Re: Ever done this?

One very embarrassing moment for me was a demo to a teacher in our school,
who had just set off a false panic alarm . After the staff and students were
calm and settled, I went to the room that sent the panic and talked to the
teacher.  Look, I told him, you have to hold the button down for two seconds
(5802MN) to set off the alarm. Watch, I said.  Push, push, push,
SIRENS!!!!!!!!!   What a way to find out the remote samples at two sec, and
doesn't care what you do in between!
