I had a very pleasant conversation with a fellow at SH yesterday. I
explained what I wanted to do re. the flush mount and he said it would
work. He volunteered to send screws and template to me. I also told
him about the internet discussions about alarm volume. I told him
that like me, many "geezers" can't hear all that well and suggested a
jack for an external speaker be added or a louder alarm with a volume
adjustment. He thought is was a very good idea and was going to
forward the info to the manager of product development.
