Got called out to this today. Bell faulty and 15 min cut out not working. Removed power and had to leave on battery. God knows how long before that runs out. Told customer to call sign people out so we can access our bell. Can't believe how thick some people can be installing that sign over bell box.

Do those bells have huge 1.2Ah yuasas like the initial ones?

No they have a built in nicad

Still, I expect it'll last until at least 3am 

 

When I went back to an out-of-contract customer having a loft extension last week (I was there for 2 days in the end, in part due to what you're about to read), builders were about to attempt to chop around a twin alert and a smoke by moving them still attatched to the plasterboard!!

did you not remove all the sounder connections from the panel?, usually they have a cut off point after 15 mins?

need to knock off power, disconnect panel battery & then disconnect sounder cables, be careful not to touch the strobe connections as these can be around 300V

Matt Please re read )

oh i see lol, maybe could do with some ear defenders and move the battery test link?

If I could remove the battery link I could replace the bell complete could I not

well that's what id do, always keep a spare sounder, on the other hand its a nuisance so would either do something with the link or even cut the cables from the battery inside the sounder  

You don't get the picture do you.
