FIBER OPTIC INTERFACE
INT-FI
int-fi_en 04/12
The INT-FI interface allows for conversion and transmission of data by means of optical
fibers. It is dedicated to interacting with the communication buses of INTEGRA alarm control
panels or the RS-485 bus of ACCO access control system. The interface enables the
maximum distance between the devices to be increased up to 4 km.
This manual refers to the INT-FI interface with firmware version 1.02.
Note: Interfaces with firmware version 1.02 are not compatible with those with earlier
versions of firmware. Keep this in mind and, if necessary, update the firmware in
interfaces with older firmware versions.
1. Features
Conversion of signals sent through the keypad / expander buses of INTEGRA alarm
control panel and the RS-485 bus of ACCO access control system.
4 connectors for two fiber pairs.
Terminals for connecting electric signals from three communication buses of INTEGRA
control panels (one keypad bus and two expander buses) or one RS-485 bus of ACCO
access control system.
Operation in different configurations, depending on jumper settings.
Test mode to enable checking the correctness of data transmission.
LEDs indicating the selected configuration.
Up to 2 km transmission distance between two fiber optic interface units.
A possibility to extend the fiber optic distance up to 4 km in case of daisy chain topology
(see Fig. 6).
Support for popular multimode fibers.
Updateable firmware.
Immunity of data transmission through optical fibers to electromagnetic interference.
Galvanic isolation of devices ensured.
