Fibra power supply calculator


This calculator is designed to check the security system project.

To get correct results, you need:

  1. The list of Fibra devices.
  2. Cable type and the resistance value for each Fibra line (bus).
  3. Exact cable lengths between Fibra devices, considering cable routing.

This calculator is a behavior pattern of a wired Ajax security system. It does not take into account the cable quality, connection to terminals, type of cable connection, and other parameters depending on the installer. Therefore, the calculated results may differ from the actual values in the Ajax apps.

The calculator estimates the power consumption of Fibra devices having the latest firmware versions. After installation, we recommend that you run the power supply test in the Ajax app.
