12.6.4 Fire damper control properties
'Overview' tab
Specific properties for 'Fire damper control':
'Tolerance 'open''
A 'Fire damper control' element corresponds to a ventilation zone with a defined
number of fire dampers. The parameter determines the ventilation zone's
maximum number of fire dampers that must not be in the 'Open' position to allow
the fire damper control to accept the overall status 'Open'. In the default setting,
none of the fire dampers may be in any other status than 'Open' for the fire damper
control to record the overall status of 'Open'.
If the 'Main damper' parameter is activated for one of the fire dampers in the
ventilation zone, the fire damper control cannot switch back to the overall status
'Open' until this fire damper is no longer in the 'Closed' position.
The BACnet interface outputs the value for 'Tolerance 'open'' with the 'Control
HVAC' object.
Example of use
●
The 'Open' state of the 'Fire damper control' can be assigned as a cause for an
additional control in order to switch on a fan.
– NOTICE! Check that activating fans will not damage any of the channels
closed by dampers.
●
The 'Closed' state of the 'Fire damper control' can be used to check and ensure
that all fire dampers are closed in the event of fire.
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
