a Vodafone GSM phone can give an indication of the signal strength at the site.
The unit is ordered via aim administration and is delivered to you fully programmed and ready for immediate connection.
