Sensors

Specifying motion sensors for a project means checking load rating, detection method, IP rating and compatible fittings side by side, since these determine whether a sensor will switch the connected load safely, trigger reliably and suit its environment. A pir motion sensor detects movement through infrared changes in a space, making it the standard choice for corridors, storerooms and entries where straightforward occupancy detection is enough. Load rating needs to match the total wattage of the fittings it switches, since an undersized sensor will struggle with a bank of LED batten lights or panels on the same circuit. IP rating should suit the location: indoor, sheltered areas need less protection than covered outdoor spaces such as carports and loading docks. Confirming compatible drivers and dimming protocol, whether that’s leading-edge, trailing-edge, DALI or 0-10V, avoids flicker and callbacks once the sensor and fitting are both on site. For areas lit by battens, the Battens range covers fittings commonly paired with motion sensors in back-of-house spaces.

A complete commercial lighting spec rarely stops at motion sensors alone, since the sensor needs to be matched to a compatible fitting and control system before an order goes to site. Where a project calls for centralised, addressable control instead of a standalone motion detector, the DALI range gives specifiers a compatible protocol for zoning and scheduling across a whole floor or building. For open-plan offices, retail floors and other spaces needing uniform, glare-free illumination alongside motion-triggered switching, the Panels range pairs well with the sensor range. Specifying sensors, panels and control protocol from one supplier keeps compatibility questions to a single point of contact rather than chasing parts separately. Trade pricing and stock availability across the full range are confirmed through the Domus Partner network, so quantities and lead times are settled before work begins.
