The product range includes bases with or without a loop contact.
If an C-NET device is removed, the loop contact prevents the C-NET detector line
from being interrupted and thereby prevents a fault message.
The work described in this chapter may be performed when the C-NET detector
line is switched on.
It may be possible that an C-NET device must be temporarily removed from the
base. Afterwards the same C-NET device must be re-inserted at exactly the same
place in the C-NET.
Document the serial number or address and the position in the C-NET for each
device in order to enable the device to be placed in the same position following its
removal.
1. Remove the C-NET device.
a The control panel detects that the C-NET device is missing and reports a
'Fault'.
2. Perform the necessary activities.
