REV. 1
Electronic data processing involves storage, recall and useof information via electronic equipment. Electronic data pro-
cessing equipment is found in almost every industry today.
The equipment is very sensitive and operates within minute
tolerances. Additionally, many computer installations are
designed with a subfloor area containing data and power
cable bundles.
Because of the high dollar valve of the equipment, the data
managed by that equipment and the productivity provided
by electronic data processing, rapid detection and efficient
fire protection are imperative. Time lost to cleanup and ven-
tilation of a computer room means lost time throughout the
company, so these areas require a clean, no residue gas
agent that disperses easily.
The computer room and subfloor space can be protected
with an SAPPHIRE suppression system, even when the
computer room is normally occupied.
Fires can occur within the computer electrical insulation and
in the cable bundles in the subfloor. Paper debris that has
been allowed to accumulate in the subfloor is also a source
of fuel.
Computer room/subfloor protection can be accomplished by
installation of a total flood SAPPHIRE system. The
system is designed in accordance with the ANSUL design,
installation manual and NFPA Standard 2001, Standard for
Clean Agent Fire Extinguishing Systems. It is importantthat an effective agent concentration not only be achieved,
but shall be maintained for a sufficient period of time to
allow effective emergency action by trained personnel.
The SAPPHIRE system consists of a tank(s), a piping
arrangement and discharge nozzles located in the comput-
er room, storage room, and subfloor space.
Occasionally, drainage is installed in the subfloor area.
Provisions must be made for making the drain piping a
closed system unless water is present to assist in assuring
the necessary concentration.
When the computer room is normally occupied, personnel
safety is of first concern. Alarms or warning devices mustbe located in the room to provide sufficient annunciation of
agent discharge. The rooms and subfloor must be tight to
prevent loss of agent.
All air handling equipment must be shut down and
dampered prior to system discharge.
Smoke detectors, operated by an electronic control panel,
are usually employed with a SAPPHIRE system to provide
detection and thus suppression of a fire before it has a
chance to do serious damage.
The authority having jurisdiction may have additiona
requirements.
