Exposed over door contact

[Hulmerous]

Hi guys,could do with some advice on a matter I came across today on a job. It's to do with a over door contact that is installed from a bell chime unit with built in transformer. The door contact is the two metal strip kind so when the door opens the metal strips connect and sound them chime. My question is those metal strips are exposed to touch. The chime transformer output is 12 volt 1amp. Is that safe? I was always told that anything over 10ma is dangerous. Can someone guide me on this please?

Batteries? Things moved on from the days of the Leclanche Cells that that door contact probably first used.

In all honesty would you fit a battery bell in this day and age for use in a shop?

Arkwright had the best solution a bell on a spring.

We could go for the ultra safe method

They used to be a good band before him.

Still are. Maybe not as good as before but still good.

No No... just about every track off the Bon Scott albums is brilliant, apart from Back in Black, you can count the decent tracks since on the fingers of one hand.
Scott's lyrics are like Shakespeare to a Geordie Sun journalist!

They're still good though, like I say not as good but.....

I think I hear what your saying, still slightly deaf from seeing them at Leeds Poly, 1978, a few away from the stack stage right.
We sat on the wall outside for an hour or so waiting for us ears to stop buzzing.

There's some of my reports on there.
