How Do I Install a 2GIG DW20R-345?

You can install a 2GIG DW20R-345 by drilling the proper holes in the door or window and its frame. Then insert the sensor and its magnet into the holes to complete the process. The holes should be parallel to align the sensor with its magnet. Make sure to test the sensor after programming.

2gig dw20r wireless recessed door slash window contactThe 2GIG DW20R-345 is a recessed door and window contact that works using a sensor and a magnet. The sensor has a built-in reed switch that determines whether or not the device is in contact with its magnet. The sensor is normally installed inside the door or window frame, while the magnet is normally installed inside the actual door or window. The sensor requires a hole that is at least 2.6 inches deep, and the magnet requires a hole that is at least 0.5 inches deep. Both holes should have a diameter of 11/16 inches.

For best results, the magnet should be parallel with the sensor, and they should be in direct contact when the door or window is closed. This is why these sensors are commonly referred to as "contacts". When the door or window is opened, the magnet will become separated from the sensor. This will activate the sensor and have it send an alert to the security system. Remember, the system must be able to work with 2GIG 345 MHz Sensors in order to support the 2GIG DW20R-345. Compatible systems include the 2GIG GC3 and 2GIG GC2.

Complete the following steps to install a 2GIG DW20R-345:

1. Insert battery and program. Before attempting to install the 2GIG GW20R-345, you should insert a battery into the sensor. The sensor uses a single lithium CR2 battery. You will need a screwdriver or a similar thin tool to release the battery cap. With the battery inserted, you can then program it with your alarm control panel.

Most compatible alarm systems will allow you to auto-enroll the sensor. To do this, access programming, and put the system into its wireless enrollment mode. Then fault the sensor by separating its magnet to have it recognized by the system. You must then adjust any settings and configurations for the wireless zone. For more information, please see the programming guide for your panel.

2. Install the sensor. Drill an 11/16 diameter hole with a depth of at least 2.6 inches into the door or window frame. Then insert the sensor into the hole. Make sure that it is a tight fit and that the sensor is nice and secure. For a more secure installation, you can use the included screw mount contact cover with the sensor. However, this will require you to drill two separate smaller holes for screws as well. For more information, please see the "Installation Guidelines" section of the 2GIG DW20R-345 Install Guide,

3. Install the magnet. Drill an 11/16 diameter hole with a depth of at least 0.5 inches into the actual door or window. This hole should be parallel with the hole you drilled in Step 1. If the hole is not parallel, then the device may not work properly. After you have drilled the hole, insert the magnet. Make sure it is tightly fitted and secure. Unlike the sensor, there is no screw cover for the magnet, so the fit must be very tight.

4. Test the sensor. With the installation complete, close the door. Check the panel to make sure that the panel does not display a fault for the associated zone. Then open the door. The panel should display the faulted sensor. If you can fault and restore the sensor by opening and closing the door, then it was installed and programmed properly.
