The LOYTEC L-DALI multi‑sensors perform occupancy detection and measures the illuminance level. It integrates perfectly into the L‑DALI product line of light‑ ing controllers and L-ROC room automation controllers with DALI interface. The occupancy sensor uses a passive infrared presence detector and a an acoustic presence detector. The sensor is optimized for use in typical office environments where even the small movements of somebody working at a desk and hitting the keyboard have to be detected across the complete detection area.
The LDALI-MS2-BT/MS2-BT-B/MS3-BT/MS3-BT-B provides a presence det zone diameter of 10.8 m at 3 m mounting height and is ideal to cover a typi‑ cal office room or an area in an open office space. As well it is suitable for high‑ bay‑applications for mounting heights up to 12 m. The detection area for mount‑ ing heights from 5 m to 12 m is 256 m2.
The LDALI-MS4-BT provides a flat lens and the presence detection zone diamete is 7 m at 3 m mounting height.
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 illuminance sensors, the multisensor comes with integrated temperature and humidity sensors. In room automation applications, those val‑ ues 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.
Furthermore, they can transmit all supported beacon-types (iBeacon, Eddystone UID beacon or manufacturer specific LOYTEC beacon) for indoor localization.
The LDALI-MS2-BT/MS2-BT-B comes with three mounting options: It can mounted in‑wall in standard flush‑mounted boxes, spring snap in false ceilings and on‑wall with the the mounting kit LOYMS2-OW (must be ordered separately). The LDALI-MS3-BT/MS3-BT-B/MS4-BT is designed to be used with spring snaps in false ceilings.
Communication and power supply is handled via the DALI bus.
The L-DALI multi-sensors are DALI-2 certified according to the IEC 62386 standard and can be integrated into DALI‑2 systems of other vendors.
