I can imagine they are scrambling to find ozone safe replacements ...
FM200 is the "new Halon" for computer rooms.
At work the existing Halon system was pulled out for environmental reasons and a two stage suppression system was put in.
The first stage is a cross zone trip FM 200 system connected to the Emergency Power off system for the data centre and printer room.
The second stage is a dry pipe sprinkler system. The reasoning is if the FM200 malfunctions or does not put the fire out immediately, the heat of the fire will trip the sprinklers and save the rest of the office tower from the fire.
Our unmanned backup data center is strictly FM200 as its a standalone building out in the suburbs not on city water. It tripped this spring and the vendor is still not sure why it did that as there was no fire in the building.
A girl I was going out with in the early 1980's was caught in a Halon dump in the Provincial government data center as she could not make it out the exit door in time when the pre alarm sounded. She dived under a desk in the tape library as all the suspended ceiling blew apart as it was not clipped down properly. Parts of the cross tee's were embedded in the drywall from the discharge force when the fire department came to search for her. Other than being scared for her life while everything was blowing around she was ok.
