Fire alarm system F220-Net2

Overview
The Pertronic F220-Net2 network links multiple F220 fire panels, Net2 Network Control Units (Net2 NCU) and Net2 remote displays into a single fault-tolerant fire alarm network. It prioritises alarm and control traffic to ensure rapid delivery under high network load.

On a Pertronic F220-Net2 Network

• Any connected fire panel can be controlled and monitored from any Net2 NCU
• Information from any panel can be viewed on any Net2 NCU or Net2 remote display
• Events anywhere on the network can trigger or influence events on any connected fire panel

Network composition
An F220-Net2 network supports up to 133 Net2 Network Cards (nodes). Each node may interface one of the following to the network:

• One F220 fire panel (FP) and/or multiple Net2 NCUs or Net2 remote displays
• Modbus master device
• Pertronic FireMap® workstation
• ASCII text-based systems including printer or pager

A single network card may connect up to eight Net2 NCUs or Net2 remote displays and up to eight LED display/output controllers. Each NCU can provide full control and monitoring of any or all networked panels.

Features

• Up to 100,000 panel-to-panel object mappings per system
• Up to 5,000 object mappings to any individual fire panel
• 640 configurable network inputs per panel (multiple objects may be mapped per input)
• 359 logical inputs per panel
• Zone numbers supported from 0 to 64,999
• Plain-text descriptors for network inputs, NMOs, NCUs and remote displays (mini-mimics)
• Plug-in fibre-optic modules allow a mix of RS-485 twisted-pair copper and fibre-optic segments
• Bi-directional Modbus interface providing:
  
  • 3,000 Boolean Nodal Mapping Objects (NMOs)
  • Ability to map up to 8 timers from any panels to Modbus registers
  • Mappable I/O watchdog
• Ring topology ensures a single cable fault does not interrupt network operation
• Automatic fault supervision detects earth faults on copper segments, circuit breaks and node/configuration changes
• Programmable via Pertronic FireUtils® over a password-protected Ethernet connection
• Typical upload times: 34 nodes < 1 minute; 130 nodes < 5 minutes
• Automatic system-wide clock synchronisation and daylight saving adjustment
• System time adjustable from any fire panel
• Loop devices testable from any Net2 NCU
• Users can reset or disable individual loop devices, alarm routing, timers, logic blocks and network inputs from any Net2 NCU
• Recent Network Event log and panel data logs (including history) accessible from NCUs, panels and full-function mimics
• Panel data logs downloadable to FireUtils® from any node
• NET2CARD Linux OS diagnostic logs available for Pertronic technical support analysis
• 133-node F220-Net2 network certified to AS 7240.13:2006 by an IANZ-accredited laboratory
• Activfire listed (afp-3054) to AS 7240.13:2006
