Entry Sensor Installation Guide


Entry Sensors defend your doors and windows. The Base Station will sound a quick chime when a door or window opens while your system is disarmed. Depending on your settings, this can also be set to trigger an alarm.

Entry Sensors are made up of two parts: a sensor and a magnet (the smaller of the two components). When these are lined up within two inches of each other, the system knows the door or window is closed. When they move more than two inches apart, the system sees it has been opened.

Prior to placing the sensor, make sure the surface has been wiped clean and has had time to dry.

Additional installation considerations:

  • If you are mounting the Entry Sensor to a metal door, we recommend placing a thin piece of cardboard between the Sensor and the Metal door.

  • If you are mounting the Entry Sensor to a magnetic door or frame, we recommended that you place the magnet on the magnetic surface.

This will ensure that your Entry Sensor has the best signal possible to communicate with your Base Station.
