Communications Connections

Cambridge based Briar Security Services offer three basic types of communications devices for connection to your intruder or fire alarm system: speech dialler, single signal path communicators and dual signal path communicators.

Speech Dialler

Designed for the domestic market, this plug-on device uses a conventional phone line. It can phone up to 4 pre-programmed telephone numbers, leaving a recorded message that an alarm is in progress.

Single signal path communicators

Digital Communicator: This device is connected to a conventional PSTN telephone line and dials the Alarm Receiving Centre (ARC) when any of its 8 programmed inputs are triggered.

RedCARE 'Classic': From your system, a RedCARE Subscriber Terminal Unit (STU) is connected to the ARC, via BT's RedCARE network. It incorporates a high security, multi path routing system, which ensures your signal gets through, even if part of the network is 'down'

Dual signal path communicators

To comply with BS DD:243 standards on confirmed activations for communicated systems, ensuring the capability of a police response on all signals (including line break/fault), a dual signalling device is required.

DualCom: The primary path uses a fixed radio device on the Vodaphone Data Network (VDN), which is monitored at regular intervals to ensure the device is 'in signal'.

RedCARE 'GSM': The RedCARE GSM Subscriber Terminal Unit (STU) is connected to the ARC via BT's RedCARE network utilising a fixed GSM mobile unit as the secondary path. It incorporates a high security, multi path routing system on both signal paths, which ensures your signal gets through, even if any part of either network is 'down'.
