SYSTEM DESIGN
System shall be a complete base-wide public fire reporting system,
complying with NFPA 72, except as modified herein. The exterior fire alarm
reporting and receiving system shall comply with NFPA 72 [2], [3], [4],
[5-8]-line Hunt Group. The system shall consist of digital alarm
communicator transmitters (DACT) at each protected premise and digital
alarm communicator receivers (DACR) at the fire alarm receiving station
located at [_____]. The system shall be supervised such that any telephone
line connected to a DACT which fails due to loss of line voltage shall be
annunciated at the receiving station. The system shall be designed to
operate from direct current supplied from a rectifier and from storage
batteries. The system shall be designed to record alarm and trouble
information from each DACT as well as supervisory alarms received at the
DACR. Provide spare DACRs in accordance with NFPA 72. Connect system to
existing [and new] local building fire alarm systems, [and] [sprinkler
water flow detectors] [and] [existing] [manual pull stations] [and]
[existing extinguishing system control panels] as shown to form auxiliary
alarm systems in accordance with NFPA 72. [New local energy fire alarm
systems are specified in Section 13852N INTERIOR FIRE ALARM SYSTEM.]
[System shall include [street boxes] [and] [master boxes] as specified
herein and where shown, to allow manual initiation of fire alarm
transmission by the general public.]

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.
For submittals requiring Government approval on Army
projects, a code of up to three characters within
the submittal tags may be used following the "G"
designation to indicate the approving authority.
Codes for Army projects using the Resident
Management System (RMS) are: "AE" for
Architect-Engineer; "DO" for District Office
(Engineering Division or other organization in the
District Office); "AO" for Area Office; "RO" for
Resident Office; and "PO" for Project Office. Codes
following the "G" typically are not used for Navy
