The UltraLink receiver/controller (ULTRA) installs inside fixtures that don’t have a sensor onboard.
Sensors and switches send commands wirelessly via Bluetooth NLC to UltraLink receivers/controllers, telling the fixture how to operate based on motion, daylight, switching, or scheduled events (ULTRAGATEWAY accessory required for time-based events).
Typically, about 75% of fixtures will have a receiver and 25% will have sensors.
Range is highly dependent on the integration of fixtures, environment, and conditions. It is recommended to conduct testing for range accuracy.
