L-DALI-MS1 multi-sensor performs motion detection



The LOYTEC L-DALI multi-sensor performs motion detection and measures the lux level. It integrates perfectly into the L-DALI product line of light controllers. With the already built-in infrared receiver, lighting scenarios can be recalled via a remote control or lighting groups can be dimmed. In combination with the L-DALI controller, the desired automation status is achieved with a single push of a button. Building-wide, the connection to DALI and the gateway connection to the respective building network, e. g. BACnet, LonMark, etc. ensure a secure and fast communication with LOYTEC devices.

Motion detection is performed with the PIR sensor of the LDALI-MS1. The motion detection is divided into 92 zones and thus very sensitive. The sensor can be tilted to max. 40° allowing a perfect targeting of the detection area. The opening angel of 98.5° at a mounting height of 3 m covers more than 38 m². Objects can be detected at a distance of up to 12 m.
