1. Fire Extinguishing System - Designs and cost estimates shall be prepared
for installation of each of the following two systems:
a. Halogen ("Halon") System similar to the system currently being installed
in computer centers at the home office of the UNIVAC Corporation. Note: Halon
is the safest (least toxic) gaseous extinguishing agent available and is especially
suited for protecting electronic computer equipment because it leaves no residue
and therefore eleminates costly after-fire clean-ups. Halon is approved and meets
the standards of the National Fire Protection Association (NFPA)(Standard No. ]2A).
b. Wet Sprinkler System similar to the existing systeiTNTL
incorporating the following features:
The entire Computer Room shall comprise a single zone.
? Recessed type sprinkler heads shall be installed and protected with
metal guards to prevent operation from an accidental impact. If metal
guards cannot be supplied by the sprinkler manufacturer as a standard
option with the recessed type sprinkler heads, then guards shall be
specially fabricated by the contractor.
To permit easy testing and flushing of the sprinkler system, the end
of each sprinkler branch line shall be connected to a header which runs
