Door & Window Sensor


We’ve created a detailed tutorial explaining how to change the batteries. Click here to view it.
Keep in mind that every door sensor has two parts: the bigger sensor box and a smaller magnet part. If those parts are any farther than a half inch apart when the door is closed, then the door will read as open. If this is an issue, you can remove the magnet part and remount it. If you feel you might need to move it more than you are comfortable, contact our Customer Care Team via Chat for assistance.
You can bypass most sensors on your system so that you can still use the door or window that you want while the system is still armed. What this does, is turn off monitoring for that sensor until you disarm or re-arm your system. To learn how to bypass a sensor, click here.

Yes, cold weather can affect the life-span of your batteries. Even within the recommended temperature range, battery performance can still be impacted. Batteries will discharge less efficiently as the temperature decreases, resulting in low battery alerts. Also know that batteries have lower operating temperature capabilities than the equipment pieces themselves. We suggest changing them at the beginning of the season if you live in an area with extremely cold temperatures.
A recessed door sensor is drilled into your door. Once the door sensor is installed, you will only see a little circle in the door and door jamb. A door/window sensor has a small box and contact magnet that is mounted on the door and door jamb.
The panel will tell you if any of your sensors have a low battery. A notification will appear on the panel letting you know it’s time to change. We created a detailed tutorial explaining how to change the batteries, click here to view it.
