【Initialization】

After power on, the sensor automatically turns on light to 100% brightness and turns off light in 45±5 seconds. During initialization, sensor is not able to detect movement.

【Factory Setting】

Sensitivity: 100% Hold-time: 5s Daylight sensor: Disable

【Application Notice】

1. Sensor should be installed by a professional electrician. Please turn off power before installing, wiring.
2. The typical installation height is 3m. It’s for indoor use only, in order to avoid false trigger by the ambient temperature. Pls do not install in locations sensitive to temperature or airflow changes, to avoid sensing failure due to false trigger or high temperature.
3. Sensors should be kept away from air conditioners, refrigerators, exhaust vents, furnaces, and other places sensitive to changes in air temperature.
4. Sensors should not be obstructed by screens, furniture, large bonsai or other isolating objects within the detection range.
5. Reflective objects should be avoided directly in front of the sensor, reflecting light will cause the sensor to be triggered incorrectly.
6. Sensors should not be installed indoors directly in front of a window, otherwise the disturbance of thermal airflow outside the window and the movement of people will cause false alarms. The sensitivity of PIR sensors to the human body is also highly related to the direction of human movement, radial movement is at the least sensitivity, while highly sensitive to the cross section direction (perpendicular to the radius).
7. The distance detect standards: At night, indoor ambient temperature of 25℃, humidity 50-70%, the human body surface temperature of 36-37 degrees, people walk in the cross-section direction at the speed of 0.6 ~ 1m / s. The maximum sensing angle of the product is based on highest sensitivity setting, if set at low sensitivity can not fulfil the maximum sensing angle. The sensing distance is related to the height of the tester, the installation height and working environment etc.
8. As PIR sensor probe is relatively fragile, pls pay attention to protection during production, storage, handling, transportation, consumer installation, and need to be gently held and put under no effective protective packaging. If the product falls may cause the infrared probe to appear hidden cracks or damage to the inner chip, then it will not work or false trigger.

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.
