Are your jurisdictions requiring standby power for elevators where a required accessible floor is four or more stories above the level of exit discharge?
 
03' IBC 403.10 and 403.10.2 would appear that all elevators require stand by power. Low rise is defined in chapter 16 of the IBC. Just additional information under IBC. Stand by power requirements section 2702 reference NFPA 110 and 111 and elevators chapter 30.

Section 403 is for "High Rise Buildings":

403.1 The provisions of this section shall apply to buildings having occupied floors located mort than 75 ft above the lowest level of fire department vehicle access.

403 applies to High Rise buildings, not low rise. I can't seem to find a definition for low rise in my 2003 IBC.

Does the OP mean high rise?

I'd guess that anything that isn't high rise is low rise. See my quote from 403 above. (Typo's and all!)

IBC 3003.1.2 "Where one elevator is installed (required or not.. mho, anyway) ... the elevator shall automatically transfer to standby power within 60 seconds after failure of normal power... "

If it's there.. I think it needs standby power (certainly if it's a REQUIRED elevator)

This was not even an electrical code question, really... it's a building code question, which I answered... (the question was not how to wire the darned thing)

If you talking about the PM system being down you may be interested to know it has nothing to do with the Moderators. It seems you are not the only one having PM system troubles.

elevators

thank you, oh moderator..

I'm just trying to tie the building code into everything else that goes into a building.. (well, including those dog gone elevators.. doesn't really matter if they are required or not... Chapter 30 of the IBC addresses them)
 
I can't give you chapter and verse, but the fire marshal, a good friend, tells me that anything 4 stories and above shall have the elevator(s) on a generator. He is the second jurisdiction to tell me that so I guess it's widespread. Guess the generator people are grinning all the way to the bank. I have a 5 building condo complex that has to have just that. I have put off working on this job for this reason and I am waiting on the 50% payment. #$%^&*, collecting engineering fees is next to impossible all too often! ANYway, I just don't know what the best approach is. One big generator or 2 or more smaller ones. Is the elevator considered "life safety" under Art 700? Or is it under 702? Arggg. RC
 
George,

I will be working just down the street from Homeland Security........should I walk right in and ask them whats up with the PM ?.......mine is gone also. I must have been a "bad boy"

But somewhere above 3003.1.2 you will find something that says something like "where required or provided."

So if the building isn't a high rise (like section 403), and you can't find anything else that says its required, and you don't elect to provide emergency power, then 3003 doesn't apply.

Look at my first post in this thread. A 4 story building would probably exceed the 75' height. A 3 story building probably would not.

Sorry folks I realize this is a building code issue. Section 1007.2.1 of the 2003 International Building Code provides the following:

1007.2.1 Buildings with four or more stories.In buildings where a required accessible floor is four or more stories above or below the level of exit discharge, at least one required accessible means of egress shall be an elevator complying with with Section 1007.4.

This requirement is not found in the Life Safety Code (NFPA 101). I found on-line that Seattle, Washington permits a tap ahead of the service disconnecting means. I was wondering what other jurisdictions are doing.

Any help is greatly appreciated.
