LineSupply (75 W) Fibra

Module for additional power supply with 75 W power and two output Fibra lines



Fibra communication technology

Proprietary wired communication technology combines the reliability of wires with the freedom of radio connection.
Key features:
  • Two-way communication.
  • Advanced anti-sabotage.
  • Block encryption featuring a dynamic key.
  • Instant notifications.
  • Remote configuration in the Ajax apps.

Line connection

4-core cable


to any point of the Fibra line
LineSupply (75 W) can be installed after a hub, detector, keypad, siren, or another LineSupply. The module provides additional power to Fibra devices installed between the LineSupply (75 W) and the end of the line.

Wired connection range

  • between the module and the hub — up to 6,500 ft ;
  • between the module and the last Fibra device on each line — up to 6,500 ft .
The maximum line length is relevant when using the U/UTP cat.5 twisted pair.

Encrypted communication

All stored and transmitted data are protected by block encryption featuring a dynamic key.

Line connection

Number of input lines

LineSupply (75 W) can be connected after any Fibra device.

Number of output lines

Fibra devices with a total power consumption of up to 30 W can be connected to the output line. LineSupply (45 W) Fibra version is also available, featuring less output power and one output line instead of two.

Cable length

up to 6,500 ft
For each output line between the module and the last Fibra device on the line when using U/UTP cat.5 twisted pair.

Galvanic isolation

Ensures that devices connected between the LineSupply (75 W) and the end of the line do not consume power from the hub.
