  • What should you do if a detector or a device loses communication with the Hub

    A device may lose communication with the Hub for the following reasons: Low radio signal strength. Obstacles along the radio signal path. High noise level in the radio channel. Device malfunction. Wha...

  • What is a tamper

    Tamper is a miniature button on the device board. It is released when the lid is opened as well as a result of an attempt to unfasten and/or lift the device from the surface, which initiates an event....

  • Detection Zone Test

    Devices → [DEVICE] → Settings → Detection Zone Test → Start The detection area tests allow you to determine the distance at which the detector will detect alarms and protect it from false triggering. ...

  • Attenuation Test

    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 set...

  • Signal Strength Test

    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 set...

  • I’ve installed several detectors in one room, but they all show different temperatures.

    Each device measures temperature independently with an internal sensor. Air circulation in a room, along with other factors, may cause slight inconsistencies in the measured temperatures. The temperat...

  • How do I add the detector to the system? I can’t find the QR-code.

    The QR-code is located next to the power button, under the cover on the rear side of the detector. You can also find the QR-code on the box the device came in....

  • How long will it take ocBridge Plus to detect a communication failure with a detector?

    By default, ocBridge Plus response period is set to ping detectors every 36 seconds and to signal an alert after 40 undelivered passes. Under these settings, it will take about 24 minutes for the syst...

  • How to avoid false alarms of Motion sensors?

    When selecting the device installation location, take into account the lens direction and presence of any obstacles impairing the view and radio signal transmission. The detector should be attached to...
