Do not commence work until the design of each system and the various
components have been approved. Show:
a.
Room, space or area layout and include data essential to the
proper installation of each system
b.
Sprinkler heads, discharge nozzles and system piping layout
annotated with reference points for design calculations
c.
Field wiring diagrams showing locations of devices and points of
connection and terminals used for all electrical field connections
in the system, with wiring color code scheme
[d.
UV-IR detector manufacturer's recommended detector layout (plan
view) including horizontal and vertical angles for correct aiming].
1.4.1.2
Calculations

relationship for sprinkler heads and discharge nozzles.
**************************************************************************
NOTE: Regarding the text below, consult with the
Division Fire Protection Engineer before specifying
2-wire smoke detectors as a Contractor option.
2-wire detectors must be carefully matched to the
control panel by the manufacturer, and are not
universally interchangeable between systems for
maintenance purposes.
**************************************************************************
c.
Substantiating battery standby power requirements calculations
showing battery capacity, supervisory and alarm power
requirements. [If 2-wire smoke detectors are proposed for use
show comparison of the detector power requirements per zone versus
the control panel smoke detector power output per zone in both the
standby and alarm modes.]
**************************************************************************
NOTE: Include the text below for Air Force Projects
only.

[d.
System surge analysis showing surge pressure occurring throughout
the system at both design flow and nonflow conditions.]
