Recessed Door/Window Sensor
Written by Cath Smith
Updated over a week ago

The Recessed Door/Window Sensor is a small door sensor that is installed within the door and door frame, and is concealed for a discrete aesthetic. The Recessed Sensor monitors the opening and closing of the door. When the door opens, the magnet moves away from the sensor, causing the device to transmit a door open signal to the Abode hub. When the door closes and the sensor detects the magnet again, it will transmit a door close signal. This sensor is a powerful home security and home automation device. Use it to trigger burglary alarms and trigger CUE Automations to enhance your smart home.


Parts Overview


1. Pairing Button (Used when adding the device to the Abode Hub, and for placing the sensor into a test mode for 3 minutes. Use a thin tool like a paperclip)
2. LED Status Light (flickers when pressing the Pairing Button)
3. Mounting Holes (2x screws are included)
4. Battery Tab Sensor
5. Magnet

LED Status Light Guide

In the Normal operation mode, the LED status light remains off except in the following situations:

  • When the Pairing Button is pressed (LED flickers)

  • When the sensor battery is low

  • When the battery is exhausted, the sensor will stop all function and the LED will flash every 4 seconds

Pairing Guide

1. Make sure you have the latest version of the Abode App installed on your mobile device. In the Abode App on your iOS or Android device, select the Menu (≡).

2. Tap "+ Add Device" from the list.


3. Tap "Door & Window Sensors".


4. Tap "Recessed Door Sensor".


5. Pull out the battery tab from the Sensor Body, then tap "Continue".


6. Press the pairing button one time using a thin tool (like a paper clip). The red LED will flicker and the device will be added.


7. The last page will ask that you name your new sensor, then your Recessed Door Sensor will be paired and ready to use.

After pairing the Recessed Door Sensor with the hub, you can perform a simple test by placing the Magnet over the exposed end of the Sensor Body. When you pull the magnet away from the sensor you should hear the hub chime if sounds are enabled, and a door open event appear in the Timeline of the Abode App. This can be useful when choosing the location to install the sensor so that the sensor is installed within wireless range of the Abode hub.

Installation Guide

Installation TipsAvoid mounting the sensor near metal objects such as door locks and metallic door frames that could possibly cause the magnet to malfunction. When mounting the door sensor and the magnet, make sure both are aligned to each other to allow optimal opening/closing detection. The distance between the door sensor and magnet when the door is closed should be no more than 0.50 inch (12.7mm).1. Make sure your sensor battery tab has already been pulled and the device is paired with your Abode hub. See Pairing Guide above for pairing details.

2. Use a 0.75 inch (19mm) drill bit to drill a 2.75 inch (70mm) deep hole into your door frame for Recessed Door Sensor Body (the large of the two components). We recommend using a paddle-style drill bit.


3. Use a 0.75 inch (19mm) drill bit to drill a 0.60 inch (15mm) deep hole into your door for the Sensor Magnet.

4. Insert the Sensor Body into the door frame, then secure it in place using the two included screws through the two screw mounting points. Use a Philips screwdriver to tighten. If your door frame material is dense you may need to drill two small pilot holes that are smaller in diameter than the included screws. Refer to the visualization below showing installation of Sensor Body within door, screw placement, and Magnet installation.


5. Insert the Sensor Magnet firmly into the drilled hole on the door. You may need to used a rubber mallet to gently tap the Magnet into place. Mounting is now complete.

Battery Guide

The Recessed Door Sensor is powered by 1x 3V CR2 lithium battery. When the battery is low, a low battery signal will be sent to the Abode Hub along with the regular transmission. The LED Indicator will light up when the sensor is activated under low battery status. When the battery is exhausted, the device will stop all function and the LED will flash every 4 seconds.

Changing the Battery

1. Remove the door sensor main body from the door frame.

2. Open the top cover by using a flat-head screwdriver and turn to the left as indicated by the open arrow on the cover.


3. Withdraw the internal component and remove the old battery.

4. After battery has been removed, press in the pairing button a several times to fully discharge the components before inserting new battery.

5. Insert a new 3V CR2 Lithium battery into the holder.

6. Align the internal components board so that it easily slides into the plastic casing.


7. Close top cover and turn clockwise using a flat-head screwdriver until the latch marks align.
