GSM LineGuard Alarm Transmitter

The Bold Line Guard is a simple, easy-to-use communications device that can provide GSM back-up alarm signalling for existing digital communicators.

The LineGuard is the most cost-effective way of transforming existing digi-diallers into dual-path signalling devices.

In the event of a communications failure, the LineGuard sends a comms fail message to up to two mobile phones – perfect for alerting the security or facilities manager to the problem.

The LineGuard then ensures any further activations are transmitted using Contact ID or Fast Format to an alarm receiver in an ARC.

For example, if an intruder cuts the analogue telephone line, the LineGuard will signal the Intruder Alarm to the monitoring centre over the GSM network. The Pager uses a standard voice SIM card from any mobile network operator and with a minimal talk time tariff, provides a cost-effective dual-signalling solution.

With very minimal installation required, and full programming software provided, the LineGuard really is the easiest way to achieve dual-path signalling.
