How GlassProtect works

GlassProtect is equipped with a highly sensitive electronic microphone, designed to distinguish the distinctive sounds of breaking glass, including the low-frequency impact sound and the high-frequency tinkling sound of cracking glass. Thanks to its two-stage glass break detection mechanism, the risk of false alarms is minimized.

⚠️ The GlassProtect device will not react to breakage if a film has been applied to the glass: shockproof, sunproof, decorative, or other. To detect breakage of this type of glass, we recommend using the DoorProtect Plus wireless open detector with shock and tilt sensors.

Once activated, GlassProtect, in intrusion detection mode, will immediately transmit an alarm signal to the Hub, triggering the siren connected to the Hub and notifying the user and the security company.

Connect the device to the Ajax security system.

Connect the sensor to the hub.

Before starting the connection:

1. Install the Ajax app on your phone and follow the instructions to set up the Hub (Hub, Hub Plus).

2. Create a user account, add the Hub to the app, and create at least one room.

3. Open the Ajax application.

4. Turn on the hub and check your internet connection.

5. Check and make sure that the Hub is in the Disabled mode and not updating (check the status displayed in the application).

⚠️ Only users with administrator privileges can add new devices to the Hub.

How to connect a device to the Hub:

1. Select “Add device” in the Ajax app.

2. Name the motion sensor device, scan the QR code or manually enter the device's code into the app (the code is located under the lid and on the box), and select the Room for the device.

3. Select “Add” - the countdown will begin.

4. Turn the device's power button to "On".

For the device to operate effectively and without interference, the sensor must be placed within the wireless coverage area of ​​the Hub (with a protective object).

A request to connect to the Hub will be sent shortly after the device is powered on. If you are unable to connect to the Hub, try turning the device off and on again after 5 seconds.

Once connected, the sensor device will appear in the list of connected devices. The frequency of signal scanning will depend on the settings on the Hub, with a default of 36 seconds.

Connect the sensor device to third-party security systems.

To connect the sensor to third-party central processors, you can use the integrated Ajax uartBridge or Ajax ocBridge Plus module, following the instructions in the product manual.

Check the sensor device.

The Ajax security system allows for testing to assess the functionality of connected devices.

The testing modes will not start immediately but after a 36-second cycle when using the default settings. The start time of the test depends on the sensor's scan cycle settings (see the "Jeweller" settings in the Hub's settings).

• Check signal strength

• Check the scan range.

• Check for decline

After locating the detector and securing it with the included tape, test the detection area.

GlassProtect detectors are not sensitive to any explosions!

Check the glass break sensor.

Hit the glass hard with your fist without breaking it! If the detector microphone picks up a low-frequency sound, the LED will flash. Simulate a high-frequency glass-breaking sound for 1.5 seconds after the first hit – using a special musical instrument or by touching the glass with a metal object. After reading the sound, the detector will turn off the LED for one second.

To detect broken glass in activated mode, the sensor must pick up sounds in the following frequency order: low frequency (impact) followed by high frequency (glass breaking, cracking). Otherwise, the alarm will not be triggered.

Turn all normally operating devices in the room on/off: generator, air conditioner, etc. If a device is activated, it means the sensitivity is too high or the position of GlassProtect needs to be changed.

Use the sensitivity level at which the detector passes both phases of the test and does not react to any operating equipment in the room.

After setting the system to the active mode, proceed to test the functionality of GlassProtect.

Equipment installation

Choose the installation location.

In some cases, household activities can often trigger false alarms.

The optimal placement for GlassProtect depends on the distance between the device and the central hub, as well as the number of obstacles in between that can degrade signal quality: walls, floors, and large objects in the room.

⚠️ Check the signal strength in the settings.

If the signal strength is only one bar, Ajax won't guarantee that the system will work perfectly. Do everything you can to improve the signal quality! At the very least, try moving the device; even just 20 cm can significantly improve the connection quality.

If, after moving, the device still has a weak or unstable signal, use a ReX signal booster.

Do not install the device at:

• Outdoor area

• Keep away from metal objects or glass surfaces as this may affect the quality of the connection signal.

• In areas where the temperature and humidity range of the device is exceeded.

• In areas with strong airflow (fans, windows or doors open at all times)

• Near alarms or other sources of sound.

GlassProtect can detect glass breakage from a distance of up to 9 meters. Its microphone must be positioned at an angle of no more than 90 degrees to the glass surface to be protected.

Make sure there are no obstructions in front of the device's microphone hole.

If the window is covered by thick curtains, place the detector between them and the window. For example, at the edge of the window frame. Otherwise, the curtains may drown out the sound of breaking glass and the detector will not be triggered.

Sensor installation guide

Before installation, make sure you have chosen a location that meets the requirements of this instruction manual.

1. Attach the smart wall panel to the surface using screws, employing at least two fixing points (one of which should be above the vandal-proof section). After selecting other mounting hardware, ensure that it does not damage or deform the wall panel.

Double-sided tape should only be used as a temporary fixation solution for equipment. The tape will dry out over time and could cause the equipment to fall, leading to malfunction or potentially damaging the equipment due to the fall.

2. Place the device on the mounting bracket. As soon as the device is secured on the SmartBracket, its LED will flash – this signals that the device's tamper-proof cover is closed. If the device's LED indicator does not light up after installation on the SmartBracket, check the tamper-proof status in the Ajax Security System app and adjust the tightness of the mounting bracket.

3. If the device is pulled away from the mounting surface or detached from the mounting bracket, you will receive a notification.

Connect to a wired sensor device.

A wired sensor with an NC connector can be linked to the GlassProtect device via the external port slot.

Ajax recommends that you install wired devices at a distance of no more than 1 meter – the greater the distance between the wires, the higher the risk of damage and reduced signal quality between devices.

To pull the cord out of the device, bend open the socket:

If an external sensor is linked, you will receive a notification.

Equipment maintenance and battery replacement.

You should regularly check the functionality of the Ajax security system.

Clean the machine body of dust, cobwebs, or other dirt. Use only a soft, dry cloth for maintenance.

Do not use cleaning agents containing alcohol, acetone, or gasoline to clean the equipment.

The built-in battery ensures automatic operation for up to 7 years (with the central hub querying every 5 minutes).

If a low battery is detected, the security system will send corresponding notifications, and the LED will light up and turn off if the detector detects any movement or if the tamperer is activated.

When the battery level reaches 10%, the system will immediately notify you that the battery needs replacing.
