6. Structure and installation

7. Installation

Note: Sensor antenna should be above LED tray at least 2mm.

8. Radiation pattern

*When installed at 6m height, sensor with 50% detection area is unable to detect motion signal.

9. Initialization

After power on, the sensor automatically turns on light at 100% brightness. After 10sec, it turns low brightness. During the initialization, the sensor is not able to detect movement.

10. Factory Setting

Detection area: 100%, Hold Time: 5S, Stand-by Period: 0S, Stand-by dim level: 10%, Daylight Sensor: Disable

11. Application Notice

(1) The sensor should be installed by a professional electrician. Please turn off the power before installing, wiring or changing parameters.

(2) Microwaves cannot penetrate metal. Do not place the product in a closed metal lamp or a half-closed metal lamp and metal or glass are not allowed to cover above the product. If antenna needs to pass through the metal plate, please ensure that the top of the sensor is close to the metal plate.

(3) The distance between any inductive sensors should be greater than 2 meters. Keep sensor away from switches, routers and other wireless devices to avoid radio interference, more than 1.5 meters. The antenna surface of the microwave module should not be directly facing input AC and output DC to avoid low or high frequency signals affect the normal operation of microwave sensor’s antenna.

(4) Vibration signals will be regarded as moving signals to trigger the sensor. Avoid using objects that vibrate for a long time around the sensor, such as large metal equipment, pipes, air conditioning outlets, exhaust vents, smoke exhaust machine ports, shaking fans, etc. Pets in detecting area may trigger sensing.

(5) Sensor is for indoor use only. The waterproof effect for outdoor use will be affected. Wind, rain, and moving objects around will cause false triggering. When the sensor is installed in a metal lamp, metal reflective surface, or a narrow enclosed environment, the microwave will be reflected repeatedly and cause false triggering. Please reduce the sensitivity or contact the manufacturer for technical support.

(6) This Sensor is suitable for ceiling mounting. If wall mounting, the microwave detection distance will be greatly increases, which may lead to the phenomenon that the microwave passes through the wall or does not turn off the lamp. Please adjust the sensitivity by 50%. If 50% cannot be used, please avoid wall installation or contact the manufacturer to provide technical support.

(7) Due to continuous improvement, the contents of this instruction could be changed without prior notice.

(8) Different PWM drivers, different low brightness. The daylight threshold is measured in a sunny environment without shadow and ambient light diffuse reflection. Ambient lux level could be different in different environment, weather, climate, time-of-day and season.

(9) Sensitivity distance is related to moving speed of objects, size of moving objects, mounting height, mounting angle, working environment, reflecting materials etc.

(10) Given detecting area is typical value that was measured by 165cm high testers in an indoor open environment.

(11) This product have to use with voltage-stabilized DC power supply whose input voltage is stable and ripple factor is low(ripple factor is lower than 100mV; load current is greater than 25mA).

(12) When installing in new environment, please install and test at least 5pcs product firstly before mass installation.

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.
