INT-FI - bus to fiber optic converter for INTEGRA control panels and ACCO system
INT-FI is a converter for converting and transmitting data via fiber optic cables in alarm systems SATEL. The device provides high resistance of communication to interference and full galvanic separation of connected devices.
- Conversion of INTEGRA control panel communication buses to fiber optic pair transmission
- Supports two pairs of fiber optic cables to allow multiple modules to be daisy-chained together
- Permissible distance between two converters up to 2 km
- Cooperation with popular multimode optical fibers
- Full galvanic separation of devices and high resistance to interference
Application of INT-FI converter
INT-FI converter is designed for cooperation with communication buses of keypads or expanders of INTEGRA series alarm control panels, as well as with RS-485 bus of ACCO access control system. It enables the implementation of data transmission via fiber optic cables in places where long distances between devices and increased resistance to electromagnetic interference are required.
By using the appropriate type of network connection in the form of a cascade, it is possible to increase the transmission range up to 4 km, while maintaining a maximum distance of 2 km between two neighboring converters. This solution works well in extensive facilities where numerous keypads, expanders or access control system components are used.
Design and operation of the module
INT-FI is equipped with four sockets for connecting two pairs of fiber optic cables and terminals for connecting signals from three communication buses of INTEGRA control panels (one keypad bus and two expander buses) or one RS-485 bus of the ACCO system. Configuration of the converter's operation mode is carried out using jumpers on the electronics board.
Selected operating configurations are indicated by LEDs, which makes it easier for the installer to control the settings and diagnose the module's operation. The use of popular multimode optical fibers simplifies the choice of cabling and integration with the existing infrastructure in the facility.
Resistance to interference and transmission security
The use of fiber-optic transmission ensures high resistance of communication to potential electromagnetic interference, surges and differentnice potentials between different parts of the installation. INT-FI guarantees full galvanic separation of connected devices, which is particularly important for extensive security systems in industrial, office and public facilities.
Maintaining proper environmental and power supply parameters in accordance with the manufacturer's specifications allows the INT-FI module to operate stably and without failure in environmental class II. As a result, the device can be installed in typical indoor conditions, according to the requirements of alarm systems SATEL.
