RE: Fire protection in ISPs and collocation facilities
There are a lot of non-fire reasons that I like the presence of an EPO switch and I would design one in regardless. However, its requirement in the fire-code makes the expense easier to justify. I design framerooms with many smaller UPS's distributed throughout the racks, as opposed to a central pile of batteries. As a result, I have gel cells everywhere. I usually use Liebert GT's, every two racks, with power pod and interlock, at the bottom of the rack. Some of the non-fire reasons; Ground-faults placing 120VAC on the rack frames. Flooding event. Data intrusion prevention (Emergency SCRAM). > From: Sean Donelan [mailto:[email protected]] > Sent: Saturday, November 04, 2000 5:56 PM > > Several people have asked where can they obtain a copy of the US > Air Force draft. > > Engineering Technical Letter (ETL) 00-3: Fire Protection Engineering > Criteria - Electronic Equipment Installations > > http://www.afcesa.af.mil/Publications/Drafts/ETL00-3Draft.pdf > > I find it interesting how the designs created by people who have to > operate an installation are different from the designs from > consultants > and vendors, or even the National Fire Protection Association.
