MIL-HDBK-1027/4A
5.2.8
Electrical. Typically, specific electrical requirements for
training facilities and/or training device(s) are contained in the
manufacturer's technical manual. Applicable MIL-HDBK-1004 series provides
general guidance on electrical engineering. Consult these in conjunction
with the current editions of NFPA 70 and ANSI C2.
a) Classrooms. Locate 120 volt convenience outlets for use of
portable audiovisual equipment. Provide conduit stub-outs with pull wire in
ceiling space for future ceiling mounted audiovisual aids, such as projection
systems. Locate remote control and microphone outlets off-center on front
wall, convenient to the podium. Provide two-way communications from
classrooms to administrative area or security desk, if required by the user.
b) Corridors. A shock hazard exists from convenience outlets in
areas where floor buffers are used. Provide locking type outlets and metal
device covers mounted high above splash zones.
c) Visitor Control. Consider an intercom which includes capacity
to receive calls from rooms where medical emergencies are likely to occur.
d) Maintenance Repair Shop.
Provide GFCI 220 volt service.
See
collateral equipment list.
e) Pool/training. Consider a microphone outlet at the view window
and underwater speakers for instructors to communicate with students. Locate
an switch convenient to the pool deck to sound an alarm in the administration
area for emergencies. Ground all exposed metal used for ladders, handrails
and other deck equipment in accordance with the National Electrical Code.
5.2.8.1
Telecommunications. Provide a structured telecommunications system
including interior and exterior conduits, cabling, pull wire,
telecommunications backboards, and outlets. Provide a telecommunications
outlet for each elevator in the facility. Refer to MIL-HDBK-1012/3 for
interior telecommunications cabling. Locate outlets as directed.
Consider
telephone and communication outlets in maintenance areas and dedicated lines
at devices where networking is anticipated. Accommodate any special user or
government contractor communication requirements which may require intercom
features integrated into the telephone system.
5.2.8.2
Lighting. Provide fluorescent fixtures with battery packs and/or
wall packs for emergency lighting, in lieu of a central system.
a) Classrooms. Lighting controls (dimmers and/or selective lamp
and ballast switching) with discrete circuits for the front of the room,
allow for effective visual use of television monitors, projectors, view
graphs, etc.
Use spectrum ranges appropriate for classroom settings.
Emergency lighting is required as a safety precaution for operation of
equipment during power failures.
b) High Bay. In high bay areas, include provisions for
maintenance access to fixtures for repair and re-lamping, especially over the
pool area. Consider wall mounted lighting located at a level that allows
servicing by means of a 6 feet stepladder.
