This Multi-Sensor is a high bay ceiling mounted passive infrared (PIR) sensor designed to be part of the WaveLinx Wired local bus. MTSHB includes a high sensitivity PIR sensor suitable for high ceiling or high bay applications up to 40 feet, such as warehouses and factories, and where high detection sensitivity is needed. Functioning as a presence sensor, the unit returns occupancy data to the WaveLinx Wired network. The integrated photocell provides a light level measurement value to the WaveLinx Wired network for daylight dimming applications.
