Registering the sensor

• This procedure is not required for devices that were included as part of a bundle.
• Before you can use the sensor, it must be registered with the hub.
• If you purchased devices separately (i.e., not as part of a bundle), you must register each device to the hub.
• You can register each device by using the registration buttons or the [Home Network] app.

Using registration buttons 

1. Hub:
   Press and hold OTHER DEVICEN until the LED indicator blinks slowly in green.
2. Sensor:
   Remove the front cover, and then press and hold until the LED indicator blinks slowly in green (page 8).
   When registration is complete, the hub sounds one long beep.
   Note:
   To cancel without registering the sensor, press on the hub and on the sensor again.
   If registration fails, the hub sounds several short beeps.

Using the app
When you register the sensor by using the [Home Network] app, you can assign it a name and location. For more information, refer to the User’s Guide (page 16).

Information about sensor features

The garage door sensor utilizes an accelerometer to detect its orientation. Please read the following information before deciding where to install the garage door sensor.

Note:

• The sensor is not designed to be used in situations that require high reliability. We do not recommend d the use of the sensor in these situations.
• Panasonic takes no responsibility for any injury or damage caused by the use of the garage door sensor.

Compatible garage doors

How an open door is detected
The sensor is installed by mounting it to the interior side of your garage door. It should be mounted in such a way that it is perpendicular to the ground when the garage door is closed, and is tilted when the garage door is opened. When the garage door has opened far enough to tilt the sensor beyond the detection threshold (page 17), the sensor is triggered.

Note:
The sensor is not triggered if the door is opened slightly.

1. Door closed
2. As the door opens, the sensor is triggered
3. Door fully open

Confirming the usage area

Wireless communication range
The wireless communication range of each device in the system from the hub is approximately 50 m (160 feet) indoors and approximately 300 m (1,000 feet) outdoors. Wireless communication may be unreliable when the following obstacles are located between the hub and other devices.

• Metal doors or screens
• Walls containing aluminum-sheet insulation
• Walls made of concrete or corrugated iron
• Double-pane glass windows
• Multiple walls
• When using each device on separate floors or in different buildings

Note:
You can check the sensor’s communication status by pressing.  I the LED indicator is lit in green or red, the sensor is communicating properly with the hub. If the LED indicator blinks in red, it is out of range of the hub.

Usage area cautions
Using the sensor in the following areas may cause deformation, malfunction, or operational failure. 

• In direct sunlight 
• Areas exposed to grease or steam, such as kitchens
• Near fire or heating devices
• Near magnetic fields (such as near microwaves and magnets) R,, Areas subject to extreme temperature changes, such as next to air conditioners

Mounting the sensor

In most cases, you can mount the sensor to the garage door using double-sided tape. In some cases, such as when mounting the sensor to a wooden surface, you can use screws.

Installation precautions

• Observe the following to avoid the risk of falling, which could cause injury or damage to property.
• Mount the sensor on a stable surface where the sensor will be adequately supported.
• Do not mount the sensor on plywood less than 25.4 mm (1 inch) thick.
• Install the sensor on the inside of he garage door.
• Mount the sensor near the top of the garage door. Additionally, we recommend mounting the sensor near the left or right edge of the garage door, so that the sensor is not directly above the car when the garage door is open.

Securing with double-sided tape

Important:

• Make sure the surfaces of the mounting adaptor and the installation area of the garage door are clean and dry before applying double-sided tape. Take particular care to remove any oil or grime that has accumulated on the garage door.
• Install the sensor on a smooth area of the garage door. Ideally t,,  here should be no pits or grooves deeper than 0.5 mm (0.02 inches).
• Once you have used the double-sided tape, do not reuse it.  When mounting the sensor in cold temperatures, observe the following to ensure optimal adhesion.
• Affix the double-sided tape to the mounting adaptor indoors, when the tape and the adaptor are at room temperature.
• Use a hair dryer or other low-heat emitting device to warm the installation surface of the garage door immediately before adhesion; otherwise,, adhesion may be poor and the sensor may fall.
  1. Make sure that the front cover and the mounting adaptor are firmly attached to the sensor.
  2. Affix the double-sided tape to the mounting adaptor.
     Make sure the tape covers the screw holes on the mounting adaptor.
  3. Attach the sensor to the inside of the garage door.
     Make sure the mounting adaptor release lever is facing down when the garage door is closed.
  4. Press firmly to ensure solid adhesion to the installation surface.

Removing when secured with double-sided tape

1. Tie a piece of thread to two sticks, screwdrivers, etc.
2. Pull the thread tight and use it to cut the double-sided tape, and then remove any excess tape (A).

Securing with screws

Important:
Make sure the screws are shorter than the thickness of the installation surface.

1.  Remove the sensor from the mounting adaptor by pressing the release lever (A), sliding the sensor u,,p and lifting it away from the mounting adaptor (B).
2. Use the screws to attach the mounting adaptor to the inside of the garage door.
   Make sure the “UP” mark on the mounting adaptor points upwards when the garage door is closed.
3. Attach the sensor to the mounting adaptor.
   1. The sensor will click into place when it is secured.
   2. Make sure the “UP” marks on the back of the sensor and the inside of the mounting adaptor point in the same direction.
