13 : DOOR SENS (Door Position Sensing Input -- Normally Close)
A Normally Closed (N.C.) sensing point referring to (-) ground, with the help of a normally closed
magnetic contact monitors the open or close status of the door. It initiates the following functions for
the system. Connect it with jumper to (-) Ground if not used.
a) Door Auto Re-lock
The system immediately re-locks the door after it is re-closed before the end of the programmed time
for output 1. It prevents unwanted “tailgate” entry.
b) Door Forced Open Warning
The keypad generates “door forced open” warning instantly once the door is forced to open without
a valid user Code, Card or egress button. The warning lasts as long as the time programmed (1-999
sec). It can be stopped with an User Code or card for output 1 at anytime. See programming Location
80 for the details.
c) Door Propped-up Warning
The keypad generates propped-up warning beeps while the door is left open longer than the
allowable time programmed. The warning will last as long as the door is open until re-closed. See
programming Location 81 for the details.
d) Inter-lock Control
The inter-lock control output always goes to (-) while the door is open, which gives signal to disable
the partner keypad in an inter-lock system. See the Inter-lock terminal 10 description for more
information.
14 : DATA I/O (Data Input/Output Communication Bus)
Data I/O port is prepared for setting up a data bus for the connection of the auxiliary reader-keypads
and the split-decoder in system expansion. See the examples in “Application Expansions” section for the
details.
15 - 16 : TAMPER N.C. (Tamper Switch Normally Closed Contact)
A normally closed dry contact while the keypad is secured on its box. It is open while keypad is
separated from the box. Connect this N.C. terminal to the 24 hour protection zone of an alarm system
if necessary.
