IR W2180 PIR wall mount motion sensor:
IR W2180 is a wall mount infrared motion sensor. The assembly of highly sensitive pyro-sensor and specially designed reflector provides the unmatched coverage of 180° with an angle of aperture of 90° and maximum reach of 12 meters.
Motion sensor:
Motion sensor is an intelligent device which controls the ON-OFF operation of electrical loads. When it detects motion inside its detection area, it automatically turns the load ON. It turns OFF the load after preset time delay if no movement is detected for the set time.
It provides artificial light only when it is needed. This reduces the large amount of energy wastage and helps in making the most energy efficient lightings.
IR W2180 – wall mount PIR motion sensor:
IR W1120 is a wall mount passive infrared motion sensor. The assembly of highly sensitive pyro-sensor and specially designed reflector provides the unmatched coverage of 180°. It detects heat radiated from a body. Segmented lenses divide the whole detection area into passive and active zones. When any warm object like human body moves between the zones, it is detected as a change in voltage by the pyro-sensor. When it detects such movement, it triggers the switching mechanism to operate the connected load.
As the pyro-sensor operates by detecting change in the temperature, the ambient temperature plays important role in working of this motion sensor. Maximum detection reach distance mentioned in the technical specifications is measured at the ambient temperature of 25⁰ C. Detection reach distance might change with the change in ambient temperature.
Selecting the installation location:
Mounting height: With the increased mounting height, the detection area increases and sensitivity to detect the movement is reduced. Hence the product must be installed at the optimal mounting height to suit the particular application.
● Detection cone: Make sure to cover the required detection area. Avoid window surfaces.
● Avoid exposure to direct light. This may disturb the operation of photocell and it might not able to measure the correct ambient brightness level.
● Do not place devices that radiate heat inside the motion sensor’s detection zone.
● Minimum distance of 50 cm should be maintained between the light and the motion sensor, since the heat radiated from the light source could result in false triggering of the sensor.
● Avoid disturbance or distraction by obstacles or moving objects like fan, curtains, ventilator drafts, hanging lamps, trees, etc. It cannot detect the movement through obstacles like glass partition, wall, etc.
● Passive infrared motion sensor detects movements at right angles (tangential movement) more precisely. Decide the place for installation accordingly.
Adjustable settings:
Three settings are available to adjust the operation of the motion sensor to suit the particular application. These setting can be altered any time. The last setting will remain stored in the system in the event of power failure.
Reach setting:
Motion sensor’s detection reach distance can be set with the help of Reach setting knob.
Set the knob fully anticlockwise to set the minimum reach distance of 2 m. To set the maximum reach distance of 12 m, set the knob fully clockwise. Similarly intermediate settings can be done by adjusting the knob accordingly.
Twilight setting:
With in-built photocell, motion sensor continuously measures ambient light and constantly compares it with the preset lux level. Load is switched ON when ambient light falls below a specific threshold while it detects the movement. When there is enough ambient light (above the set threshold value), motion sensor does not turn ON the load even there is any movement inside the detection area.
This threshold value of lux level can be set with the help of twilight setting knob. Set the knob fully anticlockwise to set the minimum lux level of 10 lux. This will turn ON the load by movements only when the ambient brightness is very low, hence during the night time. To set the maximum lux level of 2000 lux, set the knob fully clockwise. This will turn ON the load by movements even in the full ambient brightness condition, i.e. even during day time. Similarly intermediate settings can be done by adjusting the knob accordingly.
There is no clock inside the system. Hence motion sensor decides the time based on the ambient light level.
Time setting:
When motion sensor detects any movement inside its detection area, it automatically turns the load ON. It turns OFF the load after preset time delay if no movement is detected for the set time.
This off-delay time can be set with the time setting knob. Set the knob fully anticlockwise to set the minimum time of appox. 10 sec. To set the maximum time of 8 min, set the knob fully clockwise. Similarly intermediate settings can be done by adjusting the knob accordingly. Any movement detected during this off-delay time will re-start the timer.
Installation:
When power is applied to motion sensor, it calibrates its system. During this calibration process, load turns ON for the preset off-delay timing. It takes around 20 seconds of time till it comes to steady state condition. During this time motion sensor does not detect any movement. Modify any setting only after it comes to steady state condition.
Follow the below sequence for required time, lux and reach distance settings.
- Set the Time to minimum, Lux to maximum (Day mode) and Reach distance to maximum.
- First, set the desired value of Reach distance by performing walk test.
- Adjust the Time setting knob to set the required off-delay timing.
- Set the desired lux value by adjusting the lux setting knob.
