441 Occupancy Detector Interface

Occupancy Detector Interface (441)

The 441 Occupancy Detector Interface allows connection of a customer-specified occupancy sensor to a DIGIDIM-DALI system. The input accepts a volt-free, normally closed contact. The prewired encapsulated circuit board is intended for mounting inside the wiring space of the sensor.

The 441 also includes a 12 V DC supply (15 mA max.) to power the sensor.
