4. Wiring

Remarks:

1. Our sensor is recommended layout in UPS circle to guarantee instant smart scene execution or electrical appliance operation

2. LN terminal stands for AC input, and L’N’ stands for AC output, please wire correctly

3. One sensor’s max loading capacity is 800w resistive loading and 400w inductive loading for one single load. if you want to connect more load in one loop, we recommend adding an AC contactor in our output LN terminal to avoid momentary surge overload.

5. Initialization

When powered on, the sensor indicator will turn off after flashing for 20 seconds and will not detect a moving signal during this time. After 20S, you can use our MH15 remote to adjust detection area, hold time, daylight sensor, etc parameters.

6. Factory default setting

Detection Area:100% Hold Time:5s Daylight threshold: Disable

8. Function Description

1,MSA224 RF can control electrical load like lighting independently or do master-slave group control, below is its detailed function instruction:

If the wireless network all consists of MSA224 RF A and they’re assigned to the same channel work as broadcast mode, then any triggered sensor will trigger other sensors

2, If some MSA219 RF A is set as master and some MSA224 RF A or MSA058 RF is set as a slave in the same channel, then only master MSA219 RF A can work as TX, slave can only work as RX

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.
