Nortek Security and Control 2GIG DW21345 User Manual

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

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.

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

1

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

2

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

3

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"

4

drill bit.

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.

CAUTION:

Do not apply any pressure
on the glass reed switch

door frame

Battery Installation & Replacement

Use a screw driver to turn and open the top of the 2GIG-DW21R-345 to change tops or access the battery. 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). Use only the recommended
replacement batteries (see Specifications). DO NOT APPLY PRESSURE ON THE GLASS REED SWITCH.

WARNING! The polarity of the battery must be observed, as shown (see Figure 2). Improper handling of
lithium batteries may result In heat generation, explosion or fire, which may lead to personal injuries.
Replace only with the same or equivalent type of battery as recommended by the manufacturer (see
Specifications).

Batteries must not be recharged, disassembled or disposed of in fire. Disposal of used batteries must be made in

accordance with the waste recovery and recycling regulations In your area.

Keep away from small children. If batteries are swallowed, promptly seek medical attention.
