[ RadSafe ] Alarm on AMS3

[Robert J Gunter]

You might consider putting foam on the bell, or foam tape on the inside of
the bell.

Good luck!

In theory, the striker for the bell could be adjusted by bending to lessen
the impact and reduce volume, but it would be a fiddly adjustment if it can
be done at all.  This is assuming the bell works like most electric bells
I've seen.

If the unit you have uses a large bell on side, then you're going to have to
remove it and either replace it with something a little quieter or use an
external device to make whatever level of noise you prefer. 

The AMS3 does have alarm outputs you can use with some other device -
perhaps an external Sonalert from Mallory?
