Damper Control States; Assignment Of Effects Dependent On Wiring - Siemens FS720 Configuration

12.6.2 Damper control states

12.6.3 Assignment of effects dependent on wiring

Building Technologies
Fire Safety
The damper control state and the display of this state on the PMI are dependent
on the parameter value for 'Tolerance 'open'' OR on the state of the 'Main
damper'.
Fire damper control
Fixed state: It is not possible to change the assignment between the state of the
control and the state of the fire damper.
Control state
Inactive
Active
Smoke damper control:
Changeable state: The assignment between the state of the control and the state
of the smoke damper can be inverted if wired accordingly. The table below shows
the default state that applies in each case:
Control state
Inactive
Active
You will find more information on the message texts that are displayed on the PMI
when a damper control is activated, deactivated, or malfunctions in document
A6V10211076.
The assignment of effects is dependent on how the FDCIO222/4 is wired to the
contacts of the fire/smoke damper actuator.
An output with monitoring must be configured for each damper. The output
without monitoring is optional and is only required if you want to connect the
damper actuator to the FDCIO222/4 using both poles.
Monitoring the control with the inputs of the FDCIO222/4
With the FDCIO222/4, it is possible to monitor whether control of the damper
actuator (e.g., 'Close damper') has been performed correctly (e.g., 'Damper
closed'). Motor 'M' of the damper actuator is controlled via one output (fire damper)
or via two outputs (smoke damper) on the FDCIO222/4. The damper state is
monitored via two inputs on the FDCIO222/4. You will find more information in
document 007023. See chapter 'Applicable documents'.
