SECURITY AREA CLASSIFICATION
The installation of security lighting is set forth in
United States Navy Physical Security Manual,
OPNAVINST 5530.14. It provides specifications on
searchlights and minimum footcandle requirements
under given situations. The illumination of
boundaries, entrances, structures, and areas must be
according to the security manual.
Each security lighting system is designed to meet a
particular need of the activity. The design is such that it
provides the security required at maximum economy.
Multiple circuits may be used to advantage here.
The circuits are so arranged that the failure of any one
lamp will not darken a long section of the area. The
protective lighting system should be independent of
other lighting systems and protected from interruption
in case of fire.
The switches and controls of the system should be
locked and/or guarded at all times. The most effective
means is to have them located in a key guard station or
central station similar to the system used in intrusion
alarm central station installations.
ALTERNATE POWER SOURCES
In general, any security area provided with
protective lighting should have an emergency power
source located within that security area. The
emergency power source should be adequate to sustain
all security requirements and other essential service
required within the security area. Provisions should be
made to ensure the immediate availability of the
