Monitoring

Monitored intruder alarm systems are connected to our Alarm Receiving Centre (ARC). This means that on activation of the alarm, a signal is sent to the ARC, via a telephone line and/or cellular network.
Where a police response is required, the monitored intruder alarm system must be capable of giving a confirmed alarm activation. This means that when a detection device is triggered and the alarm activated, the first signal will be sent to the ARC, who will notify the nominated Keyholder. If a second detection device is then triggered (e.g. a burglar moving from one area into another) a further signal will be sent to the ARC. This is classed as confirmation and the police response would then occur.
The various types of monitored systems are as follows:

Digital Communicator: In the event of an alarm activation, a signal is sent via a normal telephone line to the ARC. A nominated keyholder is then notified.
Note: If the telephone line is cut prior to the alarm activation, the signal to the ARC cannot be sent but the 'audible only' part of the system will still operate.

BT RedCare Classic: A constant signal from the alarm system to the ARC is sent over a RedCare enabled telephone line. RedCare continuously monitors the line and in the event of any disruption such as the line being cut, the ARC is notified and will contact the keyholder.

BT RedCare GSM and CSL Dualcom plus: Both these systems have two signaling paths - the radio and the telephone line. If both signal paths are lost, the ARC should receive two signals thus providing confirmation that the alarm is genuine. Furthermore, if only one of the two signaling paths is disrupted (e.g. line cut) the ARC is notified. The remaining path continues monitoring and in the event of an alarm activation, will send the signal to the ARC so that the necessary action can be taken.
