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
flush mounting. These units can be adapted to fit 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.
Installation
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 flush with finish 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
studs within the vault. Do not over-tighten mounting
nuts as this may distort outside flange.
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 fire department to install the lid
once the vault has been installed.
