Hi,

 

I installed a 9651en43 with a pyronix deltabellX, Tests fine during day, but I suspect on a night if mains fails the bell box light is dropping the voltage or some other fault and if running on battery it activates the bell.

 

I need to meter  the voltage on the bell trigger -  but not sure what terminals to test. Im guessing bell trigger but which other terminal?

 

Also the panel doesn't seem to detect when mains voltage fails and it moves onto backup battery nothing displayed,lit or logged when mains fails on the 9943 panel. Also the mains healthy light on panel has never illuminated but has been running for weeks now so its got mains power

 

Any help would be appreciated.

 

Many thanks

Something sounds not right there.

Is the panel 2nd hand as this is not the current version.

Whats your day mode current, is it overloaded?
