Fire Alarm Zones
(OP)
I have a question regarding NFPA 72 2002 section.
In the appendix A.4.4.6.1.2 section (5)
it states that the floor area shall not exceed 22,500sq.ft.
and any length of 300ft in any direction.
Then it says if it is sprinklered, the area of the zone should be permitted to coincide with the allowable area of the the sprinkler zone. Which I read as 52,000 sq.ft.
Are there any other implicit limitations?
Does the 300ft. rule still apply?
How does this impact my number of and location of things like my DGP panels etc?
Thanks in advance!

also with an addressable system each device tells you where the problem is
Also remeber what that particular section is about
You might also check the 2007 edition to see if any changes
