Hi all, 

got a 4 loop advanced panel. loops all ok.

 

upload the device text with config tool, 

then suddenly loop powered sounds are going off, with nothing coming up on panel saying why or can’t silence them,  and only way to stop them is to just take loop out.

never come across this in 14 years, any ideas guys? 

Loop was fine before I done up load.

 

I’ve since erased the configuration via panel, so no devices then on loop, but still as soon as I plug loop in...sounders  go off!! 

 

Using Apollo gear with loop powered sounders only! 

 They are the right sounders they are not conventional! As they’ve been working while I’ve tested call points  before upload,

 

im going back in for a fiddle but any suggests  or anyone experiencing this would be a great help 

 

 

 

 

 

Are they integrated or ancillary base sounders? 

Integrated! This is wry odd. Made up a mini loop attached one sounder on it’s fine! Attach any of the 4 other main loops on sounder go off! 

Mist as if they are conventional sounders but they are 100% not.

its run for 3/4 weeks fine! 

Unless someone’s been in weekend and swapped then ha 

You running an old version of config tool?

After a bit of fiddling and leaving the sounders run while I went round to see if every one them was actually going off, they just stoped ringing after around 30seconds and calm was restored! Fully tested afterwards and work as normal.

very odd!
