MrHappy Posted May 4, 2019 Share Posted May 4, 2019 that's the item... this unit had failed, a siren had been added inside the box which had also failed...

Seen a few of them. Don't know why they were made so big, since it is all slim electronics. Do you still think there is any market for bell boxes that use real bells?

sixwheeledbeast Posted May 4, 2019 Share Posted May 4, 2019 I fail to see why you would want mechanical devices that are quieter and can wear over a piezo.

Would have thought it was because they are more distinctive like the Piezo, I could have a go at designing something that looks modern and slim yet has a bell, like a EuroBell, just been thinking of manufacturing processes that could be used to make such a bell box..

MrHappy Posted May 4, 2019 Share Posted May 4, 2019 a bell is expensive & really heavy I'd assume a speaker & the sound of mechanical bell would be the modern way to do it Mr Veritas God Link to comment https://www.thesecurityinstaller.co.uk/community/topic/42729-start-an-alarm-manufacturer/page/10/#findComment-484163 Share on other sites More sharing options...

Just a standard speaker like an extension style speaker? I know of an amplifier circuit and would be able to find some sort of sound generation IC out there.
