GlassProtect User Manual

Updated December 4, 2023

GlassProtect is a wireless indoor glass break detector that detects the sound of glass breaking up to 9 meters away. Indoor use. GlassProtect can operate for up to 7 years on a pre-installed battery and has a socket for connecting a third-party wired detector.

GlassProtect connects to the Ajax system using the protected Jeweller wireless protocol. The communication range is up to 1,000 meters in line of sight. In addition, GlassProtect can be connected to third-party security systems using the uartBridge or ocBridge Plus integration modules.

Users can configure GlassProtect via the Ajax application for macOS, Windows, iOS or Android. The system notifies users of all events through push notifications, SMS and calls (if enabled).

The user can connect the Ajax system to the central monitoring station of a security service.

GlassProtect uses a sensitive electret microphone to detect the glass breakage sound, which consists of a low-frequency impact sound and a high-frequency breakage sound of broken glass. Such two-stage glass breakage detection reduces the risk of false alarms.

The GlassProtect detector does not react to the breaking of the film-covered glass: shockproof, solar protection, decorative or any other type of film. To detect the breakage of such types of glass, we recommend using the wireless DoorProtect Plus opening detector with impact and tilt sensors.

If the alarm is triggered, GlassProtect immediately transmits the alarm signal to the hub , activates the sirens (if connected) and notifies the user and the security service.

Connection

Detector connection to the hub

Before establishing the connection:

Follow the Hub user manual and install the Ajax app , create the account, add the Hub and create at least one room.
Turn on the hub and check the Internet connection (via Ethernet cable and/or GSM network).
Make sure the hub is disabled and not updating by checking the status in the Ajax app.

Only a user with administrator rights can add the device to the hub.

Coupling the detector with the hub:

Select Add device in the Ajax app.
Name the device, scan or enter the QR code (located on the detector housing and packaging) and select the installation room.
Tap Add — the countdown begins.
Turn on the device.

For detection and connection to occur, the detector must be within the range of the hub's wireless network (at a single protected facility). The connection request is transmitted for a short time when the device is turned on.

If the device failed to pair (LED flashes once per second), turn it off for 5 seconds and try again. The detector connected to the hub will appear in the list of devices in the app. The update of detector statuses in the list depends on the device ping interval set in the hub settings (the default is 36 seconds).

Connection 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.

Setting the doorbell

The doorbell is a sound signal that indicates the activation of the opening detectors when the system is disarmed. The function is used, for example, in shops to notify employees when someone has entered the building.

The configuration of these messages takes place in two steps: setting up opening detectors and setting up sirens.

Functional test

The Ajax system allows you to conduct tests to check the functionality of connected devices.

The tests do not start immediately, but within a period of 36 seconds when using the default settings. The start of the test time depends on the settings of the detector ping interval sampling period (the section on the "Jeweller" settings in the hub settings).

Jeweller Signal Strength Test

Detection range test

Damping test

Testing the detector functionality

After determining the position of the detector and securing the device with the supplied adhesive tape, test the detection area.

GlassProtect does not respond to clapping!

Testing the detector

Hit the glass with your fist without breaking it. When the detector detects a low frequency sound, the LED will flash. Simulate a high frequency glass breaking sound for 1.5 seconds after the first hit with a special tool or after hitting glass with a metal object. After detecting the sound, the detector will turn off the LED indicator for one second.

To be triggered when the system is armed, the detector must detect sounds in the following order: first the low-frequency sound (hit), then the high-frequency sound (broken glass, broken glass). Otherwise, the alarm will not be triggered.

Turn on/off all devices that normally work in the room: generators, air conditioners, etc. If this triggers the detector, try changing the sensitivity or relocating GlassProtect.

Use the sensitivity level at which the detector passes both test stages correctly and does not react to devices operating in the room.

Installing the device

Selecting the location

In some cases, activities in the house can cause false alarms

The location of GlassProtect depends on the distance from the hub and obstacles that hinder the transmission of the radio signal: walls, floors, large objects in the room.

Device is intended for indoor installation only.

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 signal quality. At least move the detector. Even a shift of 20 cm can significantly improve the quality of signal reception.

If the device has a weak or unstable signal strength at the other location, use a signal-boosting wireless repeater .

Do not install the detector as follows:

outside the premises (outdoors);
near sirens and loudspeakers;
near metal objects or mirrors that cause attenuation or shielding of the signal;
in all places with rapid air circulation (air fans, open windows or doors);
in rooms where the temperature and humidity are outside the permissible range;
closer than 1 m from the hub.

GlassProtect detects broken glass at a distance of up to 9 meters. The microphone should not be positioned more than 90 degrees relative to the window(s).

Make sure that curtains, plants, furniture or other objects do not block the microphone opening.

If there are curtains on the window, place the detector between the curtains and the window, for example on the window frame. Otherwise, curtains may muffle the sound of glass breaking and the detector will not be triggered.

Detector installation procedure

Before installing the detector, make sure that you have chosen the optimal location that complies with the guidelines in this manual!

Attach the SmartBracket mounting plate using the screws provided. If you use other fastening tools, make sure they do not damage or deform the mounting plate.

Use only double-sided tape to temporarily attach the detector. The tape will wear out over time, which may result in the detector falling off, false activation, and malfunction.
Place the detector on the mounting plate. When the detector is mounted in SmartBracket, it will flash an LED to indicate that the tamper protection is closed.

If the LED does not blink after fixing in SmartBracket, check the status of the manipulation in the Ajax app and then the fixation tightness of the plate.

If someone detaches the detector from the surface or removes it from the mounting plate, the security system will notify you.

Connecting a wired detector

A wired detector with an opener contact (breaker) can be connected to GlassProtect via the built-in connection terminal.

We recommend installing the wired detector at a distance of no more than 1 meter from GlassProtect. Longer wire lengths increase the risk of damage and reduce the quality of communication between the detectors.

To lead the wire out of the detector housing, break out the connector:

When the connected wired detector is triggered, you will receive the notification.

maintenance

Check the functionality of the detector regularly.

Clean the detector housing from dust, cobwebs and other contaminants. Use a soft, dry napkin suitable for technical devices.

Do not use substances containing alcohol, acetone, gasoline, or other active solvents to clean the alarm control panel.

The pre-installed battery ensures autonomous operation for up to 7 years (with the 5-minute ping interval by the hub). When the detector battery is low, the system notifies the user, and the LED indicator lights up gently and goes out when a glass break is detected or the tamper protection is triggered.
