The Danlers range of Passive Infra-Red occupancy switches is designed for the automatic control of lighting, heating, ventilation or air conditioning loads.
The PIR switch will switch on the connected load automatically when an area is occupied, and then switch it off automatically when the area has been vacant for a chosen duration. This has the benefits of reduced energy bills and automatic control. When being used to control lighting, the built-in photocell can be used to keep the lights off on bright days.
These directional PIR switches plug into a ceiling mounted socket. These sockets can be mounted on a BESA box. Designed to give a directional view of the activity to be monitored. Suitable for corridors and storage aisles.
The CESF PIR is a hard wired Ceiling Surface Mount PIR switch which can be mounted on a square pattress box. These surface-mounted models are ideal for solid ceilings. Designed for switching lights on when an area is occupied and then off when area is vacant for chosen duration.
The WACE PIR is suitable for either wall or ceiling mounting. It fits either into a plaster depth (16mm) wall box or onto a ceiling mounted square pattress box. It requires a neutral wire. Suitable for stairwells, corridors, toilet, lobbies etc.
