same prob here. 20% buzz. psu tight , solid fixings to wall etc, wont use em anymore.

Had another problem using eol method, if its used on smokes or pa's you get a tamper sometimes three days later,although often sooner. You automatically think its a fault and check everything only for it to happen again. Cooper deny the fault totally. Ive had many occcasions when mates have fitted them and I always laugh when they say theyve used eol , as soon as smoke or pa is mentioned i get the fiver out, never fails . If you gotta use em double pole em.

They weren't texecom smokes were they?

If so there is a known problem due to them being able to be used as '2 wire', they must be double poled.

I put in 98 once while on a call out in the middle of winter without the book, I went up like a lighthouse!

92 to test strobe 91 bells, we've still got some out there going strong until the next lighning storm!

has anyone else had problems with scantronic panels namely the psu buzzing

we fit a lot of 9651 panels to new build propertys and have found that few shortly after comission start to buzz realy badly?

i have got in touch with scanyt and they are saying they dont know about any probs with psu's ??????????????

so can anyone back me up?

I had the same problem with a 9651 when they first come out. Tried putting insulation on the fins but only quietend down a bit. Just replace the transformer and sent the other one back. All was fine then!

forgive my ignorance on scanny but what does 98 do?

im not an installer of scanny so thats why im asking.

thanks

defaults the panel! can be your worst nighmare
