Undertaking modernization 

4.1

 

Step 1: Detector modernization 

The following steps must be taken during each modernization: 
1.  For information about installing new detector bases FDB20x or FDB22x, see 

chapter '

Base replacement [➙

 16]' 

2.  For information about configuring the detectors, see chapter 'Configuration of 

detector type [➙

 17]' 

3.  For information about carrying out function tests for detectors, see chapter 

'

Test the detectors [➙

 18]' 

 

 

 

WARNING 

Work carried out by personnel who are not sufficiently qualified 
Risk of explosion 

●

  Work in potentially explosive areas may only be carried out by qualified 

specialists or by specially instructed persons, in accordance with the national 

and international directives and regulations. 

 

 
Point detectors that can only be operated in collective mode are replaced with 

multiple protocol detectors. The detector lines are still operated in collective mode.
