Occupancy Sensors error codes, explained

Lutron, Leviton and similar auto-off sensors. Codes below: Adjustment guides. Each guide covers what the code means, what you can safely try yourself, when to stop and call a technician, and what the repair typically costs.

Lights keep turning off while people are working

The office classic: someone typing quietly gets plunged into darkness and waves their arms at the ceiling. Documented cause: PIR (passive infrared) sensors need line of sight and meaningful motion — still, seated work reads as an empty room, so the timeout fires. Documented fixes, in order of effort: lengthen the timeout, raise sensitivity, or upgrade to dual-technology sensors (PIR + ultrasonic — the ultrasonic side detects micro-motions like typing, no line of sight needed), which the trade literature specifically recommends for offices and conference rooms.
