Wiring diagram
Sensor engineering wiring reference — RS485/dry contact to RCU or modules; terminals per signed drawing set.
Installation notes
- Keep lens unobstructed; stay clear of HVAC outlets and heat sources
- Presence sensors require confirmed mounting height and coverage
- Wire per project drawing; signed projects use factory shipment drawings
- After power-on commissioning: trigger distance, linkage logic and energy strategy acceptance
