10. Circuit Examples
a) Simple Door-Opener Switch
The emergency power supply has two connection / switching channels that are independent
of each other. Observe the labelling on the board for using the correct channel each!
If the door opener button is pressed
in the apartment / house, the door is
unlocked electromechanically.
This basic function is also available
during a power outage if a lead bat-
tery is installed and charged in the
emergency power supply.
It depends on the door opener used, which contact ("N.C." or "N.O.") is used.
Door opener with "Fail Safe" function: If no battery voltage is applied, the door opener is
"open", i.e. the door can be opened. Use screw terminal "N.C." for connection.
Door opener with "Fail Secure" function: If no battery voltage is applied, the door opener
is "closed", i.e. the door can not be opened. Use screw terminal "N.O." for connection.
Connect the door opener button (usually "N.O." button, closer) to the "Lo CONTROL" and
"GND" screw terminals (see figure above). Several buttons can be switched in parallel.
Put the "Lo" jumper for the respective connection / switching channel in the "I" position each.
Use the rotary control "TIMER" of the corresponding connection / switching channel to set the
activation duration of the door opener in the area of 0.5 to 25 seconds.
