Fire Safety
2016-05-04
The input/output module is meant to respond quickly in test mode/inspection mode.
Consequently, the lines are operated as follows in test mode:
With detector lines, the alarm verification is deactivated
With contact inputs, the filter time is deactivated
Error messages are transmitted immediately and are not filtered
Depending on the version of the market package of the fire control panels FC20xx
and FC72x, the procedures described are carried out either on the device or on the
control panel.
Localization
To enable clear identification, the input/output module FDCIO223 can be set to
localization mode from the control panel. Localization mode is signaled by the
yellow LED (12b) for the primary side status display.

3.3.5 Earth fault monitoring
The secondary side is monitored for ground faults regardless of mode. Ground
fault monitoring can be deactivated with a jumper. The setting for ground fault
monitoring always applies to both inputs/outputs.
Switch off ground fault monitoring if a safety barrier SB3 with intrinsically safe
detectors for potentially explosive atmospheres is connected.
NOTICE
Ground fault monitoring is switched off with outputs activated.
