How To Install The Geo-CT

The GEO-CT door/window sensor can be installed using the provided adhesive or screws. 

 Mounting Orientation: The sensor and magnet should be placed near the top of the door with the sensor attached to the unmoving part of the closure. For example, attach the main body of the sensor to the door frame, not the door. We recommend that the sensor is placed in the top corner of the opening of the door. The sensors and magnet each have a slightly engraved line. This line denotes where the sensors align to function properly. If the sensor and magnet, when together/closed, do not line up correctly, the sensor will not report correctly.  

To install the door/window sensor:

1. Select the desired position for the sensor and magnet. The sensor and magnet must be within 0.25 inches of each other on final installation. Verify that the sensor and magnet are aligned correctly. 2. Remove the sensor's battery pull tab. 3. Adhere the sensor to the wall using the provided screws and/or adhesive. We recommend using the provided screws for installation. This method is more secure than using adhesive. Using Screws
1. Locate the bottom of the sensor (the slotted short end). b. Turn the sensor over, and then gently slide a fingernail/fingertip into the slot pushing the sensor's back plate up and away from the sensor body. (You can see the FCC label on the inside of the back plate.) c. Remove the adhesive film cover. (Optional) d. Place the back plate against the door frame/windowsill, making sure that the orientation is correct for the desired position. Take note, once the adhesive is secure the sensor cannot be moved. (Optional) e. Mark the screw hole locations, then using a power drill, drill holes and install the 2 provided wall anchors. f. Insert the first screw into the non-breakaway screw hole, and then use a screwdriver to partially secure the screw in the wall. Do not fully insert the screw until the second screw has secured the sensor position. g. Insert a second screw into the breakaway screw hole, and then partially secure in the wall. h. Obsert the sensor position. When satisfied with the position, use a screwdriver to fully secure each screw in the wall. i. Press the front of the sensor against the base, until there is an audible snap. Using Adhesive
2. Select the desired position for the sensor. b. Peel one side of the adhesive tape, and then press the tape firmly against the sensor. Take note, once the adhesive is secure, the sensor cannot be moved. c. Peel the other side of the adhesive, and then press the sensor against the wall. 4. Line the magnet up with the sensor, verifying that they align properly, and then adhere the sensor to the wall using the provided screws or adhesive.

 Using Screws

1. Locate the bottom of the magnet (the slotted short end). b. Turn the magnet over, and then gently slide a fingernail/fingertip into the slot pushing the magnet's back plate up and away from the magnet body. c. Remove the adhesive's film cover (Optional), and then place the back plate against the door/window, making sure that the orientation and alignment are correct for the desired position. Take note, once the adhesive is secure, the magnet cannot be moved. d. Mark the screw hole locations, then using a power drill, drill holes and install the 2 provided wall anchors. e. Insert the first screw into a screw hole, and then use a screwdriver to partially secure the screw in the wall. f. Insert a second screw into the remaining hole, and then partially secure it in the wall. g. Observe the magnet position. When satisfied with the position, use a screwdriver to fully secure each screw in the wall. h. Press the front of the magnet against the base, until there is an audible snap. 

 Using Adhesive

1. Select the desired position for the magnet. b. Peel one side of the adhesive tape, and then press the tape firmly against the magnet. Take note, once the adhesive is secure, the magnet cannot be moved. c. Peel the other side of the adhesive, and then press the magnet against the wall. 5. Add the sensor to the panel. 6. Once added, test the sensor. Verify that when the door/window is opened that the panel notes that the sensors are faulted. Take note, testing all sensors with the GeoArm alarm monitoring station is strongly advised.
