The Surfguard has been developed as a safety system to detect intruders on the top of a lift car. On detection of an intruder, the unit provides an output that can be used to stop the lift running. In addition, outputs are provided to operate a beacon and siren. An auxiliary output is also available for remote alarm indication.

The Surfguard is a dual passive infra-red detector system, which provides an horizontal and vertical field of view on the car top area. It is sensitive to changing thermal images and it will detect a person attempting to jump onto the car top. There is also a vertical sensor wired into the horizontal detector to sense any object being thrown over the detection devices from above.

• Greatly reduces the risk of accidents
• Deters intruders
• Quick and easy to fit to any type of lift
