2GIG DW20R - Wireless Recessed Door/Window Contact Reviews
Submitted on 11/19/2019 Alarm Grid
The 2GIG DW20R is a recessed 345 MHz contact designed for use with 2GIG Security Systems. It is also compatible with the Honeywell Lyric Alarm System (MR3 or higher) and the 345 MHz version of the Qolsys IQ Panel 2 Plus. As a recessed sensor, it is hidden from view once installed. This allows for an aesthetically pleasing installation. The sensor is also very easy to use, and it works very well. However, it is more difficult to install than a surface-mounted sensor. All things considered, we give it 5 Stars.
Many users prefer to use recessed contacts with their doors and windows so that they are hidden and out of view. While these devices are not as popular as the easier-to-install surface-mounted sensors, there are many users who won't mind going through the extra trouble to use these devices. The device is quite simple to use. When the magnet separates from the sensor, a metal reed switch inside the sensor becomes released. This tells the sensor to report to the security system. We also like the fact that the sensor is compatible with a good selection of systems.
There are some negatives of the DW20R which must be mentioned. For one, it is more challenging to install than a surface-mounted sensor as holes need to be drilled. The sensor itself needs 2.6 inches of depth, which is fairly deep for a recessed contact. Meanwhile, the magnet requires 0.5 inches of depth, which isn't too much, but it might be impossible for certain windows. The sensor is not designed for use with steel doors and windows, which somewhat limits its versatility. The DW20R also has somewhat of a lackluster range, as it is recommended to use the device within 100 feet of the panel. However, the sensor can technically work from up to 450 feet away in open air.
Although the 2GIG DW20R has its flaws, it is still a very good contact. We give it 5 Stars.
Good: Hidden From View, Easy to Use, Good System Compatibility
Bad: Requires Drilling Holes, Large Sensor, Not For Steel Doors/Windows, Weak Range
Bottom Line: 5 Stars
