Satel Int-Fi Fibre Optic Interface

The INT-FI converter is used to convert and transmit data via fiber optic cables. It provides high communication immunity to potential interference with complete galvanic separation of the connected devices. It is designed to work with the keypad and expander communication buses of INTEGRA series control panels, as well as with the RS-485 bus of the ACCO access control system. The INT-FI is equipped with four sockets to connect two pairs of optical fibers, as well as terminals to connect signals from three communication buses of INTEGRA control panels (one keypad bus and two expander buses) or one RS-485 bus of the ACCO access control system.

Depending on the settings of jumpers on the PCB, the INT-FI can work in a variety of configurations, with the selected one being indicated by LEDs. Using the appropriate type of network connection (cascade) enables the transmission range to be increased by up to 4 km, with the maximum distance between the two converters being 2 km.
