PIR OCCUPANCY SWITCHESPIR occupancy switchesThe DANLERS range of passive infra-red occupancy switches is designed for theautomatic 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 tocontrol lighting, the built-in photocell can be used to keep the lights off on bright days.PIR occupancy switches are ideal for:• Offices• Factories• Warehouses• Schools• Leisure centres• Hospitals• Canteens• Staff rooms• Corridors and stairwells• Residential homes• Military accommodation• Student accommodation• Toilet blocks• Changing rooms• Plus many other usesPIR occupancy switch variantsSpecial variants of products are available on request such as 24V (a.c. or d.c.) versionsof our PIR occupancy switches and photocell switches, ideal for low voltage controlsystems. 12V variants can also be supplied. Some variants are available from stock fornext day delivery. To special order we can also supply volt free outputs for mains, 24V or12V supplies (including versions with gold relays).6
PIR OCCUPANCY SWITCHESPIR occupancy switch functionsEach PIR occupancy switch in the DANLERS range has a passive infra-red quad persondetector (except COPD and BMPIR which have a passive infra-red dual person detector).This detects the movement of a warm body moving within its detection zone. When sucha movement is detected the load is switched on. There is a time lag function which isadjusted using a spindle on the side of the product. The time lag is the time that mustelapse with no movement detected before the PIR occupancy switch will switch off.Simple adjustment spindlesThere is a built-in, adjustable, photocell override which can be used to keep lights offwhen there is sufficient daylight available. The photocell can only be used in this way ifthe amount of natural daylight exceeds the level of the artificial lights. The photocell canbe set to inactive when controlling heating, ventilation or air conditioning. The photocell isalso adjusted by a spindle on the side of the product.Each PIR occupancy switch contains a relay suitable for switching any type of load,including fluorescent lights and fans.A few PIR occupancy switches may be wired in parallel to control the same load.However, there are minimum load restrictions with the WAPIR model only (see page 21).The PIR occupancy switches require a mains supply.Function demonstrated with the lighting in an officePIR occupancy switch brings lights on – only when neededEnough daylight, Occupied –Lighting OFFEnough daylight, Unoccupied –Lighting OFFNight, Occupied –Lighting ONNight, Unoccupied –Lighting OFF7
