1.4.1.4
As-Built Drawings for the Fire Extinguishing System
Upon completion, and before final acceptance of the work, submit a complete
set of as-built drawings for the fire extinguishing system [, including
complete as-built circuit diagrams,]. Submit A1 841 x 594 mm 34 by 22 inch
reproducible as-built drawings on mylar film with 200 by 100 mm 8 by 4 inch
title block similar to contract drawings. Submit as-built drawings in
addition to the record drawings required by Division 1.
1.4.2
System Operation
Flow of water and AFFF shall be controlled by [deluge] [pre-action] valves.
Foam proportioning equipment shall activate automatically upon tripping of
the [deluge] [pre-action] valve(s) for the corresponding foam system(s).
[Deluge] [Pre-action] valves shall be tripped by independent detection
systems. No valve will be operated by the building fire evacuation alarm
system. Use of motor-operated valves is prohibited. Once activated,
system(s) shall operate until shut down manually. Provide separate
circuits from the control panel to each zone of initiating devices.
Transmission of signals from more than one zone over a common circuit is
prohibited.
1.4.2.1
Overhead Systems
Overhead systems shall be controlled by [deluge] [pre-action] valves
operated by automatic detection systems and by remote manual release
stations.
1.4.2.2
Monitor System
Monitor nozzles shall be controlled by deluge valves operated by [the
automatic detection systems and manual release stations which activate the
corresponding overhead system(s)] [independent ultraviolet-infrared (UV-IR)
optical detection systems and manual stations] [flow of AFFF solution in
the overhead system].
1.4.2.3
Hose System
Hose reels shall be controlled by deluge valves operated by remote manual
release stations, separate from those used for overhead systems and monitor
nozzles.

SUBMITTALS
**************************************************************************
NOTE: Submittals must be limited to those necessary
for adequate quality control. The importance of an
item in the project should be one of the primary
factors in determining if a submittal for the item
should be required.
A "G" following a submittal item indicates that the
submittal requires Government approval. Some
submittals are already marked with a "G". Only
delete an existing "G" if the submittal item is not
complex and can be reviewed through the Contractor's
Quality Control system. Only add a "G" if the
submittal is sufficiently important or complex in
context of the project.
