Wall Mount Occupancy Sensor Switch, US Standard, 10A, No Neutral Required

Model: RZ021-10A-G Categories ,

The RZ021-10A-G(without Neutral wire) is an US style 10A wall mounted occupancy sensor switch which uses advanced passive infrared sensor(PIR) and MCU control. Compared to traditional motor sensor, it can automatically turn lights or fan on/off by detecting heat emitted from the motion, and have better stability and energy saving performance.

Function: Occupancy, vacancy, manual mode all-in-one
Main Spec: 110~277V, 10A, ground required, US standard
Certification: FCC, RoHS certified, UL listed

Incredaiblly versatile

The Versatile Rayzeek021-10A-G combines occupancy, vacancy and manual mode into one motion sensor wall switch for energy efficiency, convenience and compatibility.

With Rayzeek occupancy sensor light switches, you will never have to worry about looking for the light switch in the dark, forgetting to turn off the light wasting energy or having difficulties turning on the light with arms-full.

The all-round occupancy sensor switch is capable of nearly every residential and commercial application.

Unmatched sleek design

Regular 2-in-1 occupancy/vacancy sensor switches are thick and bloated. They contain mechanical dials and switches inside the panel cover for adjusting modes and settings.

Rayzeek occupancy sensors are smartly designed without any unnecessary dials or switches, all modes and settings can be adjusted by simply pressing the big and small buttons on the panel with light indicators.

The super-flat, low-profile and elegant design can fit any decor of residential and commercial applications.

Ever meet these problems?

manual mode solution for air conditioner

Lights constantly turning on and off near air-conditioner

Sudden heat change or a fixed heat source like HVAC can send distraction singles to PIR motion sensors.

In real-life cases, the air conditioner and motion sensor switches are already installed properly near each other and unable to change position, regular PIR motion sensors could be a problem by turning the light on and off randomly due to the detection of heat change.

Optimal motion sensors should always bring convenience to people, not trouble.

Lights keeps on when room unoccupied

Similar to heat change, mirror reflection can also send false singles to PIR motion sensors to keep the light on even when the room is totally unoccupied.

Instead of finding the source and reduce the mirror reflections, which is usually relatively complicated, we need a smarter way to fix this problem.

The ultimate solution

Manual ON/OFF mode to bypass sensor mode

Rayzeek introduces a new feature to solve the problems in the above scenarios, the manual on/off mode, which can turn the occupancy sensor into a manually controlled sensor temporarily without changing the sensor’s setting and working mode.

To enter the manual on/off mode, short press the small button in the panel, the sensor will now work as a manual-controlled switch. In this mode, the sensor switch is similar to a mechanical switch, you can turn the light on/off by short pressing the small button. The sensor will still flash a red indicator light when motion detected but it will not control the lighting.

To switch back to the previous mode, short press the big button, it will work as a regular occupancy sensor again. All settings like working mode, light, and time-delay still remain the same.
