Description
The 2010-1-NB RS485 FireNet network board allows for the creation of a bus mode class-B, or redundant class-A, 32 node network, supporting up to 64 zones. Each node may be a fire panel or a fire panel repeater. When optical fibre is preferred, when cable lengths above 1200 m between nodes are required, or in cases where high levels of EMC are expected, a standard RS485 to fibre converter may be used. The 2010-1-NB is connected directly to the main board of the panel. No cabling needs to be done between the network board and the main board. Networking makes it possible to repeat the user interface of any panel as required. There could be various reasons for using a network e.g. If there are multiple exit doors in a building and at each exit door the status of the fire system is required. Where the load of the system needs to be spread to safeguard against failure of a single panel. To minimise cabling and installation costs. For larger installations where multiple panels are required but yet central control is required at a single location. Networking is also useful when an existing system needs to be expanded. Instead of replacing a perfectly good panel with a larger one, simply install and additional panel and connect them together in a network. This makes it ideal for cost effective, future expansion.
