AJAX SYSTEMS AJ-S-GP-FIBRA-B, SUPERIOR GLASS PROTECT FIBRA BLACK

Superior GlassProtect Fibra is a wired glass break detector. Designed for indoor use. Supports connection of a third-party detector with a normally closed (NC) contact type.
Superior GlassProtect Fibra works as part of the Ajax security system, exchanging data with the hub using the secure Fibra wired protocol. The communication range is up to 2,000 m when connected via twisted pair U/UTP cat.5.
Superior GlassProtect Fibra is part of the wired Fibra devices line. The installation, sale, and configuration of these devices are performed only by accredited Ajax partners.

Operating principle
Superior GlassProtect Fibra is a wired glass break detector. It responds to glass breaking using a built-in electret microphone. The detectorʼs microphone using the DualTone digital algorithm only responds to sound vibrations characteristic of the sound of glass breaking, cutting off false alarms.
In the armed mode, the detector instantly transmits an alarm signal to the hub when it detects a break. The hub activates connected sirens, runs scenarios, and notifies users and the security company.
Users will know where a glass break has been detected. The notifications contain the name of the hub (name of the guarded facility), the name of the device, the type of alarm, and the virtual room to which the detector is assigned.

Protection from false alarms
The detector uses DualTone — a two-stage algorithm to exclude false alarms. To register a break, the detector must record a dull (low-frequency) sound of an impact and then a ringing (high-frequency) sound of falling fragments in 1.5 seconds. Owing to this algorithm, the detector does not respond to the barking of dogs or cars passing by the protected facility.

Fibra data transfer protocol
The detector uses Fibra technology to transmit alarms and events. This is a wired data transfer protocol to provide fast and reliable two-way communication between the hub and the connected devices. Using the bus connection method, Fibra delivers alarms and events instantly, even if 100 devices are connected to the system.
Fibra supports floating key block encryption and verifies each communication session with devices to prevent sabotage and spoofing. To monitor connection with the system devices and display their statuses in the Ajax apps, the protocol involves regular device polling by the hub with an interval of 12 to 300 seconds.

Connection of a third-party wired detector
A third-party wired detector with a normally closed (NC) contact type can be connected to Superior GlassProtect Fibra. This can be any detector: motion, opening, or vibration.
Superior GlassProtect Fibra will not power the third-party detector. The detector should be connected separately. To learn the type and input voltage of the third-party detector, refer to the device documentation or contact the manufacturerʼs technical support.

Sending events to the Central Monitoring Station (CMS)
The Ajax security system can transmit events and alarms to the PRO Desktop, monitoring app as well as the Central Monitoring Station (CMS) via SurGard (Contact ID), SIA DC-09 (ADM-CID), ADEMCO 685, and other proprietary protocols.

Superior GlassProtect Fibra can transmit the following events:

1. Glass break sensor alarm.
2. Alarm of connected third-party detector.
3. Tamper alarm/recovery.
4. Hub connection loss/restoration.
5. Activation/deactivation of the detector.
6. Unsuccessful attempt to arm the security system.

When an alarm is received, the operator of the security company monitoring station knows what happened and where to send the fast response team. Addressability of Ajax devices allows sending not only events but also the type of the device, the name, group, and virtual room assigned to it to the PRO Desktop and to the CMS. The list of transmitted parameters may differ depending on the type of the CMS and the selected communication protocol.
