[ RadSafe ] Alarm on AMS3

[neildm at id.doe.gov]

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?
