What is DK-9523 Keypad Manual (German) about?

Output 3 of the keypad is an open collector output that can be used for auxiliary controls like arming/disarming a security system. It can drive a relay to provide normally closed and normally open outputs like Output 2, allowing the keypad to function as a 3 output system. The appendix defines dry contact, normally closed, normally open, and transistor open collector output. It shows how an open collector output is equivalent to a normally open contact referring to ground similar to a relay contact.
