The electric current produced by some intercoms can be high, keeping the lock open
even after the opening button has been released.
This can be verified by determining if 12V AC is measured on IN1 even after the
button has been released. It is advisable to interface the intercom with a repeater
relay and connect the motor as shown in diagram 3 if necessary.
