📘 GlassProtect User manual

GlassProtect is a wireless detector detecting glass break at a distance up to 9 meters. It is used inside premises, can operate up to 7 years from a factory-assembled battery and is furnished with a socket for connecting an additional detector.

DoorProtect operates within the Ajax security system, by connecting via the protected Jeweller protocol to the Hub. Communication range - up to 1,000 m, absent any obstacles. In addition, the detector can be used as part of third-party security central units due to the uartBridge or ocBridge Plus integration module.

The detector is set up via a mobile application for iOS and Android-based smartphones. The user is notified of all events through push notifications, SMS messages and calls (if activated).

The Ajax security system is self-sustaining, but the user can connect it to the central monitoring station of a private security company.

GlassProtect Operating Principle

GlassProtect is furnished with a sensitive electret microphone and set up to detect the distinctive sound of broken glass, consisting of a low-frequency hit and high-frequency tinkle of chips. Due to the two-stage glass break detection, the risk of false actuation is minimal.

After actuation, the GlassProtect detector set in the intrusion detection mode immediately transmits an alarm signal to the Hub, activating the sirens connected to the Hub and notifying the user and private security company.

Connecting the Detector to the Ajax Security System

Detector Connection to Hub

Before starting connection:

  • Following the Hub instruction recommendations, install the Ajax application on your smartphone. Create an account, add the Hub to the application, and create at least one room.
  • Go to the Ajax application.
  • Switch on the Hub and check the internet connection (via Ethernet cable and/or GSM network).
  • Ensure that the Hub is in armed mode and does not start updates by checking its status in the mobile application.

⚠️ Only users with administrative privileges can add the device to the hub.

How to connect the detector to the Hub:

  1. Select the Add Device option in the Ajax application.
  2. Name the device, scan/write manually the QR Code (located on the body and packaging), and select the location room.

  3. Select Add — the countdown will begin.
  4. Switch on the device

For the detection and interfacing to occur, the detector should be located within the coverage area of the wireless network of the hub (at a single protected object).

Request for connection to the hub is transmitted for a short time at the time of switching on the device.

If the connection to the Ajax Hub failed (LED blinks once per second), switch off the detector for 5 seconds and repeat the attempt. The detector connected to the hub will appear in the list of devices of the hub in the application. Update of the detector statuses in the list depends on the device inquiry time set in the hub settings, with the default value - 36 seconds.

Connecting the Detector to Third Party Security Systems

To connect the detector to a third party security central unit using the Ajax uartBridge or Ajax ocBridge Plus integration module, follow the recommendations in the manual of the respective device.

Performance testing

The Ajax security system allows conducting tests for checking the functionality of connected devices.

The tests do not start straight away but within a period of 36 seconds when using the standard settings. The test time start depends on the settings of the detector scanning period (the paragraph on “Jeweller” settings in Hub settings).

  • Signal Strength Test
  • Detection Area Test
  • Signal Fade Test

Having defined the location of the detector and having fixed the device with a prepackaged adhesive tape, test the detection zone.

The GlassProtect detector is not sensitive to any pops! 

How to test the sensor

Hit hard on the glass by your fist without breaking it! If the detector microphone catches a low-frequency sound, the LED will blink. Simulate a high-frequency glass break sound during 1.5 seconds after the first hit - by a special instrument or by hitting on a glass with a metal object. After reading out the sound, the detector will extinguish the LED for a second. 

While in the intrusion detection mode, to be actuated, the detector needs to catch sounds in the following sequence: low-frequency sound (hit), then high-frequency sound (glass break, chips). Otherwise, the alarm will not be actuated. 

Switch on/off all the equipment usually operating within the room: generators, air conditioning units, etc. If the detector is actuated, it means that too high sensitivity is set or the location of the GlassProtect needs to be changed. 

Use the sensitivity level, at which the detector properly passes both test stages and does not respond to any equipment operating within the room.

After setting the system in the intrusion detection mode, conduct a checkup operational test of the GlassProtect.

Installing the device

Selecting an installation location

In some cases, the household activity can cause false alarms.

Location of the GlassProtect detector determines its remoteness from the hub and presence of any obstacles between the devices hindering the radio signal transmission: walls, inserted floors, large-size objects located within the room.

Check the signal level at the installation location

If the signal level is one division, we cannot guarantee stable operation of the security system. Take possible measures to improve the quality of the signal!

Do not install the detector:

  • outside the premises (outdoors)
  • nearby sirens and annunciators
  • nearby any metal objects or mirrors causing attenuation and screening of the signal
  • at any places with fast air circulation (air fans, open windows or doors)
  • within any premises with the temperature and humidity beyond the range of permissible limits

The GlassProtect detector detects glass break at a distance up to 9 meters. Its microphone should be positioned at the angle 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 the window is covered by thick curtains, place the detector between them and the window. For example, at the window jamb. Otherwise, the curtains may drown glass break sound and the detector will not be actuated.

The installing of the sensor

Before installing the detector, make sure that you have selected the optimal location and it is in compliance with the guidelines contained in this manual!

  1. Fix the SmartBracket attachment panel of the detector using factory-made screws. If using any other attachment hardware, make sure that they do not damage or deform the panel.
    The double-sided adhesive tape may be only used for temporary attachment of the detector. The tape will run dry in course of time, which may result in falling of DoorProtect and actuation of the security system. Furthermore, the device may fail from a hit.
  2. Put the detector on the attachment panel. As soon as the detector is fixed in SmartBracket, it will blink with a LED - this will be a signal that the tamper on the detector is closed.
    If the light indicator of the detector is not actuated after installation in SmartBracket, check the status of the tamper in the Ajax Security System application and then the fixing tightness of the panel.
  3. If the detector is torn off from the surface or removed from the attachment panel, you will receive the notification.

Connecting a Wire Detector

A wire detector with an NC type contact may be connected to the GlassProtect using an outside-mounted terminal clamp.


We recommend to install the wire detector at a distance not exceeding 1 meter - increasing the wire length will increase the risk of its damage and reduce the quality of communication between the detectors.

To lead out the wire from the detector body, break out the plug:

If the external detector is actuated, you will receive the notification.

Detector Maintenance and Battery Replacement

Check the operational capability of the GlassProtect detector on a regular basis.

Clean the detector body from dust, spider web and other contaminations as they appear. Use soft dry napkin suitable for equipment maintenance. 

Do not use for cleaning the detector any substances containing alcohol, acetone, gasoline and other active solvents.

The battery installed in the detector ensures up to 7 years of autonomous operation (with the inquiry frequency by the hub of 5 minutes). If the detector battery is discharged, the user will receive a notice, and the LED will smoothly light up and go down if the detector or tamper is actuated.
