Ask A Question

This Danlers ceiling flush passive infra-red occupancy switch (PIR) can be flush mounted into suspended and plasterboard ceilings.

It includes a 2 metre connecting flex to make installation quicker and easier.

These neat and unobtrusive models are ideal for flush mounting through suspended or plasterboard ceilings. They have a 2m cable, for quick installation.

  • These PIR switches incorporate a passive infrared quad sensor to detect movement of a warm body within their detection zone and a photocell to monitor the ambient light level.
  • Upon detecting movement, if the ambient light is dark enough, the PIR switch will turn the load on.
  • The ambient threshold can be set by the user to between approximately 100 lux and infinite lux (photocell inactive) via the LUX adjuster.
  • If no more movement is detected within a pre-selected time, then the PIR switch will turn the load off.
  • This time lag can be set via the TIME adjuster to 10 seconds, 20s, 40s, 1 minute 15 seconds, 2m30s, 5m, 10m, 20m or 40 minutes.

Passive Infrared Sensors (PIRs) for Lighting, Ventilation, and Heating

The PIR - Passive Infrared Sensor - is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view and then trigger a certain action in a device or light fitting. They are most often used in PIR-based motion detectors, and they work in conjunction with lights, heating, ventilation, etc. Their main purpose is detecting the presence (or absence) of a human being (or a pet) in a certain area, and then switching ON or OFF the light, the fan, or the heat. The PIRs are of different kinds depending on the lighting loads, location (indoor or outdoor, wall or ceiling), IP rating, usage, etc. Some PIRs are integrated with the fitting: some light fittings come complete with a PIR sensor, and some fans have a PIR integrated for presence or motion detection. On our website at www.sparksdirect.co.uk we have quite a large range of PIR sensors - the standalone units - to help you save energy and make sure you don't waste money just because you forgot to turn the light or the fan off. Ceiling or Wall PIR Detectors from CP Electronics CP Electronics has quite a wide range of PIRs. One of them is the batten mount PIR, a miniature PIR that has been specifically engineered for mounting directly onto a batten style luminaire (see EBMPIR-MB), while another one is a retrofit PIR that allows previously uncontrolled lighting sources to benefit from presence detection and lux level (see EBMINT); these are both ceiling mounted PIRs. For ceiling flush mounting CP Electronics has the GEFL PIR movement sensor that provides automatic control of lighting, heating, or ventilation loads, having a low profile and being almost un-noticeable on the ceiling.If you prefer a wall-mounted PIR, the PDS-PRM no neutral wall mounted presence detector combines the PIR presence detection with a time delay function - it ideally replaces a wall switch so that, when the presence of a person is detected, the light turns on automatically. PIR Occupancy Switches from Danlers The Danlers range of passive PIR infra-red occupancy switches is designed for the automatic control of lighting, heating, ventilation or air conditioning loads. How it works: 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. Among the most popular ceiling flush PIRs from Danlers are the CEFL PIR (ideal for false or plasterboard ceilings) and the CEFL Sealed version (ideal for bathrooms and damp areas, sealed bathroom version). They also provide a wide range of batten mounted PIRs with the new "intelligent" photocell and a range of 5-10m detection; they are cost-effective solutions. Furthermore, they have some ceiling directional PIRs (which can be rotated and lowered, ideal for corridors and aisles), wall PIR detectors, and even some PIR occupancy switch modules (ideal for building into luminaires and for wall/ceiling mounting). Other PIRs: mini PIR, Outdoor PIRs, and Integrated PIRs Besides these two main British Manufacturers of PIR detectors and sensors there are many others, such as the outdoor BB2002 black outdoor wall-mounted PIR (up to 2000W, covers approx. 10m range, can be manually operated) and the BB3027 (2000W black PIR for corner-mounting outdoor, 270 degrees, 10m coverage). For indoor lighting control and with a £1 size is the BEG Luxomat PD9 - circular detection area, ceiling mounted or directly built-in lamps, or the ceiling mounted PD3FC circular mini occupancy detector which can be remotely controlled. For small spaces such as wardrobe lighting you can always use the LEDPC in-line photocell for LED striplights or the PIRSENSO mini PIR motion sensor for switching ON/OFF the lights up to 250W (10 sec - 3 mins PIR cupboard switch). The choice is yours: where and for what do you need a presence detector? Is it for indoor or outdoor? Is it for LED lamps, fluorescent fittings, or regular halogen or incandescent lamps? Take a look at the PIR solutions we at Sparks can offer you, and let us know if you need more information!

Danlers is Helping You Select the Appropriate PIR Occupancy Switch

Winners of the Queen's Awards for Enterprise for Innovation in 2010, Danlers Ltd is a family-owned UK company which designed and manufactured electronic energy-saving lighting controls for the past 20 years or so. Their R&D team is continually working on developing next-generation products in the lighting control industry, facing the well-known challenge of the influx of newer technologies of LED lights and other digital technologies. Tony Kay (the executive chairman) says, DANLERS commitment to reliability, simplicity and our UK manufacturing heritage is at the heart of why customers like our products. Helping You Select the Right PIR Switch If you browse our website or any online store with PIR switches, you tend to either be confused or not be clear about which switch you need. We apologize for the inconvenience of not yet having a precise page where we can present the below information, but for now we would like to at least post on our blog some ideas and information that may help you choose the right PIR occupancy switch. It is very important to consult with your electrician, first of all, and secondly to know what you're buying. Here are some categories or criteria of choosing a PIR occupancy switch: Ceiling Mounted PIR Switches with 360 degrees Detection Zone As per the diagram above, Danlers has a wide range of ceiling-mounted PIR occupancy switches which have a 360-degree detection zone. They can be either flush mounted (in false ceilings or plasterboard ceilings), or surface mounted (having a small projection from the ceiling). Also, they can be hard wired or plug & socket. Ceiling Mounted PIR Switches with 120 degrees detection angle or low-range directional narrow beam Besides the PIR occupancy detector switches with a full 360-degree detection zone you can have the surface-mounted plug an d socket CEDR + CESO (120 degrees directional detection angle) or the CEDR 6PLR + CESO (with a long-range directional narrow beam). Wall Mounted PIR Switches with 120 Degrees Detection Angle If you need a wall-mounted PIR switch with a plaster depth wall box (16mm), there's the WACE PIR and WAPIR needing or not needing neutral wire respectively. They both have a 120-degree detection angle. Where Do People Use PIR Switches? The PIR switches are becoming very common both at home and in the office, since they have a time lag switch incorporated which automatically turns ON or OFF the lights when activated, dealing once and for all with the problem of "I forgot the lights ON!" This means you can use PIR switches and time lag switches in places like the living room, the bedroom, in offices, factories, schools, workshops, factories, hotels, canteens, staff rooms, corridors, stairwells, changing rooms, students accommodations, toilet blocks, military accommodation, etc. And you can buy them at some of the most affordable prices via, Time Lag Switches, and, Occupancy Detector Switches, on our website.
