Does this mean you could drive around with a (illegal, but not difficult to

parabolic dish, aim it at random buildings and set off peoples' halon
systems?  Wow.

I'd like to think it's been fixed.

Then again there are those Blasting Zones one goes thru on highways
with big signs ordering drivers: NO CELLPHONE USE! BLASTING ZONE!

Sounds like a good plan.

About the worst that ever happened to me was a security guy's
walkie-talkie setting off an instant Halon drop. Cost about $10,000 to
refill and was fairly exciting for those present. That also cut the
machine room's power.

At least it didn't set off the sprinkler system.

We sat down with the Halon system vendor to find out why that happened
after proving, on a by-passed system, that yes indeed one of these
common walkie-talkies sets the thing off.
