OPERATION AND FUNCTION OF THE DURESS CODE

The Duress Code(s) has double actions when it is keyed in. It activates the Duress Output (for duress 

alarm) and at the same time activates the specific Relay Output 1, 2 or 3 just like a normal User Code. 

The Duress Code always activates the Relay Output in its group, but, does not de-activate (stop) the 

Duress Output. 

ONLY a normal User Code or Card in anyone of the user groups, or a Super User 

Code

 can reset (de-activate) the Duress Output.

For Example:
Key in The Duress Code 3 3 6 9 of the Group 1 (for Output 1) To Command The Duress Function :

                         ----- Duress Output activates (switches to (-) ground) & Output 1 activates.

Key in The Duress Code 3 3 6 9 in Group 1 (for Output 1) Again :

                         -----  Duress Output keeps activating and no change in its state (keeps to (-) 

Key in A Normal User Code to Reset Duress (For Example: 1369 is An User Code for Output 1):

                         ----- Duress Output resets (back to OFF state) but does not activate Output 1.

(iii) Pause the real-time inhibition manually

The real-time inhibition can be stopped temporarily if require; such as the staff work overtime in 

office. The inhibition can be paused manually with Super User Code before or during the 

inhibition period. The pause is toggle and does not affect the real time period counting.

                                                   ---- Inhibition paused [Inhibit LED(Red) Flashing]

                                                   ---- Inhibition resumes [Inhibit LED(Red) ON]

NOTE:

The “INHIBIT” LED(Red) is flashing during the paused period; and it is ON after inhibition resumes.

(iv) Open door lock with Super User Code at anytime

The Super User code is valid all the time even in the inhibition period. This function does not 

affect the real time period counting.

                                                   ---- The door is open

Programming and Operation Examples:

(i) Set the starting and stopping time for the real-time inhibition period

    a) Set Inhibition Period from 12:30 PM (today) – 1:30 PM (same day) for lunch time:

    b) Set Inhibition Period from 6:30 PM (today) – 8:15 AM (next day) for office close:

NOTE:

1) The start and stop time figures are 24 hours basis. They are 4-digit figures from the smallest 

00:00

 to the largest 

23:59.

2) Entry of the two figure values from 

Small

 (Start) to

 Large

 (Stop) for the period of inhibition; the 

inhibition will start and stop in the same day. See 

example (a)

.

3) Entry of the two figure values from 

Large 

(Start) to

 Small 

(Stop) for the period of inhibition; the 

inhibition will start at the time of the day; thus stop in the next day. See 

example (b)

.

4) The keypad does not accept the “Start” and “Stop” times with same value. The two time figures 

must be different.

(ii) Clear the function of inhibition

 

Clear the time settings to stop the function of inhibition:
