Recessed Door Contact

2GIG-DW21R-345

Operating Instructions

The 2GIG-DW21R-345 is the industry's most flexible supervised

recessed door/window contact, allowing a multitude of applications

while hiding the transmitter within a door or window frame.

The 2GIG-DW21R-345 uses a replaceable lithium battery and should

last 5 years under normal usage.

Installation & Mounting Guidelines

Programming

2GIG panels allow a tamper to be sent to 'LEARN' the serial code of the transmitter. The

2GIG-DW21R-345 sends a tamper Fault and Restore when the battery is installed. To learn the

contact into a 2GIG panel, insert the battery while the panel is in 'LEARN' mode. If inserting the

battery does not learn in the contact to the panel, use the supplied magnet to learn In the contact.

Testing

Before mounting the sensor, verify that the sensor mounting location provides good RF

communication to the panel. To verify, do the following:

1. Put the control panel into sensor test mode.

2. Hold the magnet next to the removable cap on the sensor and then pull the magnet away from

the sensor.

3. Listen for siren or keypad beeps to determine appropriate response (refer to the control panel

Installation instructions).

4. Exit sensor test mode.

Note: It is recommended that a system test be performed per the Operation & User's Guide at least

once a year.

Install the recommended battery if it is not already installed (see Battery Installation & Replacement).

Select a location on the door or window frame for the 2GIG-DW21R-345 transmitter and magnet to be

installed. Use a marker to mark and ensure that the two holes you Intend to drill are lined up directly across

from each other.

Using an 3/4" drill bit, slowly drill the first hole for the transmitter. The 2GIG-DW21R-345 was specifically

designed to be slightly larger than an 3/4" hole so you will need to carefully drill to fit by slowly routing the

hole little by little to ensure a snug fit. Use the flanged cap and use the included screws for mounting the

transmitter to the door or window frame.

Drill the matching hole for the magnet directly opposite from the transmitter in the door, also using an 3/4"

drill bit.

It is important to select the proper placement of the recessed transmitter and magnet.

The transmitter comes with two different tops, however, the screw mount is

recommended for securing the sensor to the door frame. The magnet does not have a

second top with a fiange to screw it into place so you must be extra careful to ensure

that the magnet is tightly in place once installed.

If the double screw top is used to attach the unit to the door frame, remove both screws, turn the top counterclockwise and then pull the board and battery out. Remove the old battery and replace with a new one. Use care when installing the battery and observe the correct polarity when the battery is Inserted (see Figure 2).
