PART 1 GENERAL
NOTE: This specification does not include provision for high-mast roadway and
parking lot lighting (poles over 18.3 meters (60 feet)). Requirements for materials
and procedures for special or unusual design will be added as necessary for
specific projects. Quantity and quality of illumination will conform to UFC
3-550-03FA. Standard details will conform to the general requirements of UFC
3-550-03FA, and may be modified to suit project conditions.
Do not use Incandescent lamps, Fluorescent lamps, and Mercury Vapor Lamps for
CCTV area illumination, nor tungsten lamps other than infrared lamps.
Two types of infrared luminaires are currently available: fixtures with special
lamps utilizing optical dichroic mirror coatings that produce only infrared
light, and fixtures that use conventional lamps that pass the light output through
infrared filters. Special lamps have the advantage of operating cooler and
not requiring a cooling fan, thus operating quieter and requiring less maintenance.
The major disadvantages are high lamp replacement cost due to short bulb life
(2000 to 4000 hours) and special lamp design. The 2000 hour lamps produce more
infrared light energy and are preferred over the 4000 hour lamps. Another disadvantage
is the limited variety of wattages available, but this is normally resolved
by fixture placement during site lighting system design. Conventional lamps
utilizing special power supplies and infrared filters have the advantages of
low bulb replacement cost and bulb life ranging from 1700 to 18000 hours. (Note:
Special power supplies reduce current flow to the bulb and allow it to operate
at a lower filament temperature to shift light output more into the near infrared
(NIR) light spectrum and requires less filtering. This has the additional advantage
of extending bulb life.) A variety of bulb sizes are available and no special
bulbs are required. The main disadvantage of using a conventional bulb is the
heat generated utilizing an infrared filter which must be cooled by a cooling
fan. Fans require maintenance and the loss of the fan will destroy the filter.
Filters are expensive.

inscribed at not more than 3 m 10 feet on centers with a continuous metallic backing and a corrosion-resistant
0.0254 mm 1 mil metallic foil core to permit easy location of the duct line, approximately 300 mm 12 inches
below finished grade levels of such lines.
3.10 HANDHOLES
Determine the exact locations after carefully considering the locations of other utilities, grading, and paving.
Secure approval of exact before construction is started.
3.10.1 Construction
Construct handholes as indicated on drawings, including appurtenances, with top, walls, and bottom consisting
of reinforced concrete. Provide monolithic walls and bottom. Provide 21 MPa 3000 psi concreteat 28 days. Precast
concrete handholes having the same strength and inside dimensions as cast-in-place concrete handholes may be
used. In paved areas, make the top of entrance covers flush with the finished surface of the paving. In unpaved
areas, set the top of entrance covers approximately 13 mm 1/2 inch above the finished grade. Where finished
grades are in cut areas, install unmortared brick between the top of handhole and entrance frame to temporarily
elevate the entrance cover to existing grade level. Where duct lines enter walls, the sections of duct may be
cast in the concrete or may enter the wall through a suitable opening. Caulk the openings around entering duct
lines tight with lead wool or other approved material.
3.10.2 Appurtenances
Provide the following appurtenances for each handhole.

into the earth before the floor is poured; with approximately 100 mm 4 inches of the ground rod extending above
the floor after pouring. When precast concrete units are used, the top of the ground rod may be below the floor;
bring a No. 1/0 AWG copper ground conductor inside through a watertight sleeve in the wall.
3.11 LIGHTING
NOTE: Following a power outage, a minimum of 10.8 lux (1 foot candle) at grade
within 30 seconds is required. Requirement may be met by including dual re-strike
element lamps for instant re-strike, using incandescent fixtures for backup
lighting or by 5 minute UPS to allow standby power to pickup lighting loads.
When the asset being protected justifies the additional cost, interleaving of
power circuits should be considered for additional security and reliability.
When interleaving is used, the loss of any one circuit should not significantly
reduce the visual detection of intruders. Interleaving may also be useful in
reducing the power demand for backup power sources.
