The LOYTEC LOYBT multi-sensors are Bluetooth SIG qualified multi-sensors for mesh ecosystems. They perform occupancy detection and measures the illuminance level. They integrate perfectly into the LOYBT product line and LOYTEC Bluetooth Mesh enabled controllers. The occupancy sensor uses a passive infrared presence detector and 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 have to be detected across the complete detection area.
The LOYBT-MS2/MS2-B/MS3/MS3-B provide a presence detection zone diameter of 10.8 m at 3 m mounting height and is ideal to cover a typical office room or an area in an open office space. As well it is suitable for highbay‑applications for mounting heights up to 12 m. The detection area for mounting heights from 5 m to 12 m is 256 m2.
The LOYBT-MS4 provides a flat lens and the presence detection zone diameter 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 LOYBT multi-sensors come 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.
Additionally the device acts as Bluetooth Mesh to DALI gateway. The integration of DALI ballasts into Bluetooth Mesh networks allows the use of proven luminaires, technologies and existing installations to be retrofitted easily. Up to 16 DALI-ballasts can be integrated with the help of the gateway. They can be separated in up to 4 groups, which are exposed to the Bluetooth Mesh ecosystem as individually accessible Bluetooth Mesh luminaires.
The sensor is powered either via a DC power supply (12V-24V) or a DALI power supply (e.g. LDALI-PWR1-U). If a DALI power supply is used, additional DALI ballasts
can be connected to the DALI-line and controlled via the gateway function of the sensor.
The LOYBT-MS2/MS2-B 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 mounting kit LOYMS2-OW/LOYMS2-OW-B (must be ordered separately). The LOYBT-MS3/MS3-B/MS4 are designed to be used with spring snaps in false ceilings.
