Before Starting
The SentriKey® Lockbox is designed to be mounted directly to a building or other secure structure. The Lockbox has
been certified to Loss Prevention Standard (“LPS”) 1175, A10, B3 and C1 when mounted using the following fixings and
substrates:

Mounting the lockbox using any other mounting fixings or onto weaker wall structures will invalidate the security rating.
It is important that the designated Installer undertakes training with Keynetics and follows this instruction manual for the
installation to retain the awarded LPS certification. Should it be required to mount the lockboxes on other than a
conventional masonry wall, please contact Keynetics to discuss suitability and the possible use of different specification
mounting fixings.
This Installation Manual is a confidential document which is only issued to Keynetics trained and designated Installers.
The purpose of this Manual is to act as a reference manual for trained installers. The document remains the property of

Preparation
Position of Installation
It is recommended that the Lockbox be mounted in a position that makes attacks more difficult to reduce the
leverage an attacker can impart on the lockbox.
Surface
It is important that the mounting location is flat. If not, the pressure exerted by the masonry screws when
tightened will twist the Lockbox frame and may render it inoperable. Do not attempt to mount the lockbox on
any surface that is not flat.
On rendered walls ensure the use of
Mungo MBK-STB 10x100mm masonry screws and nylon plugs
as they will
maintain the LPS1175 A10 & B3 security rating.
Contact Keynetics to discuss suitability and the possible use of different mountings for non-standard masonry
surfaces.
Drilling the Mounting Holes into Brick Substrate
Where possible, all fixings should fasten directly into the central part of a brick.
It is important the mounting holes are not in the mortar between bricks.
The drill holes must be at 90 degrees’ angle to the wall and to the specified depth.
Catch and save the dust from drilling to leave the area neat and tidy and to retain the dust for colouring filler used
to refill holes after de-installation.
