AJAX GlassProtect User manual

Glass Protect User manual
Glass Protect is a wireless indoor glass break detector recognizing the
sound of shattering the glass at a distance of up to 9 meters. Glass Protect
can operate up to 7 years from a pre-installed battery and has a socket for
connecting a third-party wired detector.
Glass Protect connects to the Ajax security system via the
protected Jeweller radio protocol. The communication range is up to 1,000
meters in line of sight. Also, Glass Protect can be connected to third-party
security systems using the Ajax uart Bridge or Ajax oc Bridge
Plus integration modules.
Users can configure Glass Protect via the Ajax app for mac OS, Windows,
iOS, or Android. The system notifies users of all events through push
notifications, SMS, and calls (if activated).
The user can connect the Ajax security system to the central monitoring
station of a security company.

the tamper in case of any attempt to dismantle the detector. Don’t break it
out!)
4. External detector connection socket
5. QR code
6. Device switch
7. Tamper button

Operating Principle
Glass Protect uses a sensitive electret microphone to detect the sound of
glass breaking, consisting of a low-frequency hit sound and high-frequency
crashing sound of glass shatters. Such two-stage glass break detection
decreases the risk of false triggering.
Glass Protect detector does not react to the breaking of the film-covered glass: shockproof,
sunscreen, decorative, or any other type of film. To detect the breaking of such kind of glass, we
recommend using the Door Protect Plus wireless opening detector with shock and tilt sensors.
If triggered, Glass Protect immediately transmits the alarm signal to
the hub, activating the sirens (if connected) and notifying the user and
security company.
Connecting
Detector Connection to hub
Before starting connection:
1. Following the hub user guide, install the Ajax app. Create the account, add
the hub, and create at least one room.
2. Switch on the hub and check the internet connection (via Ethernet cable
and/or GSM network).
3. Make sure that the hub is disarmed and does not update by checking its
status in the Ajax app.
Only users with administrator rights can add the device to the hub.

Pairing the detector with hub:
1. Select Add Device in the Ajax app.
2. Name the device, scan or type the QR code (located on the detector body
and packaging), and select the location room.
3. Tap Add —the countdown will start.
4. Switch on the device.

For detection and pairing to occur, the detector should be located within the
coverage area of the wireless network of the hub (at a single protected
object). The connection request is transmitted for a short time: at the
moment of switching on the device.
If the device failed to pair (LED blinks once per second), switch it off for 5
seconds and retry. The detector connected to the hub appears in the list of
devices in the app. The update of the detector statuses in the list depends
on the device ping interval set in the hub settings (the default value is 36
seconds).
Connecting to Third-Party Systems
To connect the detector to a third-party central unit using
the uartBridge or ocBridge Plus integration module, follow the
recommendations in the user manual of the respective device.

Functionality testing
The Ajax security system allows conducting tests for checking the
functionality of connected devices.
The tests do not start immediately but within a period of 36 seconds when
using standard settings. The test time start depends on the settings of the
detector scanning period (the paragraph on “Jeweller” settings in hub
settings).
Detector functionality testing
Having defined the location of the detector and having fixed the device with
the bundled adhesive tape, test the detection zone.
Glass Protect does not react to clapping!
Testing the detector
Hit the glass with your fist without breaking it. If the detector catches a low-
frequency sound, the LED blinks. Simulate a high-frequency glass
shattering sound for 1.5 seconds after the first hit with a special tool or
hitting a glass with a metal object. After recognizing the sound, the detector
switches off the LED indicator for a second.
To be triggered when the system is armed, the detector needs to recognize sounds in the
following order: low-frequency sound (hit) firstly, then high-frequency sound (glass shattering,
shards). Otherwise, the alarm will not go off.
Switch on/off all the appliances that usually operate in the room:
generators, air conditioners, etc. If this triggers the detector, try to change
the sensitivity or relocate Glass Protect.
Use the sensitivity level, at which the detector correctly passes both test
stages and does not respond to any devices operating in the room.

Installing the device
Selecting the Location
In some cases, the household activity can cause false alarms
The location of Glass Protect depends on its remoteness from the hub, and
obstacles hindering the radio signal transmission: walls, floors, large
objects inside the room.
Check the Jeweller signal level at the installation location
If the signal level is low (one bar), we cannot guarantee the stable
operation of the detector. Take all possible measures to improve the quality
of the signal. At least, move the detector: even a 20 cm shift can
significantly improve the quality of signal reception.
If the detector has low or unstable signal strength even after moving, use
a ReX Radio signal range extender.
Do not install the detector:
1. outside the premises (outdoors);
2. nearby sirens and speakers;
3. nearby any metal objects or mirrors causing attenuation or screening of the
signal;
4. at any places with fast air circulation (air fans, open windows or doors);
5. inside premises with the temperature and humidity beyond the range of
permissible limits;
6. Closer than 1 m to the hub.

Glass Protect recognizes glass break at a distance of up to 9 meters. Its
microphone should be positioned no more than 90 degrees relative to the
window(s).
Make sure that any curtains, plants, furniture, or other objects do not over
cover the microphone opening.
If there are curtains on the window, place the detector between them and
the window, for instance, at the window side jamb. Otherwise, curtains can
mute the glass break sound, and the detector will not be triggered.
Detector installation procedure
Before installing the detector, make sure that you have selected the optimal
location that follows the guidelines of this manual!
1. Fix the Smart Bracket attachment panel using bundled screws. If you use
any other attachment tools, make sure that they do not damage or deform
the attachment panel.
Use double-side adhesive tape only for temporary attachment of the detector. The tape runs dry
with time, which can cause falling, false triggering, and detector malfunction.
2. Put the detector on the attachment panel. When the detector is fixed in
Smart Bracket, it blinks with LED, signalling that the tamper is closed.
If LED doesn’t blink after fixing in Smart Bracket, check the status of the
tamper in the Ajax app and then the fixing tightness of the panel.
If someone detaches the detector from the surface or takes it off the
attachment panel, the security system notifies you.
Connecting a Wired Detector
A wired detector with an NC (normally closed) contact type can be
connected to Glass Protect using the in-built terminal clamp.

We recommend installing the wired detector at a distance no longer than 1
meter to Glass Protect. Longer wire length increases the risk of its damage
and reduces the quality of communication between the detectors.
To put out the wire from the detector body, break out the plug:
If the connected wired detector is triggered, you receive the notification.

Maintenance
Check the operational capability of the detector regularly.
Clean the detector body from dust, spider web, and other contaminants as
they appear. Use soft dry napkin suitable for tech equipment.
Do not use any substances containing alcohol, acetone, gasoline, and other active solvents to
clean the detector.
The pre-installed battery ensures up to 7 years of autonomous operation
(with the 5 minutes ping interval by the hub). If the detector battery is low,
the system notifies the user, and the LED indicator smoothly lights up and
goes off if a glass break is detected or the tamper is triggered.
As soon as the battery charge reaches a 10% level, the app reminds the
user to replace the battery.
