Setting up your Contact Sensor

Adjust placement settings

During setup, you will be prompted to choose where you are installing your Contact Sensor. You can choose one of three placement settings, which can be adjusted later:

• Main Door:

  For doors you enter and exit from most often. When arming Ring Alarm in Away mode, you can

  customize the Exit Delay

  to allow you to exit from that door. When armed, opening the door with this Contact Sensor will trigger the Entry Delay so you can disarm your Alarm system before the alarm sounds.
• Secondary Door:

  For doors you enter and exit less often than your Main Door. When armed, Ring Alarm will sound immediately when opened.
• Window:

  For windows only. When armed, Ring Alarm will sound immediately when opened.

Installing your Contact Sensor

The Contact Sensor has two parts; the slimmer part is the magnet, and the larger part is the sensor. Install the magnet to the door or window itself, and install the sensor to the door frame or window frame. Get tips on installing your Contact Sensor on different types of door trims and window frames.

Tips for installing your Contact Sensor

• Don’t use the Contact Sensor outdoors or in environments with extreme hot or cold temperatures.
• Don’t use the Contact Sensor inside detached garages, warehouses, or sheds. Alarm devices should always be used in the same building as the Base Station.
• Don’t use the Contact Sensor near water or chemicals.

Follow these steps to physically install your Outdoor Contact Sensor:

Contact Sensor (2nd Gen)

1. Make sure the mounting surface is clean and dry before peeling the backing off of the adhesive strip.
2. Install the sensor and magnet on a door or window and frame by pressing it into place for 20 seconds.
3. Make sure there is no more than 1 in. (2.5 cm) between the sensor and magnet when the door or window is closed.

If you need to screw the Contact Sensor to the surface, you will need to use your own hardware. Use four 5 mm anchors and four 3 x 21 mm screws.

2. Make sure that the mounting surface is clean and dry before peeling the backing off of the adhesive strip.
3. Install the sensor and magnet on a door or window and frame by pressing it into place for 20 seconds.
4. Make sure there is no more than ½ in. (1.25 cm) between the sensor and magnet when the door or window is closed.

If you need to screw the Contact Sensor to the surface, use the included screws to attach the removable backplates to the mounting surface. Then, attach the Contact Sensor parts to the backplates that are mounted.
