5 Mounting / Installation
This chapter explains how you install the base for flame detector and how you
connect the flame detector to the detector line.
Prerequisites
The flame detector's mounting site is determined following to the details
provided in the 'Planning [ 27]' chapter.
The supply network is produced, connected and checked in line with the
country-specific installation guidelines.
Sequence
1. Switch flame detector over to collective operation [ 39] (if required)
2. Fit base for flame detector [ 41]
3. Electrical connection [ 43]
You will find information on the individual steps in the specified chapters.
The flame detector is only fitted on the base for flame detector when
commissioning.

5.1 Switch flame detector over to collective operation
When supplied the flame detector is set for operation on an FDnet/C-NET detector
line. When operating a collective detector line, the control panel normally
automatically switches the flame detector to collective operation.
Some collective control panels do not however automatically switch from FDnet/C-
NET operation to collective operation. In these cases, you must switch the flame
detector over manually. If you are not certain whether the flame detector is
switched over automatically, switch it manually to collective operation before
mounting.
The detector always switches automatically from collective operation to FDnet/C-
NET operation.
Procedure
Note the positive and negative poles.

The flame detector is not connected to the detector line.
1. Connect the base for the flame detector to a DC 12…28 V source of DC
voltage, e.g. a battery, following the connection diagram shown below. Use a
screwdriver to remove the load from the socket strip so you can slide in the
wire.
2. Remove bridging connector (2) from base for flame detector.
