The Pertronic SPIB Modbus Interface (SPIB-MODBUS HLI) allows bi-directional communication between a Pertronic F220 or F120A fire alarm control panel and one or more Modbus master devices such as a Building Management System (BMS).
The interface monitors the fire alarm control panel’s RS-485 bus and stores a copy of the panel’s current event queue data in a Modbus-compatible format. This includes all major events that would be shown on the fire alarm control panel’s LCD display.
External devices are able to communicate with the fire alarm system via the Modbus interface using the F220’s loop emulation capability. The interface translates data from external Modbus registers into detector or module status data readable by the fire alarm control panel. The interface can emulate up to four analogue addressable loops. The Modbus Interface can also transfer isolate & de-isolate requests to the control panel.
The Modbus Interface supports ASCII and RTU Modbus modes over either RS-232 or RS-485. When fitted with a Modbus Serial to Modbus TCP Gateway such as the MOXA MB3180, it also supports Modbus TCP.
When used with a suitable Modbus master device, the Modbus interface can optimise communication speed by packing data from up to four devices into a single Modbus register.
Pertronic also manufactures a Modbus interface for connecting F220/Net2 Network Systems directly to building management systems. Please refer to the Net2 Network System Datasheet for more information.
