Transmitter Fibra

Fibra communication technology

Proprietary wired communication technology. Fibra 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

Connection

to any point of the Fibra line

Transmitter Fibra can be installed after a hub, detector, keypad, or siren.

Fibra line length

up to 6,500 ft

When using the U/UTP cat.5 twisted pair cable.

Encrypted communication

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

Supported configurations

• roller shutter
• tamper
• wired device with 15 event types

Connector pins

• 12V — power supply output for a wired detector
• GND — ground
• Z1–Z2 — inputs for connecting a wired detector
• COM — common input for connecting signal contacts of a wired detector

Transmitter Fibra has 2 inputs (Z1 and Z2) to connect the wired detector using the AATT (i.e., Alarm Alarm Tamper Tamper) scheme.

Type of connection

NO, NC, EOL, 2EOL, 3EOL

With EOL total resistance from 1 kΩ to 40 kΩ with a 100 Ω increment.

Cable length

up to 3 m

When using a signal cable with a 0.22 mm² copper conductor.

Operation mode

pulse, bistable

Event types

15 event types of wired devices

• Tamper alarm
• Intrusion
• Fire
• Auxiliary alarm
• Panic button
• Gas alarm
• Malfunction
• Leakage
• Glass break
• High temperature
• Low temperature
• Masking
• Duress code (opening)
• Vibration (seismic sensor)
• Custom

Adjusted by a PRO or a user with admin rights in the Ajax app.

Protection against spoofing

device authentication

Instant line damage detection

Valid for EOL, 2EOL, or 3EOL connections.

Communication loss detection

after 36 s

Between the hub and Transmitter Fibra. It can be changed in the hub settings.

Fibra line

7–30 V⎓, up to 200 mA

The hub powers the module.

Output to the connected wired device

10.5–15 V⎓, up to 50 mA (total maximum current consumption)

One power supply line from Transmitter Fibra.
