1. Features
This is a RS485 protocol sensor of independently flush mounting(compatible with 86 type box). The sensor,
controlling and exchanging data through RS485 protocol, has functions of big motion, minor motion, breathing
detecting+light sensing and so on. Adopting 5.8GHz RS, high gain low impedance technology, MSA043D is
achieving presence detecting as its big advantage. Besides, MSA043D can independently access RS485 system
as a unit of data collecting for its RS485 communication standard.

3. Function
Adopting fixed 30S cyclically reporting mechanism, the product, transmits human condition information(no
human-existing/human-existing:big motion mode, minor motion mode, breathing mode) and illumination data
through RS485 communication protocol.
Big motion actives Minor motion& Breathing signal maintains
Big Motion Mode: Detecting the signals of human greatly moving (walking) in detecting area within 30S.
Minor Motion Mode: Detecting the signals of only human slightly acting in detecting area within 30S, such as:
leaning forward, leaning back, body swing, shaking head, typing, using cellphone and other slighting acting.
Breathing Mode: only human breathing signal is detected(the expansion of abdomen and chest without
big motion and minor motion within 30S in detecting area).
Ambient Light Level Report: Reporting light level when the change value of ambient light is more than
preset difference value.

Note
1. The default compensation factor is 1 times. For different installation environments, set the corresponding
compensation factor after verifying and calibrating with the illuminance meter.
2. Return 000005FF01XX, If there is no above features or command is issued incorrectly.
3. Return 000005FF02XX, If setting data range is incorrect.

Note: Long press the switch for 3S to reset, and the product enters the initialization state.
8. Detecting Area
Note:
1. Considered the features of electromagnetic wave transmitting, the effective range of radar will vary to some
extent as the radar is related to size of transmitter and material and thickness of the target cover.
2. Electromagnetic waves in centimeter wave frequency band can penetrate non-metallic materials, such as
glass, wooden board, screen and thin wall and can detect the moving objects behind cover but can not
penetrate thick wall, metal door and so on.

9. Installation Instruction
1) Flush mounting
2) Flusn mounting in 86 box
1. Ceiling mounting with a cut of 55-65mm
2. Connect wire on the terminal
3. The middle circle is the reset button
4. Bending the spring clip backward to
push it into the pre-opened hole in the
ceiling
5. Make sure it’s stable and reliable after
installation
1. Connect wire on the terminal
2. Fasten the product to the junction box( light window upward)
3. Make sure it's stable and reliable after installation

10. Remote Control
11. Initialization
After first power on, the indicator light will be off after flashing for 20 seconds. During the
initialization, sensor is not able to detect moving objects signal. Turn on or off indicator and set the
detecting area through serial protocol.
12. Application Notice
1) The sensor should be installed by a professional electrician. Please disconnect the power before installing,
wiring or changing the setting of the dial switch.
2) Put the sensor as far as possible from large areas of metal plate, glass and other materials with high
medium density to avoid triggering by mistake.
3) Avoid using objects that vibrate for a long time around the sensor, such as a shaking head fan. The
vibration signal will be regarded as a movement signal to activate the sensor.

LIFEBEING SENSOR MSA043D 485 Version: A0

4) Avoid the detection window of the daylight sensor of the detector irradiated by an invalid light source,
which will interfere with the measurement of ambient light.
5) The product should not be too close to the wireless router at least more than 2m apart, when it is installed
and used.
6) Setting detecting area and indicator on-off by MH10.(Pressing HS in MH10 makes indicator on and
pressing LS in MH10 makes indicator off.)
7) Sensor’s microwave can penetrate wall of building. It may cause misreport when microwave penetrates
wall to detect the moving objects outside fortified area. To avoid triggering by mistake, choose suitable place
when installing, keep away from glass, plasterboard, wooden wall and other things that microwave can easily
penetrate and choose appropriate sensing parameters according to space, for examples:
A. When product is used in the room whose length and width is about 2m or less, detecting area should
be set to 25%(application scenario: washroom, sitting room )
B. When product is used in the room whose length and width is about 3m, detecting area should be set
to 50%(application scenario: washroom, hallway, sitting room )
C. When product is used in the room whose length and width is about 4m, detecting area should be set
to 75%(application scenario: small office, meeting room, library )
D. When product is used in the room whose length and width is about 5m or more, detecting area
should be set to 100%(application scenario: large office, meeting room, library )
Note: The setting detecting area depends on the actual environment( detecting area parameters above
application scenario are for reference only).
8) Hold time setting: one-person space: 1 minute to 3 minutes, multi-player space: 30 seconds to 1 minute. It is
not recommended to set a hold time of more than 5 minutes to be probably interfered by small motion signals in
the space and affect the hold time finishing.
