Occupancy Sensor

Product Overview

Lutron Radio Powr Savr occupancy / vacancy sensors are wireless, battery-powered, passive infrared (PIR) sensors that automatically control lights via RF communication to compatible dimming and switching devices. 

These sensors detect the heat (IR radiation of 9.5 μm) from people moving within an area to determine when the space is occupied. The sensors then wirelessly transmit the appropriate commands to the associated dimming and switching devices to turn the lights on or off automatically. 

They combine both convenience and exceptional energy savings potential along with ease of installation.

                  OCCUPANCY/VACANCY SENSOR SETUP

                  After unboxing, follow these steps to set up the sensor.


                  Step 1

                  Hold the face of the sensor firmly and twist the base anti-clockwise to separate them.

                  Step 2

                  Unpack the battery and fit it into the battery slot on the sensor. Pay attention to its polarity.

                  A red light will appear on the Lens for 5 seconds and then go off. This signifies that your device is powered.

                  Step 3

                  Turn to the back of the sensor. There are three buttons; Auto-On, Activity and Timeout. These adjust specific properties of the sensor.


                  Auto-On: The automatic-on functionality of the sensor can be adjusted to control how the lights respond upon initial occupancy. There are three available settings: Always, Low light, and Disable.


                  • Enabled: The lights will always turn on.

                  • Low light: The lights will only turn on automatically upon entry if there is not already sufficient ambient light in the room.

                  • Disabled: This setting converts the sensor to vacancy mode. The lights will not automatically turn on but will still automatically turn off after vacancy. The lights must be manually turned on by using the associated Pico. 

                  • Activity - The sensitivity of the sensor can be adjusted based on the expected level of activity within the room. There are three available activity settings: Low Activity, Medium Activity, and High Activity (in order).


                  Low Activity: This is the most sensitive setting and will detect very slight motions. This is the recommended setting, as it will work well for nearly all applications. It is ideal for spaces where occupants will often be seated for long periods of time.

                  Medium Activity: This setting is slightly less sensitive than the Low Activity setting and can be used for spaces that experience normal activity

                  High Activity: This is the least sensitive setting and can be used for spaces that will generally only experience large motions, such as foot traffic.


                  Timeout: The sensor will turn the lights off if no motion occurs for the duration of the timeout period. There are four available timeout settings: 1, 5, 15, and 30 minutes.

                  Step 4

                  To change a setting, press and hold the button for that setting for about 5 seconds, until it’s green LED begins to flash and then release. Tap the button to move through the options. When you want to select the option, press and hold the button again for 5 seconds until the green light becomes solid and then goes off.

                  For example, to change the Auto-On option from Enabled to Disabled, press and hold the Auto-On option until it’s green LED begins to flash and then release. Tap the button twice to move to the Disabled option. Then press and hold the button again until the LED becomes solid green. Your setting has been successfully changed. To confirm, tap the Auto-On button and the LED position will indicate its setting.


                  Note:  To change the Timeout option to 1 minute, press and hold the Timeout button until it’s LED flashes green. Keep pressing the button until all 3 LED’s begin to flash and then release. The LED’s will keep flashing. This signifies 1 minute. Press and hold the Timeout button again until the LED turns solid. 


                  DO’S AND DON’TS OF OCCUPANCY/VACANCY SENSOR INSTALLATION

                  • The sensor is for ceiling use ONLY.

                  • Do not install on ceilings higher than 3.7 metres.

                  • Your installation point should be an area that has a good view of the whole room. As a rule of thumb, “if you cannot see the sensor, the sensor cannot see you”.

                  • The sensor cannot see through glass objects e.g. shower doors.

                  • Do not mount the sensor within 1.2 metres of HVAC vents, halogen or incandescent light bulbs, microwave ovens, WiFi routers (or access points) or IP cameras.

                  • Avoid placing the sensor in a location where it has a broad view outside the intended space.

                  • DO NOT paint on, or scratch the Lens.

                  INSTALLATION STEPS (RECESSED)

                  Follow these steps when installing on surfaces that can be easily cut out. An example is installing on a POP ceiling. Here, we are using a Lobby as our sample area.


                  Step 1

                  Determine the point of installation. This point should be at the centre of the lobby. Also, this should align with the lighting fixture, or any fittings on the ceiling.

                  Step 2

                  Set up the ladder under the point of installation.

                  Step 3

                  Hold the base of the Occupancy/Vacancy Sensor on the installation point and mark out with your pencil.

                  Step 4

                  With the saw blade,  carefully cut out this marked point. Do not let this point be wider than the marked point.

                  Step 5

                  Fit the base into the cut-out hollow. Ensure it is firm in the hollow.

                  Step 6

                  Fit the sensor in the base and turn clockwise till it fits into position.


                  INSTALLATION STEPS (SURFACE)

                  Follow these steps when installing on surfaces that cannot be cut out. An example is installing on a wooden ceiling. Here, we are using a Lobby as our sample area.


                  Step 1

                  Determine the point of installation. This point should be at the centre of the lobby. Also, this should align with the lighting fixture, or any fittings on the ceiling.

                  Step 2

                  Set up the ladder under the point of installation.

                  Step 3

                  Hold the base of the Occupancy/Vacancy Sensor on the installation point. 

                  Step 4

                  With your screw gun, drive in the screws through the holes provided on the base. 

                  Step 5

                  Fit the sensor in the base and turn clockwise till it fits into position.


                  TESTING THE OCCUPANCY/VACANCY SENSOR COVERAGE

                  After you have installed your sensor, follow these steps to test for coverage.


                  Step 1

                  With the sensor mounted on the ceiling, press and release the “Test” button. The lens will glow briefly, indicating the test mode has been entered.


                  Note:  There is a warm-up period of 90 seconds after the battery is installed before the test mode is activated. If the button is pressed during this time, the lens will flash continuously until the warm-up period is complete, and then the test mode will be automatically entered. 

                  Step 2

                  Confirm the coverage area by walking through the space and observing the lens. The lens will glow solid every time motion is detected. If the lens remains off during motion, the sensor cannot detect motion at that location. 

                  Step 3

                  Press and release the “Test” button again to exit the test mode. If the button is not pressed, the test mode will automatically time out 15 minutes after being enabled, or 5 minutes after the last detected motion if the room is vacated.
