system to operate on direct current supplied from a rectifier and storage
batteries. The exterior fire alarm reporting and receiving system shall
include the following features:
a.
A complete, electrically supervised, normally-closed series,
coded, positive noninterfering type of circuit.
b.
Succession features, whereby alarms from coded boxes [and
transmitters] are transmitted over box circuits to [the central
fire station] [fire alarm headquarters].
(1) Alarms that are [manually][automatically] retransmitted to
each branch fire station and to recording and sounding devices in
the system.
(2) Regardless of location, the first coded box operated shall
transmit four complete rounds of code without interference from
any other box.
(3) Other coded boxes that may have been operated during this
period and that shall then transmit one at a time as the circuit
becomes available until all boxes in an alarm condition have
completed four rounds of code.
c.
[_____] box circuits terminating in box circuit panels and alarm
panels arranged to automatically sound and record alarms from each
box circuit.
The central [fire station] [fire alarm headquarters] watch position shall
include [a desk and table,] receiving console with all associated switches,
printer, coupling units, alarm gongs, and other equipment.

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
