Hard-wired occupancy sensor
The Acuity Sensor Switch RM PDT 9 is a hard-wired occupancy sensor that combines passive infrared and microphonic detection. It mounts on a ceiling and covers 2,463 sq ft at the suggested height. The unit operates on 12V DC or 24V DC power and has a white finish. It is suited for commercial lighting control projects that require dual-technology sensing.
Adaptive time delay under load
The sensor uses an adaptive time delay that adjusts automatically between 30 sec and 20 min based on occupancy patterns. Manual override is also available for fixed timing. This behaviour prevents lights from cycling during sustained activity while still releasing the circuit when the space empties. Dual-technology sensing reduces false triggers from air currents or minor vibration.
Coverage and voltage limits
The 2,463 sq ft coverage figure applies only at the suggested mounting height; lower or higher installation changes the detection footprint. The device accepts only 12V DC or 24V DC supply, so it cannot connect directly to mains voltage without a separate power supply. Hard-wired communication means no wireless pairing or network integration is supported.

Questions about this item
How much power does the RM PDT 9 draw when it runs 24/7 on a 12V DC or 24V DC supply?
It operates on 12V DC or 24V DC hard-wired power, so consumption stays low and steady during continuous ceiling-mounted use.
What wiring and voltage source must already be in place for this sensor to function?
A hard-wired 12V DC or 24V DC circuit at the ceiling mounting point is required before installation.
Will the 2463 sq ft PIR and microphonic coverage overlap cleanly with older ceiling-mounted sensors on the same circuit?
Its adaptive 30 sec to 20 min time delay and dual-technology sensing reduce false triggers alongside legacy devices sharing the same low-voltage wiring.
