pyronix - deltabell external sounder - keeps going off? when i put on alarm code

[kyrusdemnati]

i have paired my deltabell external sounder (see previous posts)

problem i have now is whenever i enter my alarm code - the external sounder goes?
when i do enter the code

it does bring up a message on the display

Testing....
and then the standard now arming message...

there is no alert about the external deltabell being triggered on the display panel and re entering the alarm code does not turn it off either. i have to access engineer menu and and exit and then it says 'saving nvm data' and it turns off

problem i have is i cannot set the alarm in either of my zones without the external sounder immediately going off?


any advice on how i can fix this please?

How long does it activate for if you leave it?
