The BACnet Gateway facilitates communication between a Pertronic F120 fire alarm panel and a Building Management System (BMS). The gateway monitors data broadcast by the fire alarm panel and reports specific items to the BMS using the BACnet protocol. Options in the configuration software allow the gateway to be configured to create BACnet objects representing a wide range of data items from the fire alarm panel. The gateway system consists of a Contemporary Controls BASGatewayLX Gateway Module connected to a Pertronic Industries GPIB-M Modbus Interface. The system is normally installed inside the fire alarm cabinet. It connects to the BMS physical network via an Ethernet port.
