High bay occupancy sensor application checks - Factory sourcing support for occupancy sensor

Application purchasing matrix

Application condition	Information to collect	Supplier confirmation
High-bay mounting	Mounting height, aisle width, rack shadows and whether the sensor sits on the luminaire or on the structure	Coverage diagram for the stated height, not a low-ceiling office lens
Electrical interface	Input voltage, switched load versus dimming interface, 0-10V dimming if used, wet location or IP rating only if the environment requires it	Load rating and included modules for that revision
Control behavior	Occupancy versus vacancy logic, time delay, daylight inhibit if specified, who commissions settings	Factory description of adjustable parameters, not a promise of energy-code sign-off

Which project conditions matter when specifying high bay occupancy sensor include mounting height, beam or aisle geometry, forklift motion and the connected lighting load. Site constraints change room geometry and obstructions, control behavior and commissioning responsibility. A warehouse lens that works at one mounting height can miss occupancy at another. Luminous flux of the high-bay luminaires describes the lighting system; it does not prove the sensor sees the floor. Compare required light output and distribution before treating fixture wattage as the occupancy-sensor decision. A 120–277 V AC input range that appears on some referenced lighting products is only a candidate to reconfirm on the sensor nameplate; it is not a universal occupancy-sensor specification.

Decisions that require the buyer or a qualified project team, rather than this sourcing service, include lighting calculations, energy-code interpretations, installation methods and final commissioning. We do not offer US field installation. Correlated color temperature and color rendering index belong to the luminaire RFQ, not to occupancy hardware, and should not be copied onto the sensor line as if they were sensing specifications.

Site conditions and purchasing impact

Open warehouse aisles

Site input: Aisle length, rack height, mounting height in ft (for example 20 ft versus 40 ft) and whether HVAC throw crosses the detection field.
Selection question: Ask whether the quoted high bay occupancy sensor coverage is drawn at the stated mounting height, and whether masks or lens options are included.

Manufacturing bays with obstructions

Site input: Cranes, mezzanines, partitions and heat sources that can affect passive infrared or other sensing methods.
Selection question: Record whether a ceiling mounted occupancy sensor office default was substituted, and keep that substitution labelled until the buyer accepts it.

If the same purchase also contains office ceiling units, do not merge them into the high bay occupancy sensor quantity. A typical check example: the brief states a high bay occupancy sensor count but omits mounting height, so two factory coverage diagrams cannot be compared. Record height and aisle width first, request diagrams at that height, and keep an office ceiling mounted occupancy sensor substitute labelled until the buyer accepts it. Continue with inquiry options, supplier matching, the order brief or the inquiry form. The checklist lists fields that should stay attached to each configuration.
