Our PIR presence detectors are designed to provide automatic lighting control via CAN or DALI network. They detect movement using a PIR sensor to turn the load on. When an area is no longer occupied the load will turn off after an adjustable time out period. The miniature size together with multiple installation options make these products ideal for mounting in trunking or attached to luminaires. An adjustable internal light tube sensor provides light level information to the lighting control system allowing lights to be kept off or at minimum level if sufficient daylight is present. It also allows maintained illuminance on dimmable systems. We offer five types of PIR all of which are neat and compact and an ideal choice for mounting in trunking, on luminaires, and, in especially in with out Micro PIR, where aesthetics are important.
Our new Ceiling Microwave Detector offers both automatic and optional manual control of lighting via an isolated voltage free contact output. These detectors are ideal for environments with varying ambient temperatures such as car parks and schools.
ecoLUX PRESENCE DETECTORS
1. The DALI addressable LC-DALIPIR features our Progressive Sensitivity function to eliminate false triggering. There is also an integral lux detector, enabling the sensor to control daylight linking. Daylight linking can be configured either to keep lights off when there is sufficient ambient light, or used as part of a closed loop to maintain a pre-set luminance level in a dimmable system. When using the lux detector, an extra DALI address is assigned to the unit. The LC-DALIPIR is connected via a screw terminal on the rear in a standard DALI two wire configuration powered from the data line, or, where the current drain would be too high for the bus to be sustained, PIRs can be powered from the DALI64 using a 4-wire connection. An integral IR sensor allows the unit to be commissioned and used via a remote control. This allows the basic commissioning functions as well as adjustment of the time-out delay.The LC-DALIPIR can also be specified with custom painted bezels to help the sensor blend into the surface on which is it mounted.
2. The DALI Micro PIR is neat and compact and the ideal choice for mounting discretely within a luminaire. Movement is detected using a PIR sensor, which updates the lighting control network using a DALI interface. When an area is no longer occupied, the device times out after a configurable period. This detector features our Progressive Sensitivity function to eliminate false triggering. There is also an integral lux detector, enabling the sensor to control daylight linking. which can be configured either to keep lights off when there is sufficient ambient light, or used as part of a closed loop to maintain a pre-set luminance level in a dimmable system.
3. The LC-CANPIR presence detector detects movement using a PIR sensor, which updates the light controller using a CAN bus interface. When an area is no longer occupied, the device times out after a configurable period. This detector also features our Progressive Sensitivity function to eliminate false triggering. Connection is made by RJ12 connectors on the back of the unit; there are two of these to allow easy onward connection. Device ID is set during commissioning using an IR tool, and there is a visual alert to show when a device has not been addressed. The walk-test mode, indicated by an LED, helps when configuring the detector.
4. This LC-MPIR/VF switches mains and can be flush mounted into suspended and plasterboard ceilings. Configurable for any room occupancy style, via time and lux level adjusters, a passive infra-red quad sensor detects movement of any warm body within the detection zone and a photocell monitors the ambient light level.
When movement is detected and the ambient light is less than the chosen level (10 to 1000 lux), this PIR switches on the load. The ambient light threshold can be set by the user between around 100 lux and infinity (when the photocell is inactive and the load is switched on regardless of light level). If no further movement is detected within a pre-selected time (adjustable from 10 seconds up to 40 minutes), the PIR switches the load off again.
The LC-MPIR/VF mounts into a 73/75mm diameter hole in a ceiling void (requiring a depth of at least 95mm) and is also suitable for switching loads other than lighting, such as fans.
5. The LC-PIRCC presence detector detects movement using a PIR sensor, which updates the light controller using a solid state galvanically isolated clean contact interface. When an area is no longer occupied, the device times out after a configurable period. This detector also features our Progressive Sensitivity function to eliminate false triggering and features a walk-test mode to help with configuring the detector, with movement indicated by a built-in blue LED. This starts when the unit is powered up, and expires 30 minutes after movement detection stops. Adjustment for sensitivity and timeout period is made during commissioning using two trimmers on the rear of the unit.
Our PIRs are available in CAN, DALI and Clean Contact versions. Unique programming options and progressive sensitivity helps eliminate false triggering.
