Rayzeek Occupancy Motion Sensor Light Switch, 10A, US, Neutral Required


The RZ021-10A-N motion sensor light switch uses an advanced passive infrared (PIR) motion sensor to detect people in the sensor zone and integrates a photocell for daylight sensing. Users can adjust the configuration by simply pressing the two push buttons on the panel without uncovering the wallplate. Besides occupancy and vacancy mode, the RZ021 series motion sensor switch introduces an innovative manual ON/OFF mode allowing the sensor switch to be used the same as a manual wall switch so that users can have manual override and keep the light always ON/OFF as long as needed. The RZ021 series is a direct replacement for the US standard 1-Gang wall switches. A neutral wire is required for RZ021-10A-N.

  • High Load Applications: 10A version capable for loading multiple lights, fans and air conditioners
  • Versatile Sensor Mode: Occupancy(Auto-ON, Auto-OFF), Vacancy(Manual-ON, Auto-OFF), Manual ON/OFF(Manual-ON, Manual-OFF)
  • Broad Voltage: Applicable for 110V residential and 277V commercial voltage in the US.
  • Flexible Wiring: Hot wire, Load wire, Neutral wire and Ground wire. (Can be installed without a neutral wire with RZ021-10A-G)
  • Easy Installation: Fit in the US standard 1-Gang wall box

Best Commercial Grade Occupancy Sensor

The energy waste in commercial facilities is huge, to save energy is to save your electric costs. Occupancy/Vacancy occupancy sensors can save up to 50% lighting energy in conference rooms and 38% in private offices.

Occupancy sensor switches are required by code and mandatory in most commercial spaces like meeting rooms, break rooms and open offices.

The UL, FCC, RoHS certificated RZ021 series is the best commercial grade occupancy sensor switch solution for commercial usages with occupancy, vacancy and manual mode combined into one for max compatibility, flexibility and ease of use.

Built for the U.S. Market

The RZ021-10A-N series accepts voltage from 110V to 277V to fully cover the standard 120V and 270V commercial voltage supply in the U.S. market. The high 10A current rating allows it to load more lighting and electrics than competitors.

The low-profile and elegant design suits well for diverse commercial buildings.

Tested and certified by FCC, RoHS, and UL, Rayzeek strives to offer the most reliable occupancy sensor switches to our customers.

Ever meet these problems?

manual mode solution for meeting room

Lights off while in meeting

Most meetings are pretty calm without large motions. When all people sit down for a long period of time, regular sensors may not detect fine motion and turn off the light while the room is still occupied.

In this case, we have to wave hands to let the sensor detects motion to turn on the lights again. It’s a total distraction.

manual mode solution for offices

Lights still on when you leave

There are times that the occupancy sensor turns on the light even when the room is completely unoccupied. Frequent changes in heat, a fixed heat source or mirror reflection could send false singles to the sensor which causes it to turn the light on and off repeatedly.

When we cannot control the heat change, for example, the air-conditioner installed too close to the PIR occupancy sensor, then it would bring more problems than convenience.

Rayzeek has the answer!

New Feature Introduced by Rayzeek, the Manual ON/OFF 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.

motion sensor office application

Add smart automation to your office

The RZ021-10A-N is the all-around occupancy sensor switch for lighting, fans and other electrics.

Whether it’s an open office, private office, meeting room, breakroom, stairwell or corridor, the RZ021-10A-N occupancy sensor is competent for the job.

Private office

Either occupancy and vacancy mode is great for automation lighting control and energy-saving for private offices according to your preference.

With Rayzeek RZ021 occupancy sensor switch, things are never this easy. You can switch between occupancy and vacancy mode at any time. If you enjoy natural light, setting occupancy mode with ambient light will keep the light off in the daytime. Or set the switch to manual mode when you need it to be always on or off.

Conference room

Unlike offices, conference rooms or meeting rooms are not used quite often. Vacancy mode is recommended here as it requests to manually turn on the light which can prevent false-on and save more energy.

With the innovative manual on/off feature, you can have the lighting always on the whole meeting without any unwanted false-off.

Save energy with Rayzeek in under 8 minutes.
