【Initialization】

After power on, the sensor automatically turns on light at 100% brightness and self-check for 45s-60s. During the initialization, the sensor is not able to detect movement. It enters sensing mode after initialization, and during which, the lamp maintains at 100% brightness.

【Factory Setting】

Sensitivity: 100%, Hold time: 5s, Daylight sensor: Disable, Stand-by period: 0s, Stand-by dim level: 10%

【Application Notice】

• The sensor should be installed by a professional electrician. Please turn off the power before installing, wiring and changing parameters.
• PIR sensor can’t penetrate any materials, please make sure no obstacle between sensor and moving people/object.
• Sensor may hard to detect people if wear thick clothes in cold winter.
• Heat signals will be regarded as moving signals to trigger the sensor. Avoid facing sensor to air condition or other heating source.
• Sensor is for indoor use only. Outdoor sunlight could affect the detection of sensor.
• Due to continuous improvement, the contents of this instruction could be changed without prior notice.
• The dimming performance could be different when work with different 0-10V drivers.
• 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.
• Detection distance is related to height of people, mounting height, mounting angle, working environment temperature and etc. When ambient temperature approaches the human body temperature range (36℃~37℃/96.8~98.6℉), PIR motion detection will significantly weaken or non-responsive. When ambient temperature or LED tray temperature is higher than 55℃/131℉, false triggering may happen, please try to reduce detecting sensitivity to improve. If stays false triggering, the PIR sensor should not suitable to be used in the space.
• Given detecting area is typical value that was measured by 165cm high testers in an indoor open environment.
• 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).
• When installing in new environment, please install and test at least 5pcs product firstly before mass installation.
• PIR is a pyroelectric infrared sensor that detects changes in infrared rays. Pls pay attention to the following matters during actual use, such as: detecting heat sources other than the human body, the temperature of the heat source does not change or the heat source does not move, and other related environmental factors and violations of the PIR application principle impact.
• When detecting heat sources other than the human body due to the following phenomena, the PIR may be falsely triggered.

1. When small animals enter the detection range

2. When far-infrared rays from sunlight, car headlights, incandescent lamps, etc. are directly exposed to the sensor

3. When the temperature in the detection range changes drastically due to warm air, cold air from cold greenhouse equipment, water vapor from humidifiers, etc.

• When detecting heat sources due to the following phenomena, the PIR may not trigger

1. When there are substances such as glass and acrylic that block the transmission of far-infrared rays between the sensor and the detection object.

2. The heat source within the detection range hardly moves or moves at high speed.

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.
