Alarm Delay with Zone opened

I am using any Zone on my Konnected board to activate the ALARM output (identified as a SIREN/STROBE).

Then I use CoRE to activate this 12V output when a door is opened, sometimes it does not activate, and sometimes there is a few second delay.

What routine or setting could I use to make the SIREN output turn on the fastest?


I actually wired a 12V relay to the alarm ouput and want to turn it on INSTANTLY when the door is opened, and then turn off the alarm output 1 or 2 seconds later.
