I suppose it helps if you know all the features to find the "glitches" then...
Now you mention it I understand where you went wrong with your Duress.
PA Alarm would be the correct output to use for a Duress, PA Silent would only trigger on a "silent" zone whereas PA Alarm is any Panic event including Duress, so that's another "glitch" that wasn't.
You need to start again with the wiring. It's too messy. Solid cores are too brittle too. Spend £15 on alarm cable.
Connect three cores only at the panel. Say:
+12v - brown
0v at the zone - blue
The zone input - green.
At the sensor, connect
Brown to +12v
Blue to 0v. Now loop a wire from 0v in the sensor and connect it to NC.
Connect a 1k resistor from NC to C
Connect another resistor between C and T1.
Connect the green wire to T2.
LOL this place is full of sarcasm and satire, you do know that this is a security industry forum right?
If you can put up with the humour, and you're prepared to put in as much as you get back you could find this site useful.
I think he was referencing the ease of them bending over and resetting over the phone, makes a mockery of having a code regardless of how often it changes.
