The XP95 Beam Detector is made up of three main parts: the transmitter, which projects a beam of infra-red light, the receiver, which registers the light and produces an electrical signal, and the interface, which processes the signal and generates alarm or fault signals.

The transmitter and receiver are designed to be fitted on opposite walls approximately 300mm to 600mm below the ceiling. They can protect areas up to 100m long and 15m wide.

If it is difficult to fit the transmitter and the receiver to opposite walls, they can also be fitted in retro mode, ie, adjacent to each other on the same wall. One or more reflectors need to be fitted to the opposite wall to reflect the beam from the transmitter to the receiver.
The XP95 Beam Detector is loop-powered, removing the need for a separate power supply. This minimises installation time and cost.
