Interior light with built-in motion sensor. The interior light detects motion through a PIR-sensor, lights up and stays active for 3 minutes and then deactivates itself. Choose between surface or recessed mount. The recessed lamp is only 3,2 mm thick! Depth is 23 mm and hole diameter ø 160 mm. The interior light has a white plastic rim that is fastened with four screws. To synchronize, install one master lamp with motion detector and attach it to one or several slave lamps without motion detector. Five slave lamps can be installed with one PIR master light and the maximum distance apart should not exceed 7 meters. The lights have a 18 cm outgoing cable harness with three cables: plus, minus/ground and one synchronization cable. If an interior light (slave) is to be used as a stand alone, connect the yellow synchronization cable to the black plus cable, and attach the white cable to minus/ground. The yellow cable does not need to be installed if an interior light (master) is to be used without synchronization. The stand alone variants should be selected if you do not want the PIR functionality.
