PIR OCCUPANCY SWITCHES

PIR OCCUPACY SWITCHES PIR occupancy switches The DAERS range of passive infra-red occupancy switches is designed for the automatic control of lighting, heating, ventilation or air conditioning s. The PIR switch will switch on the connected 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. PIR occupancy switches are ideal for: Offices Factories Warehouses Schools eisure centres Hospitals Canteens Staff rooms Corridors and stairwells Rential homes Military accommodation Student accommodation Toilet blocks Changing rooms Plus many other uses 6

PIR OCCUPACY SWITCHES PIR occupancy switch functions Each PIR occupancy switch in the DAERS range has a passive infra-red quad person detector. This detects the movement of a warm body moving within its detection zone. When such a movement is detected the is switched on. There is a time lag function which is adjusted using a spindle on the of the product. The time lag is the time that must elapse with no movement detected before the PIR occupancy switch will switch off. Simple adjustment spindles There is a built-in, adjustable, photocell override which can be used to keep lights off when there is sufficient daylight available. The photocell can only be used in this way if the amount of natural daylight exceeds the level of the artificial lights. The photocell can be set to inactive when controlling heating, ventilation or air conditioning. The photocell is also adjusted by a spindle on the of the product. Each PIR occupancy switch contains a relay suitable for switching any type of, including fluorescent lights and fans. A few PIR occupancy switches may be wired in parallel to control the same. However, there are minimum restrictions with the WAPIR model only (see page 19). The PIR occupancy switches require a mains supply. Function demonstrated with the lighting in an office PIR occupancy switch brings lights on only when needed Enough daylight, Occupied ighting OFF Enough daylight, Unoccupied ighting OFF ight, Occupied ighting O ight, Unoccupied ighting OFF 7

PIR OCCUPACY SWITCHES PIR occupancy switch specifications PIR detector Passive infra-red quad person detector. Adjustable time lag Time lag adjustable in 9 steps (approximate values): 10 seconds 1.25 minutes 10 minutes 20 seconds 2.5 minutes 20 minutes 40 seconds 5 minutes 40 minutes Adjustable photocell "Inhibit on" photocell. The photocell will inhibit the lights from switching on when somebody enters an area with plenty of ambient light. However, if somebody is already occupying an area with the lights switched on, the lights will remain on while the area is occupied, regardless of any increase in the ambient light level. This is to avoid any nuisance switching off when somebody is in the middle of a task or meeting. Range 100-1000 lux (and inactive), falling on the working plane. oading All models can switch up to 6 amps (1500W at 230VAC) of resistive, inductive or fluorescent lighting s, or up to 1amp (250W) of fans. For the WAPIR model there are some minimum requirements (details on page 19). Wiring in parallel A few PIR switches can be wired in parallel to control the same. Again for the WAPIR model there are some minimum requirements (details on page 19). Start-up Mode (Relevant to all models except WAPIR) When the mains supply is initially connected to the PIR occupancy switch it goes through its Start-up Mode. This means it switches on for about 1 minute, then switches off and enters its Operating Mode. If a manual wall switch is feeding the PIR occupancy switch (see wiring diagrams on appropriate product pages) then it will go through the Start-up Mode each time the wall switch is switched on. By wiring the manual wall switch in the alternative position, the supply to the PIR occupancy switch is uninterrupted and it remains in Operating Mode. It does not go through its Start-up Mode each time the wall switch is switched on. 8
