LDALI-MS2 Multi-Sensor

DALI-2

The LOYTEC LDALI-MS2 multi-sensor performs occupancy detection and measures the lux level. It integrates perfectly into the L‑DALI product line of lighting controllers and LROC‑40x room automation controllers. The sensor uses a passive infrared presence detector, which is optimized for use in typical office environments, where even the small movements of somebody working at a desk have to be detected across the complete detection area. Its presence detection zone diameter of 10.8 m at 3 m mounting height is ideal to cover a typical office room or an area in an open office space. The LDALI-MS2 is suitable as highbay-sensor for mounting heights up to 12 m. The detection area for mounting heights from 5 m to 12 m is 256 m2.

With the built-in infrared receiver, the room’s lights, sunblinds and HVAC system can be controlled via the optionally available IR remote control L-RC1. In addition to occupancy and lux sensors, the LDALI-MS2 comes with integrated temperature and humidity sensors. In room automation applications, those values can be used to calculate the current dew point. On the back of the sensor, there is a connector for three digital inputs, allowing to connect conventional switches and push-buttons, window contacts, dew point sensor, etc. This feature not only saves on additional hardware, but also significantly reduces wiring costs, as the inputs can be wired inside the room and wires no longer have to be pulled to the I/O modules in the switching cabinet.

The LDALI-MS2 comes with three mounting options: It can be mounted in-wall in standard flush‑mounted boxes, spring snap in false ceilings and on-wall with the included surface mounting box.

Communication and power supply is handled via the DALI bus. The LDALI-MS2 is a DALI-2 certified input device as defined in the IEC 62386 2014 standard and can be integrated into DALI-2 systems of other vendors.
