b) Provide wet-pipe, intermediate temperature (preference being 212
degrees F) automatic sprinkler heads in the elevator machine room. Provide a
control valve, check valve, and a water flow switch in the branch line
supplying the sprinklers in the elevator machine room. Locate the control
valve, check valve, and water flow switch in an accessible location outside
the elevator machine room. Provide a water flow switch that, when activated,
causes the main power supply to elevators controlled from that elevator
machine room to be automatically disconnected with no time delay.
c) Automatic sprinklers are not required at the top of the elevator
hoistway except where a roped hydraulic or a holeless hydraulic elevator has
been installed, or where a hydraulic elevator's pressurized supply line runs
at points above the first landing level. If automatic sprinklers are
installed at the top of the elevator hoistway, their activation does not
d) Provide a warning light and an audible signal in the cab of each
elevator. Ensure the warning light is a minimum of 3 inches in height and 4
inches in width. Mount the warning light prominently in, above or adjacent to
the car's operating panel. Do not obscure the light by the elevator's
protective pads. Provide a warning light that cannot be read when not
illuminated. When illuminated, the warning light reads: "DANGER! FIRE!"
"EXIT THE ELEVATOR NOW." Provide an audible alarm, such as a bell, buzzer or
electronic tone, that is louder than any other audible signal being used in
the cab. Supply power to both the warning light and the audible warning
device from the elevator's main controller.
e) Activate the warning sign and audible warning device
simultaneously by a 135 degree F, rate-compensated heat detector mounted in
the elevator machine room. Mount the heat detector adjacent to the sprinkler
head, or equidistant between sprinkler heads when there is more than one
sprinkler head in the elevator machine room. Do not connect the heat detector
to the building's fire alarm system.
equipment to limit noise and vibration in accordance to NAVFAC DM-3.10, Noise
and Vibration Control for Mechanical Equipment.
General Requirements. Design in accordance with MIL-HDBK-1004
series, Electrical Engineering. Ensure electrical work not covered by Navy
criteria meets requirements of NFPA 70.
Distribution Panels. Install distribution panels for technical use
in electronic equipment rooms and other spaces containing technical equipment.
