level classification of Fire Station

[kelli]

Hello! I am designing a Fire Station and trying to determine whether or not it is considered Level 1 or 2 in relation the the ATS placement. Do I need to separate it from the normal power? Thanks!

From NFPA 110 2013

"4.4.1* Level 1 systems shall be installed where failure of the
equipment to perform could result in loss of human life or
seriousinjuries.
4.4.2* Level 2 systems shall be installed where failure of the
EPSS to perform is less critical to human life and safety."

I have read those and still feel like it is sort of a grey area. I am currently reading the NEC to see if I can get clarification. Even though they are able to get out of the building, if their 911 equipment fails, others might die. No?

that's not an NEC issue. the nec tells us how to wire the ATS.

I believe emergency egress lighting is level 1. So unless you have battery backup lights, you probably have a level 1.
Is the main electrical service over 1000 amps at 480V?

It is 120/208 3p with a 600a main service. It is the same Firestation I was asking about in which they want the entire station on the Generator. I did find the battery back-up Egress Lighting issue yesterday and found the part in the NEC that I was thinking about in which (unfortunately I don't have access to Electronic version of NEC), under the COPS area of 708.1 it is dependent on whether or not it is going to be considered a Critical Facility for Homeland Security, which actually opens up a whole other can of worms in which I have to design with all metal conduit and I don't know what all else. Is that how you understand it?

If they have a 911 center it is likely that you are dealing with a COPS (article 708) installation.
If this is not a COPS installation, then 'Life Safety' addresses the occupants of this facility only, such as the egress lighting previously mentioned by Steve66.
