2.3 Step-by-step modernization

Building Technologies
Fire Safety
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.
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). 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These measures enable out-of-date fire detection installations to be gradually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 respective protocol of the installed
l
system:
– MS8/PMT
– Collective/GMT
– AnalogPLUS
– SIGMALOOP
– Interactive
No changes are required on the fire control panel.

Step 2: Replacing the existing fire control panel with a Sinteso
FC20xx control panel
At the same time, all peripheral devices that have not been modernized, such
l
as manual call points and input/output modules, must be replaced with devices
which can be used on the FDnet.
As an alternative to replacing the control panel, the existing line card in the fire
l
control panel can be replaced with a line card (FDnet).
