13 : DU OUT (Duress Output)

An NPN transistor open collector output with maximum power rating of 24VDC/100mA sink. It is

equivalent to an N.O. (Normally Open) terminal switching to (-) ground after the Duress Code is

entered. Use it to trigger an alarm zone of a security system, or turn on a buzzer to notify a guard.

14 : (-) GND (Common Ground)

A grounding point of the keypad that is common to terminal 4.

Keypad Active Output (“K”) --- It switches to (-) ground for 10 seconds on each key touch. It

can be used to turn on light, CCTV camera, or buzzer to notify a guard. See Application Hints for

more information.

Alarm Output (“A”) --- It switches to (-) ground while Alarm occurs in order to trigger external

alarm to give notification at remote location.

15 : DOOR SENS N.C. (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

b) Door Forced Open Warning

c) Door Propped-up Warning

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.

The keypad generates “door forced open” warning and alarm 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.

The keypad generates propped-up warning beeps (does not activates alarm output) 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.

12 : “K” OR “A” O/P (Keypad Active Output or Alarm Output)

An NPN transistor open collector output with maximum power rating of 24VDC/100mA sink. It is

equivalent to an N.O. (Normally Open) terminal referring to ground. It can be used to drive small

power device, such as a relay or a low power control point for other equipment. This output point is

selectable to give Keypad Active Output or Alarm Output via the “K or A” jumper.
