Use of a licensed commercial electrician for 4500
Series mounting and electrical installation is
required. Raintight or wet location (rigid) conduit
and hubs must be used.
The KNOX-VAULT will need to be disassembled for
mounting. Once KNOX-VAULT has been properly
mounted to wall, re-assemble unit in reverse order
being sure that electrical for both the shutdown
switch and tamper switch have been properly
installed and tested.
Tamper switch leads and field wiring conductors
must be routed separately unless they are both
insulated for the maximum voltage involved in
either circuit.
lock mechanism cover removed or lockout will result.
The large plastic washers holding this cover are special
and must not be changed to another type.
IMPORTANT: When mounting of the KNOX-VAULT is complete,
contact your local fire department to inform them the vault is
ready for lock up.

Door Removal and Adjustment
If door must be removed, remove only the top and bottom hinge
pin screws. Do NOT remove the three hinge bracket screws as
these are factory set for proper door alignment. When replacing
the door, adjust hinge pin screws loose enough so that door
swings freely. Thread locker (LOCTITE®) must be used on hinge
pin screws.

When the KNOX-VAULT model includes a tamper switch, set the tamper switch aside
until the vault is flush mounted. Wiring should be pulled tight so that attempts to force
the vault out of the wall will break the wire or pull the terminals loose. If installing
the vault on a thin or hollow wall, use a solid backing (1-1/8 plywood or 3/8” steel
plate fastened to solid studs on both sides) for secure mounting. Mounting to solid
studs or steel support is always required. Alarm wiring/testing should be performed

Recess models are designed for flush mounting. Do NOT mount face down from ceiling
Wall
or overhang area. Units can be adapted to fit a variety of solid walls or in a concrete
wall. Due to it’s depth, there is NO RECESSED MOUNTING KIT available for the 4500

Stud Wall
When recess mounting to a stud wall, the interior wall must be reinforced across two
studs using thick plywood and steel backplate.
RECESS MOUNTING
TO A STUD WALL
If installing on a thin or hollow wall, use a solid backing (ex: 1/4” steel
plate) to properly reinforce for secure mounting. Mounting to solid studs
or steel support is required. Alarm wiring/testing should be performed
by a qualified alarm installer.
Surface models are designed for mounting on a flat wall. Do NOT
mount face down from ceiling or overhang area. When the KNOXVAULT model includes tamper switches, set the tamper switches aside
until the vault is mounted on the wall. Check to see that the “vault
to wall” tamper plunger is properly depressed. If switch plunger
does NOT properly depress, adjust the screw on the plunger for the
proper length.
The 4500 Series Vault is 7-1/4” deep and weighs 31 lbs. When surface
mounting to a stud wall, the interior wall must be reinforced across
two studs using thick plywood and a steel backup plate.
