Appendix
1. DRY CONTACT --------
A dry contact means no electricity was connected to it. It is prepared for free
connections. Usually the relay contacts provided in a keypad are dry contacts.
2. N.C. ------------------------
Normally Closed, the contact is closed circuit at normal status. It is open circuit when
activated.
3. N.O. ------------------------
Normally Open, the contact is open circuit at normal status. It is closed circuit when
activated.
4. TRANSISTOR OPEN COLLECTOR OUTPUT --- An open collector output is equivalent to a Normally Open (N.O.)
contact referring to ground similar to a relay contact referring to ground. The
transistor is normally OFF, and its output is switched to ground (-) when activated.
The open collector can only provide switching function for small power but it is
usually good enough for controlling an alarm system.
The Duress Output is Open Collector Output.
