vault. Refer to AR 190-11 for security criteria. Electrical power is to
be provided through a nonfused 30 amp disconnect switch, located in
the arms vault, to a lockable 30 amp disconnect switch fused for 20
amps, connected ahead of the main in the electrical room. A 19 mm
(3/4 in) rigid conduit will be provided from the telephone terminal
board to a junction box located in the arms vault and a 19 mm (3/4
in) rigid conduit from the arms vault junction box to a recessed
junction box mounted on the building exterior.
4.2.11.5 Provide a 110 volt outlet and a 50 mm (2 in) diameter floor
drain for the dehumidifier. These should be located adjacent to each
other and outside of the caged areas.
4.2.11.6 Battery backup, fluorescent fixtures to illuminate the vault
door should be provided over the vault door if it opens into a corridor
or other space other than the armorer's room, such as the assembly
hall of unit storage. These lights will be connected directly to the panel
board. If the vault door opens into the armorer's room, this egress
lighting should instead be provided outside the armorer's room door.
4.2.11.7 Coordinate lighting and caging layout to allow caging walls to
extend to ceiling. In laying out arms vaults, use a 1525 mm (5 ft)
module for width to allow a 915 mm (3 ft) aisle between 260 mm
(10-1/4 in) wide rifle racks. Use a 915 mm (3 ft) module for length to
allow for 915 mm (36 in) rifle racks.
4.2.11.8 Gun racks and containers are Government-supplied and
installed. Wire caging on the modules described above is to be
provided in vaults serving more than one military unit if requested.
Class V containers (safes) are approved for use instead of small arms
storage racks and arms rooms where small quantities of weapons,
central firing components and related ammunition are stored. Specific
cabinets authorized for use are listed in AR 190-11.
fire extinguisher should be located adjacent to the motion detection
control box, both of which should be outside caged areas.
4.2.11.10 Anchorments for securing weapons in the racks should be
provided in the floor, and must be coordinated with floor construction
and reinforcing. Floor anchorments should not protrude from floor,
and must be coordinated with slab thickness and reinforcing; consider
using airport mooring eyes, as manufactured by Neenah Foundry and
others.
