5. All that remains to be connected is the YELLOW “Y”wire. This
wire is used to create a continuity loop to where the tamper
detect is desired to be installed. This is usually a meter location.
If the MIU is located near the meter installation, a single plastic
coated seal wire can be used to create the continuity loop with
the Tamper Detect Module.
If the MIU is a further distance away from the meter, a separate
wire connection is recommended. This separate wire connec-
tion can be part of a multi-conductor wire that is used to con-
nect the meter encoder to the MIU or a separate two-conductor
wire that can be installed to the meter location. In either event,
the Tamper Detect Module installation is the same.
For a single wire connection:
a. Connect one end of the single plastic coated seal wire to the
yellow “Y”wire on the Tamper Detect Module. It is recom-
mended that you use a 3M UY-2 gel-cap connector to connect
the wires. The end of the plastic coated seal wire need not
be stripped to use with the gel-cap connector.
b. Run the plastic coated seal wire through the desired tamper
location (i.e., meter connection nut, register seal hole, meter
cap screw, etc.) and back to the MIU.
Note: Be sure not to make a cut in the plastic coat of the seal wire
or you will receive a false tamper indication on the PhonRead
software. See diagram below.
c. Strip off approximately 1/4" of the coating on the seal wire or
connection to the MIU terminal strip. If Port 1 of the MIU has
been programmed for “Tamper Module”connect the seal wire
end to the TP terminal marked 5 on the MIU circuit board; if
Port 2 was programmed for “Tamper Module,”connect the
seal wire end to the TP terminal connection marked 10 on the
MIU circuit board.
d. This completes the tamper loop connection. Proceed to the
Testing section.
For a separate wire (long run) connection:
a. For a long run connection you need a separate length of two-
conductor wire or an extra “pair”of wires in a multi-conductor
length of wire. This long run of wire must run from the MIU to
the tamper detect location.

b. Connect one end of the two-conductor wire or one of the pair
of wires of the multi-conductor wire to the yellow “Y”wire on
the Tamper Detect Module. It is recommended that you use a
3M UY-2 gel-cap connector to connect the wires. The ends of
the wires need not be stripped to use with the gel-cap connec-
tor.
c. At the other end of the long run of wire connect the plastic
coated seal wire to the same color of the two-conductor or
multi-conductor wire that is connected to the Yellow “Y" wire of
the Tamper Detect module. It is recommended that you use a
3M UY-2 gel-cap connector to connect the wires. The ends of
the wires need not be stripped to use with the gel-cap connec-
tor.
d. Run the plastic coated seal wire through the desired tamper
location (i.e., –meter connection nut, register seal hole, meter
cap screw, etc.) and back to the long run of wire.
NOTE: Be sure not to make a cut in the plastic coat of the seal wire
or you will receive a false tamper indication on the PhonRead soft-
ware. See diagram below.
After installing the Tamper Detect Module, the operation of the device
can be tested as follows:
a. Use an Sensus Solid State Interrogator (SSI) that has been
loaded with the MIU programming software module.
b. Connect the SSI to the MIU programming port using the MIU
programming cable. For detailed instructions on using the SSI
to program an MIU, refer to the SSI Programming User’s Man-
ual, literature #AMR-986.
c. You will be using the MIU Commands feature of the SSI to
check the port to which the Tamper Connect Module is
installed. These instructions are located on pages 3-11 to 3-14
of the SSI Programming User’s Manual.
d. At the first view screen of the SSI in MIU programming mode,
press the “Shift”key, then the “Sensus Logo”key. This will
bring up programming options “1-Edit Defaults”and “2-MIU
Commands”. Select “2-MIU Commands”.
