Occupancy sensor factory sourcing for US commercial lighting buyers
Establish the product family and buying brief before hardware is selected: occupancy sensing conditions, room geometry and the load-control interface still need to be stated.
A sensor count without a room plan leaves detection coverage and obstructions unresolved. Identify the activities and areas that must be detected, then ask for a proposed configuration. Lighting Occupancy Sensors Sourcing is an independent sourcing partner, not a manufacturer or installer.
Separate occupancy sensor hardware from vacancy sensors, desk occupancy analytics and seat-presence products. State whether the unit is expected to switch a lighting load directly or only to report occupancy to another controller. Ask which rooms, aisles or workstations must be covered rather than ordering a generic piece count.
Record room geometry and obstructions, mounting position and detection requirements, input voltage, load type and any dimming interface such as 0-10V dimming. Write mounting height in ft (or m) and the coverage radius requested, then say whether the device is expected at 120 V AC, 277 V AC, a 120–277 V AC nameplate, or a low-voltage node plus pack. Keep sensor technology, power requirements and the load-control interface on separate lines so a PIR occupancy sensor is not treated as a complete switching system.
Ask each factory to name the model, included accessories, packing and delivery scope. Confirm whether an external control or power module belongs in the quote. Review inquiry options, then open the order brief or contact form when the known items are listed.
Public product-family pages can explain typical detection patterns, but they do not validate a proposed room layout. Mounting height, beam angle, beam coverage and furniture shadows remain buyer inputs. Luminous flux of the connected luminaires matters only as a load description for switching or dimming, not as a substitute for occupancy coverage. An IES photometric file for the luminaire family is lighting evidence; it is not occupancy-sensor coverage at the stated mounting height.
Occupancy sensor procurement here means lighting-control sensing: presence detection that will switch or dim luminaires. It is not a workstation occupancy study, not a seat-sensor bill of materials and not a vacancy-only wall switch unless that behavior is written into the brief. If the project also needs high bay occupancy sensor units or line voltage occupancy sensor devices, keep those as named configurations rather than mixing them into one unlabelled quantity.
State ceiling or wall mounting, mounting height, coverage radius requested, partitions, HVAC motion and glass that can confuse passive infrared. Ask for a detection diagram with those assumptions. If the sensor will sit above open warehouse aisles, the same brief belongs on the high bay occupancy sensor application page rather than being treated as an office ceiling default.
Our service organizes requirements, requests factory wholesale quotes and compares inclusions. The named factory supplies model evidence. The buyer or a qualified project team confirms control behavior, commissioning responsibility and final order. No listing, IP rating or IES photometric file attached to a luminaire family is treated as occupancy-sensor approval.
Read the occupancy sensor procurement checklist before sending a quantity-only request. Optional budget (currency and unit or whole-order basis) and high-end, mid-range, budget or undecided supplier preference can travel with the same inquiry; they are buying preferences, not verified factory ratings.
You can start with occupancy sensor type, room geometry, quantity and destination even if the detection diagram is still incomplete.
