Code” or the “Common User Code” to operate the specific output and report a duress alarm event. 

Programming is not required. The system has this function automatically while Duress Code exists.

           (a)                        (b)                    (c)

and 42 for Output 1 and 2 respectively)

(c) Confirm it with the # key. The specific Output activates in a normal way and the Duress Output 

also activates to report Duress Event to an alarm system.
