MIL-HDBK-1024/1
4.4.3
Ceilings.
Provide acoustical tile ceilings.
Refer to par. 2.3.8.9.
Windows.
Do not provide windows.
4.4.4
4.5
Mechanical Requirements. Design mechanical systems to meet the
criteria in pars. 2.4, 4.5.1, and 4.5.2. Ensure mechanical systems do not
interfere with radar transmissions.
4.5.1
Provide a minimum temperature of 70 degrees F.
4.5.2
Air Conditioning. Provide two separate air conditioning systems,
each capable of handling the entire load independently. One unit will
function as a secondary backup unit should the primary unit fail. Provide the
following:
a)
Separate thermostat controls for each unit.
b)
Interlocked primary and secondary units to prevent simultaneous
operation.
4.6
Electrical Requirements. To avoid potential interference with radar
transmissions locate power, communications, and control cables underground
within 1,500 feet from the antenna site. Ensure electrical systems do not
interfere with radar transmissions.
4.6.1
Emergency Electrical Power. Provide an emergency generator with
automatic starting and switching capability as described in par. 2.5.7.
Provide emergency power to the entire radar facility.
4.6.2
Uninterrupted Power Supply (UPS). Provide non-redundant UPS in
accordance with par. 2.5.8. Use the anticipated load to determine the size of
the UPS.
4.7
Security. Air surveillance radar facilities are normally located
within restricted areas which would typically meet the minimum security
measures for external security. When the facility is located within a
restricted area of a lower level of security or is located remote and outside
of an established restricted area, provide additional measures to meet the
minimum security requirements for the level of security assigned to the
facility. The level of security and the designer's responsibility for
particular security elements will be designated in the IDSEP. Refer to par.
2.6.
Additional Design Criteria.
Refer to Section 2 for facility design
4.8
