Choose from a range of systems, ranging from basic protection to highly sophisticated solutions so that your Monitored Intruder Alarm is equipped to deter and protect for total peace of mind:

Single Path Monitoring

A single path signalling system can dial out using either the GSM mobile network, GPRS mobile data network or a fixed phone line. It can also send more sophisticated information to the ARC. Single Path Monitoring can report the type of breach, such as a personal attack or standard alarm activation, including the zone triggered within the property.

Dual Path Monitoring

Dual path signalling systems do everything that a single path system does but in addition if there's a fault or problem with the primary channel, such as a fixed line - they will automatically use the back-up channel, such as the GSM mobile network.

Smoke Device

Most property loss occurs in the initial minutes of a break-in. Install a smoke device on the premises and within seconds of a break-in the protected area is filled with an impenetrable cloud of fog.

This provides an effective barrier and forces the intruders to leave the premises.
