Your SupraSafe is the latest in Rapid Entry key 
control. To fully utilize it’s built-in security features, 
we recommend that reasonable care be given to the 
location and method of mounting.
The vault is coated with a tough, baked polyurethane 
abuse; however, it is always best to locate the vault 
in an area which is sheltered from excessive moisture 
and possible mechanical damage. 
Important! Contact your local   
department for 
 mounting location 
and instructions.

50 ma. Consult local codes and ordinances prior to 
installations.

Important! When installing the vault, do not 
over-tighten the four mounting bolts as this 
may distort the outside shell of the vault.
4. To secure the vault to a masonry/brick wall, it 
is necessary to use the anchors provided with 
the 5/16 lag bolts mounting kit. Drill a 1/2” hole 
approximately 1-3/4” deep into the masonry/brick 
wall. It is recommended to use a carbide/masonry 
bit to prevent cracking or shattering. Gently pound 
the anchor into the hole with a hammer so that it is

Instructions for SupraSafe 2HSR and 
SupraSafe 2HSR/TS Vaults
The SupraSafe 2HSR and SupraSafe 2HSR/TS vaults 
are designed to be recessed into a wall for attractive 
ush mounting. These units can be adapted to t a 
variety of hollow wall situations or can be installed in 
a sold concrete wall which has been cored to a six 
inch diameter. For concrete or masonry walls in new 
construction, we recommend the use of our Cast-in- 
Place Mounting Kit described below.
With the SupraSafe 2HSR/TS, removal of the tamper 
switch is not necessary during installation. The alarm 
wiring to the tamper switch should be pulled tight 
so that any attempt to force the vault out of the wall 
will break the wire or pull terminals loose. Push-On 
type terminals are supplied for connection to tamper 
switch. Tamper switch can be connected for either 
open or closed circuits.
Cast-in-Place Mounting Kit (P/N: 454000)
The Cast-in-Place Mounting kit is used only with the 
SupraSafe 2HSR and SupraSafe 2HSR/TS vaults. 
The kit contains a shell housing and mounting 
hardware to be cast in place in new masonry or 
concrete construction. After construction is completed, 
the vault mounts inside the recessed shell housing so 
that the small moisture drain hole is on the bottom.

studs within the vault. Do not over-tighten mounting 
nuts as this may distort outside ange. 
3. Slip the chain mounting bracket (attached to the 
chain-lid assembly) over the lower right-hand stud 
prior to installing the bottom washers and nuts in the 
vault. This will permanently attach the lid to the vault.
4. Please contact your re department to install the lid  
once the vault has been installed.

The mounting kit may be fastened to the inside wall 
of a concrete form or set in place during construction 
of a masonry wall. Wiring conduit may be connected 
through one of several knockout holes in shell housing. 
The orientation of the mounting kit requires that the 
rebar on the backplate be horizontal. Mount the 
housing shell to the backplate so that the tamper switch 
adjustment screw is on the left side of the housing.
Important! Care should be taken to insure that the 
front of the shell housing, including the cover plate and 
screw heads, is ush with nish wall. Shell housing 
should be plumbed with a level. Leave cover and 
screws in place until vault is ready to be mounted inside.
Four mounting studs are provided for securing the 
vault and chain-lid assembly within the housing shell.
1. Place vault in housing shell of mounting kit so 
that the vault’s small moisture drain hole is on the 
bottom. Align the tamper switch of the vault with 
the tamper switch adjustment screw of the housing 
shell. The tamper switch adjustment screw has a 
slotted head to adjust for proper switch operation.
2. Install washers and nuts onto the two top mounting
