• 1601 W. Deer Valley Road, Phoenix, AZ 85027 • (800) 552-5669 • (623) 687-2300 • Fax (623) 687-2299 • Web: www.knoxbox.com • E-mail: [email protected]1. The Knox-Vault® tamper switch is designed to be connected to an
existing alarm system and should be installed only by a qualied
alarm technician.
2. Position Knox-Vault on wall so wires from alarm panel protrude
into box through hole (A) in back plate. See gures 1, 2 & 3.
3. Bolt Knox-Vault to wall, following directions provided in mounting
instructions
Important: Keep tamper switch hole (B) clear of caulk, debris or
other foreign material, otherwise tamper switch may not operate.
4. Recessed Mount Knox-Vault uses door tamper switch only,
therefore the rear tamper switch is omitted. To install tamper
switch assembly: Align tamper switch mounting holes with threaded
holes in back plate. Insert and tighten two tamper switch mounting
screws provided. (See gures 1 and 2).
Surface Mount Knox-Vault: Align rear tamper switch plunger with
hole (B) in back plate, as shown in gure 1. Check length of plunger
and, if necessary, adjust plunger screw to give proper travel. Check
plunger contact by GENTLY pressing the bracket ush against the
back plate. CAUTION: If the rear tamper switch adjustment screw
protrudes too far, the rear tamper switch will break when bracket
is tightened. Use of an ohm meter is recommended to assure that
switch trips (0 ohms – for red/green wire, open for yellow wire)
when bracket is GENTLY pushed ush against the back plate.
Secure tamper switch to back plate with screws provided.
5. Connect tamper switch wires to building alarm. Alarm wiring must
be pulled back though the Alarm Wire Opening (A) to prevent
interference with the lock mechanism. Green and Red wires must
be secured tightly so that if box is removed, wires will be broken
in the process, thereby causing alarm activation. Yellow wires
should be loosely secured so that if box is removed the wire can
pull out about an inch to allow rear switch to close and cause an
alarm before wires break.
