GlassProtect User manual
Updated March 29, 2021
GlassProtect is a wireless indoor glass break detector recognizing the sound of shattering the
glass at a distance of up to 9 meters. GlassProtect can operate up to 7 years from a pre-
installed battery and has a socket for connecting a third-party wired detector.
GlassProtect connects to the Ajax security system via the protected radio protocol. The
communication range is up to 1,000 meters in line of sight. Also, GlassProtect can be connected
to third-party security systems using the or integration
modules.
Users can congure GlassProtect via the for macOS, Windows, iOS, or Android. The
system noties users of all events through push notications, SMS, and calls (if activated).
The user can connect the Ajax security system to the central monitoring station of a security
company.
Functional elements
Operating Principle
GlassProtect 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.
GlassProtect detector does not react to the breaking of the lm-covered glass: shockproof, sunscreen,
decorative, or any other type of lm. To detect the breaking of such kind of glass, we recommend using the
wireless opening detector with shock and tilt sensors.
If triggered, GlassProtect immediately transmits the alarm signal to the , activating the
(if connected) and notifying the user and security company.

Detector Connection to hub
Before starting connection:
Only users with administrator rights can add the device to the hub.
Pairing the detector with hub:
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 or
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 ping interval (the paragraph
on “Jeweller” settings in hub settings).
Detector functionality testing
Having dened the location of the detector and having xed the device with the bundled
adhesive tape, test the detection zone.
GlassProtect does not react to clapping!
Testing the detector
Hit the glass with your st 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 rst 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) rstly, 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 GlassProtect.
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 GlassProtect depends on its remoteness from the hub, and obstacles hindering
the radio signal transmission: walls, oors, large objects inside the room.
The device developed only for indoor use.

Attenuation Test
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 signicantly improve the quality of signal reception.
If the detector has low or unstable signal strength even after moving, use a
.
Do not install the detector:
GlassProtect 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 overcover 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!
If LED doesn’t blink after xing in SmartBracket, check the status of the tamper in the Ajax app
and then the xing tightness of the panel.
If someone detaches the detector from the surface or takes it off the attachment panel, the
security system noties you.
Connecting a Wired Detector
A wired detector with an NC (normally closed) contact type can be connected to GlassProtect
using the in-built terminal clamp.
We recommend installing the wired detector at a distance no longer than 1 meter to
GlassProtect. 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 notication.
ReX radio signal
range extender
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.
1. Fix the SmartBracket 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 xed in SmartBracket, it
blinks with LED, signaling that the tamper is closed.
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 noties the user, and the LED
indicator smoothly lights up and goes off if a glass break is detected or the tamper is triggered.
