I/F for PWF 8000 LHD

Modbus Interface for Protectowire PWF-8000 Fibre-Optic LHD

SPIB

This Pertronic Modbus interface allows a Protectowire Fibre System 8000 fibre-optic linear heat detection system (LHD) to be integrated into a Pertronic F220 fire system.

The interface connects to the fire panel's RS-485 bus and communicates with the LHD via Modbus. It can be mounted inside the fire panel or at a remote location.

The interface uses the fire panel's loop emulation capability. Each zone on the LHD cable is mapped to a device on an emulated analogue addressable loop.

The Modbus connection is galvanically isolated from the fire alarm control panel’s RS-485 bus.

Features

  • Compatible with Pertronic F220 fire alarm control panels
  • Functions as Modbus master device
  • Modbus connection configurable RS-232 or RS-485, 300 bit/s to 115,200 bit/s
  • Supports Modbus TCP when connected to a Modbus Serial to Modbus TCP Gateway
  • Emulates up to four analogue addressable loops. (Note that the total number of actual and emulated loops cannot exceed the panel’s maximum loop capacity)
  • Supports up to 100 fibre-optic LHD detection zones per emulated loop (maximum 4 x 100)
  • Each zone on the LHD cable is mapped to a device on an emulated analogue addressable loop
  • Each emulated heat detector can report pre-alarm and fibre break as well as alarm signals
  • Optional fault supervision between the fibre-optic LHD interface and fire alarm control panel
  • Configurable with a PC running a terminal emulation program via USB mini-B cable
  • On-board LEDs provide diagnostic information
  • Electrically isolated from the fire alarm control panel’s RS-485 bus
  • Also compatible with F120A fire panels with v5.0 or later firmware
