How to Mount a Security Motion Sensor

Security motion sensors come in two basic types; hardwired and wireless. The fundamentals for mounting motion sensors are the same no matter which type of sensor you install. Remember that most motion sensors detect heat so you should not mount a motion sensor near anything which changes temperature quickly such as a large heat vent. Motion sensors must have a source of power so you will need to provide power to the device or use a battery-operated sensor.

Things You'll Need

  • Regular screwdriver
  • Phillips screwdriver
  • Drill and bits (depending on surface motion detector is mounted to)
  • Four conductor 22-gauge wire (for hardwired sensors)

Instructions

  1. Hardwired Sensor

    • 1

      Run the wiring from the alarm system control panel to the location of the motion sensor.

    • 2

      Remove the cover on the front of the sensor and mount the sensor to the wall using the screws provided.

    • 3

      Connect the wiring as per the instruction that came with the sensor. You will connect the positive voltage and the ground wire to the sensor power terminals (do not reverse these as you can damage the unit) then connect the two sensor wires to the sensor terminals. Replace the cover.

    • 4

      Unplug your system and disconnect the backup battery. Connect the motion sensor wires to the control panel terminal (make sure you do not reverse the negative and positive wires).

    • 5

      Reconnect the battery and power to the system. Walk the room while watching the red indicator light to ensure the sensor picks up motion in the area you are trying to cover.

    Wireless Motion Sensor

    • 6

      Remove the backing plate from the motion sensor by pressing the retaining tab and sliding the back off.

    • 7

      Mount the backing plate to the wall.

    • 8

      Install the battery, enable the motion indicator light and slide the motion sensor into the backing plate. Walk the room while watching the red indicator light to ensure the sensor picks up motion in the area you are trying to cover.

    • 9

      Remove the unit from the backing plate, disable the indicator light and replace the unit on the wall.
