AJAX GlassProtect Wireless Indoor Glass Break Detector

GlassProtect is a wireless indoor glass break detectorthat  recognizes the sound of shattering the glass at a distance of up to 9 meters. GlassProtect can operatefor  up to 7 years from a preinstalled battery and has a socket for connecting a third-party wired detector.
GlassProtect 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, GlassProtect can be connected to third-party security systems using the Ajax UART bridge or Ajax Oxbridge Plus, integration modules.
Users can configure GlassProtect via the Ajax app for macOS, Windows, iOS, or Android. The system notifies users of all events through push notifications, SMS, and calls (if ctivated).
The user can connect the Ajax security system to the central monitoring station of a security company.

Operating Principle

GlassProtect uses a sensitive electret microphone to detect the sound of glass breaking, consisting of a low-frequency hit sound and a high-frequency crashing sound of glass shatters. Such two-stage glass break detection decreases the risk of false triggering.
warning GlassProtect detector does not react to the breaking of the lm-covered glass: shockproof, sunscreen, decorative, or any other type of film. To detect the breaking of such kind of glass, we recommend using the DoorProtect Plus wireless opening detector with shock and tilt sensors.
If triggered, GlassProtect immediately transmits the alarm signal to the hub, activating the sirens (if connected) and notifying the user and security company.

Connecting

Detector Connection tothe  hub
Before startingthe  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.

warning 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.

  4. Switch on the device.

AJAX GlassProtect Wireless Indoor Glass Break Detector - fig2

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 uarbridge or Oxbridge 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 starts depending on the settings of the detector ping interval (the paragraph on “Jeweller” settings in hub settings).

Having denied the location of the detector and having xed the device with the bundled adhesive tape, test the detection zone.

RAZER RZ03 03390500 R3U1 Huntsman Mini Gaming Keyboard - Symbol 17 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 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.
RAZER RZ03 03390500 R3U1 Huntsman Mini Gaming Keyboard - Symbol 17 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 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
warningIn 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, doors, and large objects inside the room.
warningThe device was developed only for indoor use.
warningCheck 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.

GlassProtect recognizes glass breaks 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!

  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.
    RAZER RZ03 03390500 R3U1 Huntsman Mini Gaming Keyboard - Symbol 17 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 SmartBracket, it blinks with LED, signaling that the tamper is closed.

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 notices 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.

AJAX GlassProtect Wireless Indoor Glass Break Detector - fig3

We recommend installing the wired detector at a distance of 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:

AJAX GlassProtect Wireless Indoor Glass Break Detector - fig4

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 a soft dry napkin suitable for tech equipment.
warningDo 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 notices the user, and the LED indicator smoothly lights up and goes off if a glass break is detected or the tamper is triggered.
