The light can be set to stay ON for any period of time between approx. 10sec(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 about 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.
IRIS S8 is a wall/ceiling-mounted PIR motion sensor designed as a compact, energy-saving switch for indoor lighting. It detects human movement in a full 360° field up to 8 metres and turns lights ON the moment someone enters—then switches them OFF after the set delay. With adjustable lux and time settings, IRIS S8 is ideal for offices, hallways, lift lobbies, staircases and common areas where you want reliable automation and lower power bills.
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 S8 PIR Motion Sensor automates lighting in high-traffic circulation and common areas with 360° coverage and up to 8 m detection radius.
Give visitors a welcoming, well-lit lobby without running lights all day. IRIS S8 detects people approaching from any direction, brings lights ON instantly and turns them OFF automatically after the set delay once the lobby is empty
Perfect for multi-apartment corridors and common stairwells. The sensor turns lights ON when residents walk through and keeps escape paths visible, then switches them OFF once movement stops—reducing 24/7 burning while keeping the building safe
Ideal for basement or covered parking zones where natural light is limited. IRIS S8 activates luminaires when vehicles or pedestrians enter its 360° field and allows lighting to turn OFF after the configured hold time, cutting energy use in low-occupancy hours.
Use IRIS S8 in shopping malls, office corridors, storage rooms and other shared areas that see intermittent movement. The compact sensor helps ensure lights follow occupancy—ON when spaces are in use, OFF when they’re not.
Reliable emergency lighting for underground and multi-level parking facilities, ensuring safety in low-light conditions.
Experience reliable, presence-based lighting with IRIS S8’s 360° PIR sensing, adjustable lux threshold and flexible time delay
In Daylight mode, IRIS S8 only switches lights ON when two conditions are met: motion is detected and the ambient light level is below the selected lux threshold (adjustable from about <3 to 2000 lux). This prevents lights from coming ON unnecessarily in naturally bright lobbies, corridors or stair landings
When the area is already bright, the sensor keeps the lights OFF even if it detects movement, avoiding wasted power.
When the ambient light drops below the chosen lux level and IRIS S8 detects movement, it switches the connected lights ON automatically to maintain safe visibility.
Once motion stops, the lights remain ON for the selected hold time (from about 10 seconds up to 7 minutes) and then switch OFF automatically
In No Daylight mode, IRIS S8 ignores ambient light and works purely on PIR movement detection. This is ideal for enclosed or consistently dim areas such as internal corridors, basement passages or covered parking where lights must always respond to occupancy, regardless of day or nigh
As soon as a person enters the 360° detection field, the sensor responds to body heat and switches the lights ON.
As long as movement continues within its 8 m radius field (at typical mounting heights of 2.2–4 m), IRIS S8 keeps the lights ON for continuous comfort and safety.
After the last movement is detected and the configured delay expires, the lighting turns OFF automatically, reducing energy consumption and lamp wear.
IRIS S8 includes an adjustable daylight (lux) control from <3 to 2000 lux, letting you decide at what brightness the sensor should start responding. Lights only come ON when the corridor or lobby is genuinely dim.
Optimised for an 8 m (radius) detection distance and 360° coverage at 2.2–4 m mounting height, IRIS S8’s sensitivity can be tuned so it focuses on the intended area and avoids triggers from beyond the target zone.
The time delay is extended automatically when new movement is detected. Every additional presence restarts the timer, keeping lights ON continuously while people are using the space
Adjust the hold time from around 10 seconds to 7 minutes to match real usage—shorter for low-traffic corridors or staircases, longer for busy lobbies and common areas
Find answers to common questions about IRIS S8
IRIS S8 is a PIR (Passive Infrared) motion sensor and energy-saving switch designed for wall or ceiling mounting. It detects infrared energy from the human body within a 360° field and automatically switches connected lights ON when someone enters the detection area, then OFF after a preset dela
IRIS S8 offers a 360° detection range with up to 8 m radius at temperatures below about 24 °C, when mounted at heights between approximately 2.2 m and 4 m. Actual coverage can vary with installation height, layout and movement direction, so an on-site test is recommended
IRIS S8 is rated for typical AC lighting loads—for example up to about 400 W incandescent and 200 W LED (220–240 V AC versions; check your exact variant). Always verify the load rating and wiring diagram in the data sheet and confirm compatibility with the luminaire manufacturer or a qualified electrician
IRIS S8 is designed for easy installation on ceilings or walls. The bottom base is fixed at the selected point; wiring is connected as per the diagram; then the upper cover is locked back into place. During installation you should avoid pointing the sensor towards heat sources, moving curtains or reflective surfaces such as mirrors.
Yes. IRIS S8 provides adjustable settings for daylight (lux) level and time delay. The lux control lets you set operation from <3 up to 2000 lux, while the time control allows a delay between roughly 10 seconds and 7 minutes. These adjustments help you fine-tune how and when the lights operate
IRIS S8 is suitable for a wide range of residential and commercial locations, including lift lobbies, multi-apartment corridors, common staircases, basement or covered parking areas, shopping malls, office passages and other common areas where motion-based lighting improves safety and saves energy.
