The automatic switching of lights, particularly when someone approaches a building, can be a useful deterrent to unwanted visitors as well as being convenient for welcome ones.

Suitable for both residential and commercial premises, the Halon Bank Light Control System is activated by movement detection and comprises three elements, the sensor head, drive unit and an optional control unit.

The passive infra-red sensor head can have either a 17m volumetric or a 30m long range. Both heads are fully adjustable to obtain optimum coverage. For extended coverage, up to 10 sensor heads can be connected to a single drive unit.

The drive unit containing the power and light switching electronics is waterproof and can be mounted either inside or out. It has a fixed 5 minute "light on" period with no user override.

For greater flexibility, a control unit can be added. This allows the user to select walk test, permanently on/off or automatic, which switches on lighting when the sensor is activated and ambient light levels are low. A chime option can be selected to inform users of approaching visitors. Adjustments can be made to daylight sensitivity and the "light on" period. The flush or surface mounted control unit is wired directly to the drive unit and does not require a mains supply, allowing it to be more conveniently positioned. Alternatively the light control system can be fully integrated with the Halon Bank Windsor CA500 intruder alarm control unit.
