Ya, and you had to hold the test for a specified time without any air/halon leaking out. If you are building a new POP, HALON in ANY city is not legal any more. The bad news is there are still a few major areas that have not approved the HALON substitute. So you end up with a pre-action water system with high temp heads.
Are you discussing Ansul's Inergen? My understanding was that it's composition didn't _require_ any regulatory clearance, being mainly Nitrogen. The only problem I knew of was that you couldn't liquify it, so it took more space to store than Halon. Cheers, -- jr 'looked like neat stuff, actually' a -- Jay R.
