LDHD2AZW Installation Guide
The LDHD2AZW is designed to secure the perimeter of the residential premise and provide the ability to
add various automation services. The LDHD2AZW, which consists of a sensor and a magnet that
attaches to a door or window, will communicate door or window events to the home security system.
When the magnet is moved away from the sensor, a signal will be sent to the control panel that
communicates the changed state to the security system. Signals can also be used to activate a chime or
convenience lighting based on system settings.
The LDHD2AZW is designed to be installed indoors only.
The LDHD2AZW is compatible with the following Touch Screen: Technicolor TCHT2AA0.

Introduction
Specification

The LDHD2AZW needs to be paired before installation.
1. While next to the home controller or security system,
slide the top cover open to expose the battery pull tab, pull
the plastic tab to activate the sensor, slide the top cover to
the closed position (Figure 1).
2. The LED indicator will be lit green for two seconds
while the device is booting.
3. Once booted the LED will blink green three (3) times
every five (5) seconds while scanning for a network.
4. If a network is not found after approximately ten (10)
minutes, the sensor will go into sleep mode. To restart the pairing process, tamper the sensor by
sliding the battery cover open and then closed or create a zone event by placing the magnet near the
sensor and then move it more than 3" away from the sensor.
5. Once the device has been discovered by the controller the sensor will need to be faulted or restored
using the magnet in order to complete the enrollment.
6. After the sensor is successfully paired to the home controller or security system it is ready for
installation. Follow the steps in the installation section.
NOTE: The LDHD2AZW is for indoor use only –it MUST be installed indoors.
NOTE: This LDHD2AZW shall only be installed on painted wood and steel surfaces for UL
applications.
1. Once paired the LED will blink either a red, green, or amber color providing a visual indicator of the
communication performance with the home controller or security system. Move the sensor to the
intended location of installation. If the LED is slowly blinking green you have good communication
with the home controller or security system and can proceed with the remainder of the installation
process. Double-blinking amber indicates the sensor can communicate, however, look at improving
the communication by alternating the location of the sensor on the door or window. Fast blinking red
indicates the sensor cannot be installed at this location.
Note: The LED will illuminate for three (3) minutes after the initial pairing process. If additional
time is needed to position the sensor, slide the top cover open and then closed and the LED will
illuminate for an additional thirty (30) seconds.
2. Please make sure that the sensor and magnet is located less than 0.25" from each other. For optimal
performance, it is highly recommended to install the LDHD2AZW on the fixed frame and the
magnet on the moving part of the door/window. Place
the sensor near the top of the door/window close to the
opening edge of the door/window. When mounting the
sensor and magnet ensure the marks on the sensor and
magnet are aligned (Figure 2). The LED on the sensor
should be positioned at the top when possible. Ensure
you have space to slide open the battery door when
positioning the sensor.
3. Peel the paper off one side of the double-sided tape provided, attach to the back of the sensor and
press firmly for a few seconds. Then peel the paper off the back of the sensor and position the sensor
to the door/window fixed frame. Be sure to position the sensor in the location you have verified to
provide good communication with the home controller or security system. Press firmly with 15 psi
for a few seconds.

4. When mounting the magnet, add spacers as necessary to ensure the back of sensor and magnet are on
the same plane. Peel the paper off one side of the double-sided tape provided, attach to the back of
the magnet or spacer and press firmly for a few seconds. Peel the paper off the back of the magnet or
spacer, align the magnet to the sensor and press firmly for a few seconds.
1. The LED on the sensor will remain off during normal operation.
2. The sensor is equipped with a tamper switch. Sliding the battery cover to the open position will cause
a trouble fault on the home controller or security system. Upon closing the cover, the trouble will
clear, and the communication test will run for thirty (30) seconds. Refer to the Installation section for
details on this feature.
If the sensor needs to be factory defaulted (for example, to prepare it for re-joining with a home
controller or security system):
1. Enter the home controller or security system and use the device menus to delete the sensor that
requires a factory reset.
2. Slide the battery cover to expose the battery and the
reset release button (Figure 3).
3. Depress the small reset release button while
continuing to the slide the battery cover until you
expose the red reset text. You may need to use a small
screwdriver or paper clip to press the release button as
shown in Figure 4.
4. Remove the battery, wait ten (10) seconds, and then
re-insert the battery.
5. Once the battery is installed wait until the LED turns green
then immediately slide the battery cover closed.
6. The factory reset process will take approximately one (1)
minute, during this time the LED will remain solid green.
7. Upon completion of the factory reset the LED will blink
green three (3) times every five (5) seconds indicating it is
ready to be paired.
If the home controller or security system indicates the battery is low, the battery must be replaced.
1. Purchase a CR2 Battery.
2. Once you have received the CR2 battery, slide the
battery cover to expose the battery as shown in Figure
5, remove the old battery, wait ten (10) seconds, and
install the new one.
3. Once the battery is installed, slide the battery cover to
close the device. The LED will illuminate green for
two (2) seconds and will automatically reconnect to the home controller or security system and
return to normal operation.

4. If the LED remains green or blinks three (3) times every five (5) seconds, it is an indication that the
device has been disconnected from the home controller or security system. To resolve this state, the
device must be deleted and then installed again to the home controller. If you do not have the ability
to execute these steps, contact support at 1-800-xfinity.
If the device has trouble with pairing to the home controller or security system try the following steps:
1. Open then close the battery cover to trigger a tamper and re-start the pairing process.
2. If the device continues to have trouble pairing, remove the battery for ten (10) seconds and then re-
insert it.
3. If the device continues to have trouble pairing, use “Reset to Factory Defaults” procedure to attempt
pairing again.
If the device was communicating with the home controller or security system but is no longer
communicating, try the following steps:
1. If the device has been in use for months or years and the failure is sudden, check the controller to see
if the device has a low battery. Follow the instructions provided for replacing the battery.
2. Trigger a tamper by opening and closing the battery cover. If the LED is blinking RED it is an
indication that your sensor can no longer communicate with the home controller or security system
due to changes in your RF environment. Install a repeater so the system's range can reach the desired
location for the sensor.
3. Perform a Factory Reset and then Re-pair the sensor as indicated in the steps above.
