Control methods involving pulse patterns
Control methods involving pulse patterns reduce the service life of the relay
contacts on the input/output module. Contact wear is also dependent on the load.
Up to 300,000 switching cycles are permitted.
At one switching cycle per second, 300,000 switching cycles are reached after
approx. 3.5 days.
Behavior in the event of an error (control panel-specific)
Error
Configuration option
Failure of 24 V power supply
Open (configuration not possible)
Error involving control panel (e.g.,
communication with control panel
interrupted)
Relay remains unchanged
Relay deactivated
Relay activated
Degraded mode horn function (only possible with control panels
FC20xx and FC72x)
In the case of the 'Degraded mode horn' function, the input/output module
accepts the 'Sounder ON' command. This function can only be configured on
control panels FC20xx and FC72x.
The monitoring of monitored control systems will only be resumed 30 seconds
after deactivation.
3.4.4.5 Control with confirmation
Control with confirmation is not supported by the following control panels or the
confirmation is not configured or processed on the control panel:
FC20xx
FC72x
AlgoRex
3.5 Diagnosis levels
The FDCIO223 input/output module monitors its operation largely autonomously.
The following diagnosis levels are derived from the different control measurements:
Normal
Observe information
Replacement recommended
Replacement necessary
Fault
For details, see table below.
When an error occurs which impairs the correct functionality of the module, a
module fault message is reported. The module contains additional information for
addressing the cause. This can be displayed by the FDUD292 detector exchanger
and tester or FDUD293 intelligent detector tester for example.
You will find more information in documents 007227 and 009718.
