The light can be set to stay ON for any time between approximately 10 seconds(turn TIME knob fully anti-clockwise) and a maximum of 30 minutes(turn TIME knob fully clockwise). Any movement detected before this time elapses will reset the timer. You can adjust it according to locations and site requirements. It is recommended to select the shortest time to adjust the detection zone and perform the walk test.
The chosen light response threshold can be adjusted from approximately 3-2000LUX.Turn it fully anti-clockwise to select the dusk-to-dawn operation and turn it fully clockwise to select continuous daylight operation. You can adjust it according to locations and site requirements. The knob must be turned fully clockwise when adjusting the detection zone and performing the walk test in daylight.
IRIS S20 is a 360° ceiling-mounted PIR motion sensor engineered for long corridors and passages. With up to 20 m detection distance and a narrow, corridor-friendly coverage pattern, it turns lights ON the moment someone enters the zone and switches them OFF after the set delay. Adjustable daylight (3–2000 lux) and time (10 seconds to 30 minutes) settings let you fine-tune operation for safe, efficient lighting in indoor circulation areas
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 S20 PIR Motion Sensor automates lighting in long, high corridors and indoor passages with 360° ceiling coverage and up to 20 m reach.
Built specifically for corridor and passage applications, IRIS S20 creates a long, narrow detection field along the length of the hallway. It switches lighting ON as people walk through and keeps escape paths clearly visible, then turns lights OFF after the corridor becomes empty.
Perfect for office, school, hospital and institutional corridors that see frequent movement throughout the day. The 360° ceiling-mounted sensor responds quickly to people entering from any direction, ensuring safe circulation without burning lights 24/7
With an installation height of 4–10 m, IRIS S20 works reliably in tall walkways, internal atriums and gallery-type corridors. It maintains comfortable light levels during activity and allows luminaires to switch OFF automatically when the space is vacant.
Ideal for long service corridors, back passages and support areas that don’t need permanent lighting. IRIS S20 detects movement of staff along the route, bringing lights ON only when required and significantly reducing burning hours and maintenance costs.
Reliable emergency lighting for underground and multi-level parking facilities, ensuring safety in low-light conditions.
Experience intelligent, long-distance presence detection with IRIS S20’s 360° PIR sensor head, adjustable lux and time delay controls.
In Daylight mode, IRIS S20 only turns lights ON when the sensor detects motion and the ambient light level is below the selected threshold (adjustable from about 3 to 2000 lux). This prevents corridor lighting from switching on unnecessarily when there is enough natural or background light already present.
When the corridor or passage is already bright, the sensor keeps the load OFF even if people are moving, avoiding wasted energy.
As soon as the light level drops below the chosen lux setting and IRIS S20 detects movement, the lights switch ON automatically to maintain safe visibility.
Once traffic stops, the lights stay ON for the selected hold time (from around 10 seconds up to 30 minutes) and then switch OFF automatically
In No Daylight mode, IRIS S20 ignores ambient light and operates purely on presence detection. This is ideal for internal corridors, back passages or low-light routes where lights must always respond to occupancy, regardless of day or night.
When a person enters the 360° detection field beneath the ceiling-mounted sensor, IRIS S20 senses their infrared movement and switches the lights ON immediately.
As long as people continue moving within the corridor or passage, the sensor keeps the lighting ON, ensuring consistent illumination.
After the last detection and once the configured delay period expires, the lighting turns OFF automatically to save energy and prolong lamp life.
IRIS S20 includes an adjustable daylight sensor from about 3 to 2000 lux, so you can decide under what ambient light conditions the sensor should respond. This ensures artificial lighting is only used when corridor light levels are genuinely low
Optimised for up to 20 m corridor detection, IRIS S20 lets you adjust sensitivity so the sensor covers just the intended length and width of the passage. This helps avoid unwanted triggers from side rooms or distant movement outside the target path
Every time the PIR detects new movement, the internal timer resets. Lights remain ON for the entire duration of activity—whether people are walking continuously, moving equipment or making frequent trips along the corridor
IRIS S20 offers a wide hold-time range, from approximately 10 seconds up to 30 minutes. This allows you to configure shorter delays for low-traffic passages or longer durations for main circulation routes that need extended illumination after each use
Find answers to common questions about IRIS S20
Nano 16 is a compact microwave motion sensor by Sensinova that uses a high-frequency 5.8GHz signal to detect motion. It is designed for automatic lighting control and energy saving, turning lights ON when motion is detected and OFF after a set period.
IRIS S20 is specified for corridor / passage applications with a long, narrow detection pattern—up to around 20 m length at typical indoor temperatures when mounted at the recommended height. Actual coverage depends on installation height (about 4–10 m), environment and sensitivity setting, so on-site testing is recommended.
IRIS S20 operates from 220–240 V AC and is rated to switch common lighting loads such as incandescent and LED luminaires within its specified output (for example, up to around 2000 W incandescent and 1000 W LED in many versions). Always verify the exact rating and wiring diagram in the official data sheet and confirm compatibility with the luminaire manufacturer or your electrician
IRIS S20 is a ceiling-mounted PIR sensor designed for indoor use (typically IP20). It is installed on the ceiling of corridors or passages at heights between about 4 and 10 m, providing 360° coverage below. Follow the cut-out/fixture details, wiring instructions and safety guidelines in the installation manual to ensure reliable operation.
Yes. IRIS S20 offers adjustable parameters including detection sensitivity, hold time (approx. 10 seconds to 30 minutes) and daylight (lux) threshold (around 3–2000 lux). These settings let you fine-tune detector behaviour to match corridor length, mounting height and desired lighting strategy.
IRIS S20 is ideal for indoor circulation spaces that benefit from long-range, presence-based control: office and institutional corridors, apartment or hotel passages, gallery-type walkways, long service corridors and other narrow, elongated spaces where automatic lighting improves comfort and reduces running costs.
