HF A1360 is a high frequency ceiling and wall mount motion sensor. It provides precise light threshold, time and reach setting with the help of micro switches. This not only makes it precise but also very easy for user to modify the setting if the requirement changes in future. 


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.


HF A1360 – HF Ceiling and Wall mount Motion sensor

HF HB1360 is a High Frequency ceiling and wall mount motion sensor. It has cutting-edge HF-sensor operating as the heart of its system. It is a trans-receiver of high frequency microwave signals. First it emits the signals which are reflected back from the surrounding objects, like wall, furniture or floor. It receives the echo of the reflected signals. Whenever there is any change in the received echo that means the movement is detected inside the detection area and the sensor triggers the switching mechanism. This detection technique is irrespective of ambient temperature and hence it gives the seamless performance over the various climate conditions.

Because of its HF-sensor technology, it can detect motion through doors, glass partitions, thin walls, wooden or stud walls, etc. Hence it can be installed under the false ceiling or inside furniture paneling, giving no hint of its presence from outside.

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.

Avoid disturbance or distraction by obstacles or moving objects like fan, curtains, ventilator drafts, hanging lamps, trees, etc.

Near the edge of its detection area, it provides better detection to the tangential movements.


Motion sensor connection terminals


 Motion sensor has 4 connection terminals.

L’: Phase OUT to load

N’: Neural for load

L: Phase IN

N: Neutral IN


Indicator LED


 There is an indicator LED fitted on the motion sensor. This indicates the working condition of the motion sensor.

During the power up: Motion sensor calibrates its system when power is applied by turning ON the switch. During this calibration process, the indicator LED flashes couple of times. This indicates the proper phase and neutral connections are in place. Once the calibration process finishes, the indicator LED becomes steadily OFF.

During the normal operation: Indicator LED turns ON when motion sensor detects any movement inside the detection area and remains ON for the set off-delay time.


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.

Time, Reach and Twilight values can be precisely set with the help of micro switches. These eight micro switches are divided in 3 groups to set the Time, Reach and Twilight values as below.

Switch 1 and 2: Reach distance setting

Switch 3,4 and 5: Time setting

Switch 6,7 and 8: light threshold setting




When power is applied to motion sensor, it calibrates its system. During this calibration process, indicator LED flashes couple of times and also load is turned ON for few seconds. It takes around 10 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, light and reach distance settings.

-          Set the Light maximum (Day mode) and Reach distance to maximum.

-          First, set the desired value of Reach distance by performing walk test.

-          Adjust the Time setting to set the required off-delay timing.

-          Set the desired light value by adjusting the l setting switches.
