Businesses which have large frozen food areas have air filled fire sprinkler
systems. A head pops, this releases the air pressure, then that activates a
water valve. Water then flows through the pipes.

And they of course don't want the alarm guy to test the flow switches on
these! Then they would need to drain the pipes to get air back in...
