signature, shall cause operation of the system trouble signals. Logic
circuits necessary for operation of the detector shall be integral to the
detector or located in separate flame detector control panel(s) located
adjacent to the foam system control panel(s). Each detector in alarm shall
be individually annunciated by an LED on the detector or at the detector
control panel. Primary and auxiliary power supply shall be taken from the
foam system control panel(s). Detectors, and associated control panels if
required, shall be compatible with the foam system control panel(s).
Detectors and associated control panels shall be weatherproof, or housed in
weatherproof enclosure(s) when in an area subject to system discharge and
shall also be explosion-proof when located in hazardous areas as defined by
NFPA 70. Detector spacing and location shall be in accordance with NFPA 72,
their UL listing or FM approval, and the manufacturer's recommendations.
The detector manufacturer shall determine or approve the detector layout.
Detector layout drawings shall include horizontal and vertical angles for
correct aiming. Locate detectors so that every portion of the protected
area is within the field of view of at least [two] [three] detectors,
taking into account fixed obstructions. Provide detectors with
manufacturer's swivel mounting bracket. Provide a permanent engraved rigid
plastic or metal label at each detector location with detector aiming
information (degrees horizontal and vertical) for the corresponding
detector.

ELECTRICAL WORK
**************************************************************************
NOTE: Edit Section 16402, "Interior Distribution
System" and include as part of the project
specification.
**************************************************************************
**************************************************************************
NOTE: When project includes requirement for a
building fire alarm system, include Section 13852 in
the project specification. When project requires
only tying into an existing building fire alarm
system, fire alarm wiring should be specified in
this section. For Navy projects, select the first
13852 Section title when using the basic NAVFAC
guide specification covering the subject work or
select the second title when using the EFD regional
guide specification covering the subject work.
**************************************************************************
Electrical work is specified in Section 16402 INTERIOR DISTRIBUTION SYSTEM,
except for control [and fire alarm] wiring. [Fire alarm system is
specified in Section [13852N INTERIOR FIRE ALARM SYSTEM] ["Fire Alarm and
Fire Detecting Systems (Local)"].]
2.10.1
Wiring
Provide control wiring and connections to fire alarm systems, under this
section and conforming to NFPA 70 and NFPA 72. Wire for 120 volt circuits
shall be No. 12 AWG minimum solid conductor. Wire for low voltage DC
circuits shall be No. [14] [16] AWG minimum solid conductor [, except wire
to remote annunciators, if provided, may be 18 AWG minimum solid
conductor]. All wiring shall be color coded. Wiring, conduit and devices
exposed to water or foam discharge shall be weatherproof. Wiring, conduit
and devices located in hazardous atmospheres, as defined by NFPA 70[and as
