Step-by-step modernization
Step-by-step modernization involves firstly replacing the existing detectors with
ones which support both the current detector protocol – hereinafter referred to as
the alternative protocol – and the FDnet-Ex/C-NET-Ex.
The replaced detectors initially continue to be operated with the alternative
protocol.
If the fire control panel is replaced at the end of the modernization project, the point
detectors automatically change over to the new protocol (FDnet-Ex/C-NET-Ex).
The existing cabling can usually be transferred with ease.
These measures enable out-of-date fire detection installations to be gradually
replaced with modern, sensitive fire detection installations with false alarm
immunity.
This document does not cover modernization via the control panel with a line card
of an alternative protocol, e.g. collective.
Step 1: Replacing the existing point detectors with
multiple protocol detectors
The detectors communicate with the protocol of the installed system
(collective Ex).
No changes are required on the fire control panel.
Step 2: Replacing the existing fire control panel with a control panel
Sinteso FC20xx or Cerberus PRO FC72x
At the same time, all peripheral devices that have not been modernized, such
as manual call points and input/output modules, must be replaced with devices
which can be used on the FDnet-Ex/C-NET-Ex.
As an alternative to replacing the control panel, the existing line card in the fire
control panel can be replaced with a line card (FDnet/C-NET).
