12-24V DC Motion Sensor MSA001D, independent flush mounting, with silent reed switch relays

1. Features

1) Use patented 5.8GHz Low Impedance Microwave Antenna,anti wireless interference, such as Wi-Fi, Bluetooth, 5G etc.
2) Parameters can be set by DIP switch.
3) Compact size for Independent flush mounting.
4) Silent reed switch relays for some special application.

2. Function
This product is a dry contact motion sensor developed for the IoT sensing market. P1-P2 (please refer to spec) is a normally open relay, when the sensor detects human, the switch is closed. When the sensor detects no one in the environment, the relay will be disconnected after a preset hold time. So that the presence detectors system can identify whether there are people in the environment according to the state of this switch.

3. Initialization
After first power on, the light turns on and closes after 10 seconds. During the initialization, sensor is not able to detect moving objects signal.

4. Factory Settings
Detection Area: 100% Hold Time: 5s Daylight Sensor: Disable

5. 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 DIP 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 have been vibrating for a long time around the sensor, such as shaking fans, etc. The vibration signal will be regarded as the motion signal to trigger the sensor.
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 sensor should be installed at least 2 meters away from the wireless router.
6) 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).

Focus on intelligent lighting control and innovate constantly！

Core Technologies Advantages

Microwave Motion Sensor

Based on principle of Doppler effect and 5.8GHz microwave detection technology for motion detecting. Currently, Merrytek developed over 200 models motion sensors which support long detection area up to 20m, 15m mounting height and outdoor use motion sensors. Those are at the leading position in our industry.

Typical products: MC and MLC series.

LifeBeing Presence Sensor Technology

As only support big range movement detecting, microwave is normally used in the places people only make a brief stay, for example, corridor, stair well, warehouse and parking lot. Merrytek use high frequency microwave and unique programming, microwave sensors are able to detect very minor movements, i.e. typing and breathing to avoid false reporting and underreporting. Merrytek provides series sensors with KNX, DALI, 485 and Bluetooth for building automation.

Application: office, classroom, meeting room, kitchen, rest room and so on.

Typical products: MSA series.

Daylight Sensor

As always, Merrytek concentrates on simple intelligent light solutions and luminaries’ construction. We successfully completed an in depth study of our patented self-adaptive LED drivers which can identify artificial light and natural light. We therefore can supply an extremely cost-effective and energy saving daylight harvesting solution for office use.

Typical products: MS series

Flicker-free DALI/1-10V Dimmable LED Driver

Replacing traditional incandescent and fluorescent lights with more efficient and longer-lasting LED-based solid-state lighting (SSL) is an undeniable trend in the lighting industry. However, since SSL fixtures are directly connected to an AC power supply, (consistent with legacy lighting), there is a risk that 100-Hz or 120-Hz flicker could occur as a result of the driving AC current’s fluctuation at the supply's output. Flicker can make people uncomfortable, causing headaches, stress and fatigue even though the human eye may not detect the flicker.

Currently, most of dimmable LED drivers have flickering issues (especially PWM types), when dimmed below 5%. Merrytek newly-developed flicker-free dimming technology can eliminate nearly all flickering and even when dimmed to 2%.

Typical products: ML and KL series.

Emergency Pack for LED Lighting

From 2016, Merrytek has dedicated to quality emergency pack for LED fittings, such as ceiling lights, tri-proof lights, down lights and panel lights. Top quality battery will be use in all our range and make sure excellent life time and good reputation.

Typical products: KE and ME series.
