3. Functions

Movement signals active Slight motion& Breathing signal maintain

The sensor detects human walking, slight motion(such as body movement, turning the head, and other minor movements), and breathing to realize the detection of human existence in a non-sleep state.

* Movement signal: Big movement for sensor triggering within the detection area.

* Slight motion signal: very small movement can be collected within the detection area, for example: leaning forward, leaning back, body swinging, shaking his head, typing, playing with mobile phones, and other small behavioral actions.

* Breathing signal: Detected breathing signal (abdominal cavity and chest cavity dilation behavior)

9. Remote Settings

Remote control settings only support sensitivity, delay, ON/OFF, reset, sensor motion, and indicator switch settings.

10. Initialization

When the first power is turned on, the sensor enters the self-test mode, and the self-test will be completed after 20 seconds to enter the normal working state. During the initialization, the external motion signal will not be detected, remote control signal will not be received.

13. Application notice

1. The product should be installed by a professional electrician.

2. The product should be kept as far away as possible from large-area metal plates, glass, and other substances with high medium density to avoid false triggering.

3. The antenna surface of the product and its nearby circuits should avoid the flow of large currents, so as not to affect the normal operation of the product.

4. When installing multiple products in one place, please try to ensure that the antenna surfaces of the products are parallel to each other and do not face each other. The installation distance between products should be greater than 1m. Dense installation may cause false reports.

5. The antenna surface of the product should avoid facing the AC drive power supply, and stay away from the rectifier bridge, transformer, switch tube, and other high-power devices of the drive power supply, so as to avoid power frequency signals from interfering with the microwave module.

6. Avoid using objects that vibrate for a long time around the product, such as shaking head fans and so on. The vibration signal will be regarded as a moving signal to trigger the product.

7. Avoid unnecessary lights illuminating the product's illuminance sensor detection window and interfering with the measurement of ambient light.

8. The microwave sensor has an ability to penetrate the building wall, and the microwave that penetrates outside the wall may cause false triggering when it detects moving objects. In order to avoid false triggering, when installing, please choose an appropriate detection area, for example:

A. When the product is used in a room whose length and width are about 2m or less, the detection area should be set to 25%(application scenes: washroom, sitting room ).

B. When the product is used in a room whose length and width are about 3m, the detection area should be set to 50%(application scenes: washroom, hallway, sitting room );

C. When the product is used in a room whose length and width are about 4m, the detection area should be set to 75%(application scenes: small office, meeting room, library );

D. When the product is used in a room whose length and width are about 5m or more, the detection area should be set to 100%(application scenes: large office, meeting room, library ).

Note: The setting detection area depends on the actual environment( detection area parameters above application scenes are for reference only).

9. The detection distance is related to the moving speed of the moving object, the size of the moving object, the installation height, the installation angle, whether the installation environment is empty, the material of the reflector, and other factors. The detection distances given in the specification are typical values, which are obtained by testers at a height of 165cm and a weight of 65 kg, and tested in an indoor open environment.

10. Product specifications and parameters may be optimized without prior notice.

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.
