INSTRUCTION MANUAL
MS371
360° True Presence Microwave Sensor
Indoor Installation
1. INTRODUCTION The MS371 incorporates advanced technology which allows the sensor to pick up the smallest of movements including typing on a keyboard or breathing. The MS371 is a True Presence Microwave Sensor, also known as an Occupancy Sensor, which allows one to automatically turn on lights or electrical devices within the sensors rated load. This true presence microwave sensor detects through obstacles like doors, glass panels and thin walls, with a 360° detection range and adjustable settings. Easily integrated into new or existing installations. Its IP20 rating is limited to flush mount indoor use and installation must be done by a qualified electrician.

3. FUNCTION a. Sensor Can identify between day and night (Lux Mode):
The consumer can adjust working state in different ambient light. It can work in the day time and at night when it is adjusted on the ” ” (sun) position (max). It can work in the ambient light less than 3 LUX when it is adjusted on the “3” position (min). As for the adjustment pattern, please refer to the testing pattern. b. Time-Delay is added continually: When the sensor detects movement while the light is already on, the countdown timer resets. This means the light will remain On for the full set duration from the moment of the latest detection. c. Adjustable Time Delay: The sensor can be set according to the consumer’s desire (10s, 30s, 90s, 6min, 12min)
4. CONTROL SETTING INFORMATION ! Turn the TIME knob anticlockwise to the minimum (10s). Turn the
LUX knob clockwise to the maximum (Sun). ! Switch on the power; the sensor will require 30 seconds to warm
up. Once the sensor detects movement, the lamp will turn On. If no other movement is detected within the time duration set, the light will turn Off within the 10 seconds ±3 sec. ! Turn the LUX knob anticlockwise to the minimum (3). If the ambient light is more than 3 Lux, the sensor is not able to function. If the ambient light is less than 3 Lux (dark), the sensor will operate.
Note: When testing in daylight, please turn Lux knob to position, otherwise the sensor will not work!

6. INSTALLATION & WIRING OPTIONS
! Unscrew and remove fixing bracket from base of the sensor. ! Insert the power cable into the slot provided. ! Connect the power cable into the terminal block as per the wiring diagram. ! Identify the ideal field of view and use fixing bracket mounting holes to ensure
correct alignment for motion sensor. ! Drill holes and screw the fixing bracket to the marked location. ! Reconnect the sensor to the fixing bracket and fasten the screws. ! Once installation is complete, swivel the head to point in the intended direction,
secure it, and turn on the power to test.
WARNING: Danger of Death Through Electrical Shock Y Must be installed by professional electrician. Y Disconnect power source. Y Cover or shied any adjacent live components. Y Ensure device cannot be switched on. Y Check power supply is disconnected.

7. PRESENCE & PIR SENSOR INFORMATION 1. When the detection distance is less than 3 meters, the sensor detects human
presence(breathing) and keeps the connected load switched on without interruption, ensuring continuous illumination as long as presence is detected. 2. At a detection distance of 3 to 4.5 meters, the sensor operates as a conventional microwave motion sensor, this means it will detect motion and this will control the connected load.
Note: Microwave True Presence Sensors, also known as Occupancy Sensors, send out invisible waves and listen for tiny changes in the `echo’. They can pick up even smaller movements or detect movements through non-metallic obstructions. These occupancy sensing methods help ensure that the lights or other electrical equipment systems only run when needed, saving energy without omitting you in the room.
