Built-in electric lock release with automatic operation (A) and 12V AC activation: it unlocks automatically when voltage is received and it locks again once the power is stopped and the door is mechanically opened and closed again. The lock release is integrated in a type S frame, to be embedded in the wooden or metal door frame.
The Series 300 of door openers is characterized by its more robust design, whose dimensions are: 90(V)x20(H)x28(P)mm without armor. With armor they would be 160(V)x25(H)mm. It is a reversible lock release, that is, it allows opening both to the right and to the left, but taking into account that the body does not keep symmetry with the change from DIN Right to DIN Left.
