Shamelessly stolen from the NICET Fire Alarms Facebook group:
Which is more important, a sprinkler system or a alarm system AND WHY?
Both are important, and ideally you should have both. But if you could only have one, which would it be and why?
Probably a sprinkler system I’d imagine, since a sprinkler system will actually control & maybe even extinguish a fire: smoke alarms & fire alarm systems both give warning of a fire, but do nothing to actually control it.
I’d rather go with Novec 1230, since according to 3M it’s got so many advantages compared to virtually all other fire suppression agents & seemingly no downsides.
