The NOIR DUO 2-Channel Presence Sensor offers smart, independent control of two separate loads with dual-tech detection — combining true infrared presence sensing (up to 3m) with standard motion detection (3–8m) across a 360° range. Ideal for offices, hotel rooms, and retail spaces, it activates lights or AC only when needed, thanks to independently adjustable TIME1, TIME2, sensitivity, and LUX settings for each channel.
Distinguishing between day and night, and between stillness and movement, it’s perfect for spaces needing layered automation — like lighting on one channel and AC or fans on another. Professionally installed, the NOIR DUO enhances comfort, energy savings, and automation flexibility, making it a reliable choice for dual-load presence control.

Adjust the sensor's detection range from 2m to 16m by turning the reach knob. Turn it fully left for minimum range and fully right for maximum. Set based on location needs.
Choose how long the light stays ON (10 seconds to 12 minutes). Movement restarts the timer. Use the shortest time during setup and walk test for accurate adjustment.
Set light sensitivity from 2 to 2000 lux. Fully left = night-only mode (2 lux), fully right = day mode. Turn fully right during testing in daylight, then adjust per requirement.
1. Set LUX to SUN for test mode, then energise the circuit.
2. Walk in and confirm PIR first activation switches both channels ON.
3. Sit within the inner <3 m zone and confirm 24 GHz presence hold.
4. Leave and verify TIME1/TIME2 switch OFF independently after vacancy.
5. Reduce SENS if glass, curtains, fans or vibration causes unwanted ON.

NOIR DUO is a 2-channel presence sensor that combines true infrared presence sensing with standard motion detection across a 360° range. It controls two loads independently- lights and AC/fan, each with its own delay timer, keeping spaces comfortably lit and climate-controlled only when occupied, while saving energy when they're not.
Discover the simple yet effective way NANO 16 transforms your space
Emits 5.8GHz microwaves with <0.2mW power, ensuring precise detection.
Detects movement (0.6–1.5m/s) within 360° range, adjustable 2–16m.
Activates lights (≤800W incandescent / 300W LED) with 10s–12min delay.
A microwave motion sensor works by emitting high-frequency waves and detecting changes in the reflected signal. When motion occurs within the microwave sensor range, the reflection shifts, triggering a response. Unlike passive sensors, microwave sensors actively scan their surroundings, making them ideal for detecting subtle movement, even through walls or glass.

Use Noir Duo where one sensor must handle walk-in activation, seated presence hold, and two separately timed outputs. Keep direct load control within the rated channel limits; use a relay or contactor for heavier AC/fan loads or high-inrush equipment
Ceiling presence detection keeps lights on while seated and reading, even without movement.
Presence triggers both general floor lighting (L1) and focused display or shelf lighting (L2) independently — ensuring product visibility only when customers are present.
Guest enters: main lights (L1) and AC (L2) activate instantly at different delay settings. Guest leaves: times out independently for full automation.
L1 activates panel lights on entry. L2 triggers a AC — each with independent timers for layered, energy-smart automation.
Reliable emergency lighting for underground and multi-level parking facilities, ensuring safety in low-light conditions.

The hold time is set to 30 seconds, and the Lux level is set to 300. The light turns on when movement is detected and turns off after people leave, specifically at night. Applications include corridors and staircases.
With sufficient daylight (>300 Lux), the light remains off even when motion is detected.
With insufficient daylight (<300 Lux), the light turns on when motion is detected.
After the last detection and the elapse of the current hold time (30 seconds), the light turns off.
The daylight threshold is set to 2000 lux to disable the light. It turns on when movement is detected, and after people leave, the light turns off once the hold time of 30 seconds has elapsed. Applications include dimly lit areas such as basement parking and underpasses.
When motion is detected, the sensor will switch the light on to 100% brightness.
After people leave the detection area, the light remains at 100% brightness for the duration of the hold time.
After the last detection and the elapse of the current hold time (30 seconds), the light turns off.
Automatically adjusts between day and night modes based on ambient light levels, ensuring optimal performance in any lighting condition.
Fine-tune sensitivity from 2m to 16m to perfectly match your space requirements and prevent false triggers.
Smart motion detection resets the timer with new movement, ensuring lights stay on while the area is in use.
Customize the delay from 10 seconds to 12 minutes after the last detected motion to suit your specific needs.
Find answers to common questions about Nano 16
NOIR DUO controls two loads independently. Channel 1 (Lamp) and Channel 2 (AC/Fan), each with its own delay timer. Both channels activate together on presence, but they can time out separately. For example, lights might switch off after 15 minutes while the AC stays on for 60 minutes.
It uses dual-tech detection: true infrared presence sensing picks up micro chest movements from breathing within 3m, keeping lights on even when you’re sitting still, while standard motion detection covers 3–8m for broader movement across the room.
Mount it centrally on the ceiling at a height of 2.2–4m (3m is optimal), with a clear, unobstructed 360° view. Avoid mirrors, glass, or reflective surfaces, heat sources like AC vents or heaters, and moving objects such as curtains, fans, or plants, as these can trigger false detection.
Yes. The SENS knob adjusts detection diameter — turn toward (+) for large rooms up to 8m, or toward (–) for smaller spaces around 2m. The LUX knob sets the ambient light threshold — SUN for 24/7 operation, or position 3 for night-only activation below 3 LUX.
Channel 1 supports up to 7A (dry contact, NO) or 300W for LED loads. Channel 2 supports up to 10A (dry contact, NO/NC) or 300W for LED loads, and also includes an Impulse mode (load ON for 1s, OFF for 9s in a repeating cycle) for staircase or corridor lighting applications.
If a load won’t auto shut off, confirm there’s no continuous signal in the detection field, check that TIME isn’t set to maximum, and verify the load doesn’t exceed rated wattage. If a load isn’t triggering at all, check the power and wiring, confirm LUX matches ambient conditions, and verify the SENS range covers your detection zone.
