The light can be set to stay ON for any period of time between approx. IOsec(turn fully anticlockwise) and a maximum of 12min(turn fully clockwise). Any movement detected before this time elapse will re-start the timer. It is recommended to select the shortest time for adjusting the detection zone and for performing the walk test.
The chosen light response threshold can be adjusted from <3-2000 Lux. Turn it fully anti-clockwise to select dusk-to-dawn operation at aboutl., 2 Lux. Turn it fully clockwise to select continuous daylight operation. The knob must be turned fully clockwise when adjusting the detection zone and performing the walk test in daylight, then adjust setting according to site requirement.
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.

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.

Discover how the IRIS S12 PIR Presence Sensor brings intelligent, surface-mounted lighting control to work and circulation areas.
Enable hands-free lighting in cabins, small offices and shared work areas. IRIS S12 senses movement in its PIR field and turns lights ON as soon as someone enters, then switches them OFF after the room has been vacant for the set delay.
Improve hygiene and convenience in common and premium washrooms. IRIS S12 automatically activates the lights when a user enters and turns them OFF after they leave—so switches don’t get touched repeatedly and lights are never left running all day.
Keep corridors, lift lobbies and internal passages safely lit only while they’re in use. The surface-mounted IRIS S12 monitors movement along the path and ensures the lights follow occupancy instead of burning 24/7.
Avoid dark stairs without permanent ON lighting. IRIS S12 reacts quickly to people using staircases and landings, providing automatic ON during movement and OFF after the configured hold time, improving safety and reducing power bills.
Reliable emergency lighting for underground and multi-level parking facilities, ensuring safety in low-light conditions.
Experience responsive, presence-based lighting with IRIS S12’s PIR sensing and adjustable time and daylight settings.
In Daylight mode, IRIS S12 only turns lights ON when both conditions are met: motion is detected and the ambient light level is below the chosen lux threshold. This prevents lights from switching on in naturally bright spaces such as window-side offices, bright corridors or washrooms with daylight.
When the space is already bright enough, the sensor keeps the light OFF even if motion is detected, avoiding wasted energy.
When the room becomes dim and IRIS S12 detects movement, it switches the lights ON automatically for safe and comfortable visibility.
Once motion stops, the light remains ON for the selected hold time and then turns OFF automatically, ready for the next occupancy event.
In No Daylight mode, IRIS S12 ignores ambient light and works purely on presence detection. This is ideal for enclosed or consistently dim zones—like internal washrooms, back corridors and internal cabins—where lights should always respond whenever movement is detected.
As soon as a person enters the detection area, the PIR sensor responds to body heat and brings the lights ON to full brightness.
As long as movement continues within the field of view, IRIS S12 keeps the lights ON, ensuring a safe and comfortable environment.
After the last detected movement and once the configured hold time expires, the lights switch OFF automatically to save energy
IRIS S12 includes an adjustable daylight (lux) threshold so you can decide at what brightness level the sensor should start responding. This ensures artificial lighting is only used when natural light is no longer sufficient
Fine-tune the detection area to match each space. IRIS S12 offers sensitivity adjustment so it can focus on the intended zone and reduce false triggers from neighbouring corridors, open doors or nearby movement.
Every new movement detected by IRIS S12 resets the internal timer. Lights remain ON continuously while people are moving or working within the detection zone, preventing sudden switch-offs in busy offices or washrooms.
Choose how long the lights stay ON after the last motion—from short delays for washrooms and corridors to longer timings for cabins and lobbies. This lets you adapt sensor behaviour to the way each area is actually used.
Find answers to common questions about IRIS S12
IRIS S12 is a surface-mounted PIR (Passive Infrared) presence sensor designed for automatic lighting control in indoor spaces. It detects human movement within its field of view, turns lights ON when someone enters the area and switches them OFF after a preset delay, improving both safety and energy efficiency.
IRIS S12 is designed for typical indoor mounting heights and provides a wide detection area suitable for small to medium-sized rooms, corridors and washrooms. The effective range depends on mounting height, sensor orientation and the selected sensitivity level. For precise figures, refer to the IRIS S12 technical data sheet.
IRIS S12 can be used with most commonly installed lighting fixtures when wired according to the connection diagram—such as LED luminaires with appropriate drivers and other loads within the sensor’s rated output. Always confirm compatibility and load ratings with the luminaire manufacturer or a qualified electrician.
IRIS S12 is a surface-mount sensor, fixed directly onto ceilings or suitable wall/soffit surfaces. Once installed at the recommended height and angle, it provides PIR coverage over the target area. The mounting procedure, wiring and cut-out/clearance requirements are detailed in the installation instructions provided with the sensor.
Yes. IRIS S12 offers adjustable parameters such as detection sensitivity, hold time (delay) and daylight (lux) threshold. These allow you to tune how quickly lights switch OFF and under what light conditions they should turn ON, depending on the space and application.
IRIS S12 is suited for indoor spaces that benefit from presence-based lighting control, including offices and cabins, washrooms and toilets, corridors and lift lobbies, staircases, landings, study rooms and similar areas in both commercial and residential projects
