Configuration fire/smoke detector
10.1
FD (fire detection) function (alarm/emergency)
If the FDC (Fire Detection Contact) is activated, the door will close because the voltage to the electric
brake on the drive unit will be cut. Under the default factory setting, the door will lower until it
reaches the end switch close. If the door must descend past the end switch close or must stop at
another position, the end switch (S6) must be used as an “over-close” end switch.
If communication between the controller and DES is lost on a controller with digital end switch DES,
the door will close without end switches!
-
The normal open button can be switched on or off via parameter 3.3 in case of
alarm/emergency. If this button has been activated in the menu, the door will open in “hold
to run” when it is pressed. The door will immediately close again when the open button is
released.
-
The fire detection function can be activated with a delay. This can be done via parameters
4.5 and 4.6. The door will only be closed after the configured time.
-
A pre-warning can also first be given with a configured time for the ‘fire detection function’
and the ‘close in case of power failure or low battery voltage’ option. This time can be
configured using parameter 2.8 (0 to 60 seconds).
-
The fire detection function can be extended once the FDC input has closed again. This can be
configured to between 0 and 240 seconds via parameter 3.4.
-
An input is available for connecting the escape button. The door will open if this button is
operated. This can be completely open, or the extra end switch can be used to configure an
intermediate position so that the door opens halfway (set parameter 3.1 to 3).
-
The door will close once the waiting time (1 to 240 seconds) configured in parameter 2.2 has
passed. During the configured waiting time, the close button can be used to immediately
close the door.
-
The intermediate position can also be used to make an interim stop (parameter 4.1) if closing
when the FDC contact is active. In this case, the door will first close to this position, and will
wait for the time configured in parameter 4.2 before it continues to close.
10.2
Continue running if battery empty (only for digital end switch DES)
It is possible to raise the door again if it has gone past the end switches and has reached the
emergency end switches (because the batteries were empty). This is only possible during normal
operation by pressing the Up button on the circuit board for at least 5 seconds. After 5 seconds, the
door will open in “hold to run” mode and can thus be placed back within the end positions.
PLEASE NOTE!
The end positions are not monitored in this function! Make sure that you release the button on
time.
PLEASE NOTE!
