PIR4 is an electronic movement sensor for recessed installation. PIR4 detects movements, combined with temperature variations, and switches on the connected luminaires when the door is opened. To switch off the luminaires, close the door or move away from the sensor’s detection range.
Connection system Micro12 (12Vdc), Micro24 (24Vdc)
MARKS AND SYMBOLS
passive infrared sensor
The PIR 2.0 (passive infrared sensor) detects motion, combined with temperature variations of at least 4°C in a cone with an opening of about 80°. For correct operation, the photocell of the sensor must be installed in a position which does not affect its sensitivity. Horizontal sensitivity (up to about 400 cm) and vertical sensitivity (up to 220 cm) may be reduced if the photocell of the sensor is installed in a position (or at a height) which reduces the detection cone, e.g. near shelves or sides of a wardrobe. It is also not recommended to install the photocell in line with the central closing of the wardrobe doors in order to avoid turning on when undesired caused by detection of minimum motions.
