gram.
A slider (37) in the relay module sets the type of the door opener.
Door opener of type „Fail Secure“ (working current door opener): Slider -> Position „NO“
This door opener is commonly used for apartment doors.
The trap lock of the door opener is only unlocked when operating voltage is pending, e.g. when the door
opener button in the apartment is pushed. Then the door can be opened and the visitor is let in. The door is
locked if no operating current is pending.
If the door opener works with direct voltage, observe polarity.
Door openers of type „Fail Safe“ (quiescent current door opener): Slider -> Position „NC“
This is a special door opener, e.g. used for a door to be used as an escape route.
The trap lock of this door opener is only unlocked when there is no operating current. This permits leaving
of the room in case of power failure since the door opener unlocks the door.
If the door opener works with direct voltage, observe polarity.
Important!
The outdoor unit works only with a stabilised direct voltage of 12 V/DC. Never connect an alter-
nating voltage (e.g. from a door bell transformer) to the outdoor unit or the relay module. This will
destroy the outdoor unit and the relay module, loss of warranty/guarantee!
