Frequently asked questions

  • How much energy will the motion sensor save?

    Depends heavily on occupancy patterns. Active zones (continuous traffic): 10-20% additional savings. Mixed zones (workers come and go): 30-50% savings. Low-occupancy zones (storage, late-night warehouses, parking lots): 50-70% savings. The math: for a 150W fixture running 4,000 hours/year, a 50% occupancy-rate dimming saves about $80/year per fixture at $0.13/kWh.

  • Can I cover a 60 × 80 ft warehouse with one sensor?

    No. The 30-ft detection radius gives roughly 60-ft diameter coverage. For larger zones, use multiple sensors — one per 60-ft section, with sensors networked to control their respective zone of fixtures. For a 60×80 ft warehouse, plan for 2–3 sensors covering different zones.

  • Does it work with my existing GGJIA high bay?

    Yes, if the fixture is 0-10V dimmable (every GGJIA linear high bay). Verify by checking the spec sheet for "0-10V dimming" — if it says triac or ELV, the sensor is not compatible.

  • Will it false-trigger from HVAC or traffic outside the room?

    PIR sensors are designed to detect body heat changes within their field of view. They don't trigger from sounds, vibrations or motion outside the IR view. However, hot air currents from HVAC vents can cause false triggers — avoid mounting sensors within 6 ft of supply registers. Direct sunlight through windows can also occasionally trigger; orient the sensor away from windows.

  • Can I use this with a wired 0-10V dimmer too?

    Yes. A motion sensor and manual dimmer can work together — the sensor turns the fixture on/off based on occupancy, while the dimmer sets the desired brightness when on. Wire both in parallel on the same 0-10V circuit. The dimmer setting acts as the upper limit (e.g., dimmer at 60% = fixture ramps to 60% on motion, dims to standby when no motion).

  • Is there a wireless version?

    Yes. The wireless variant (separate SKU, contact sales@ggjia-led.com) uses a 433 MHz wireless signal to communicate with fixture-side receivers, eliminating the need to run 0-10V wiring between sensor and fixtures. Best for retrofit installations where running new wiring is expensive.

  • How do I set the hold time?

    Locate the small dial on the back of the sensor labeled "HOLD" or "TIME". Rotate to the desired hold time (30 seconds at minimum, 30 minutes at maximum). For active work zones, 5–10 minutes is typical. For storage and low-occupancy zones, 1–2 minutes maximizes savings.

  • Can I bypass the sensor and run the fixture at 100% always?

    Yes. Wire the fixture's 0-10V leads directly to a manual switch or 0-10V dimmer instead of the motion sensor. The fixture operates normally on/off via the manual switch, and the motion sensor can be added later if desired.

  • What's the warranty on the motion sensor?

    5 years full replacement, same as all GGJIA accessories. Failures under warranty are replaced with a new sensor shipped from Spokane, WA with prepaid return shipping inside the continental U.S.
