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 pre-wired encapsulated circuit board is intended for
mounting inside the wiring space of the sensor.
Key Features
• Includes a 12 Volt DC supply (15 mA max) to power the
sensor
• Fits into the wiring space behind the sensor
• Input for normally closed (NC) switch supports alarm
conditions
• Fully programmable using DIGIDIM Toolbox and Designer
software.
