Sensus AMR-960 Installation Instructions

Sensus Tamper Detect Module

Introduction

The Tamper Detect Module was designed for use with the Sensus
PhonRead system Meter Interface Unit (MIU) to indicate that pos-
sible tampering had occurred at the meter location. The "latch"
feature of the module immediately locks into a tamper detect posi-
tion until reset at the location by authorized utility personnel. The
Tamper Detect Module
has four colored wires,
R=Red, B=Black,
G=Green, and Y=Yel-
low. These will be used
to install the Tamper
Detect Module to the
MIU.
The following Tamper
Detect Module installa-
tion instructions provide
for the minimum require-
ments for a successful
installation. This installa-
tion instruction document is only for installation of the Tamper
Detect Module. For instructions on installing other AMR devices,
please request and refer to the individual installation instructions
for those devices.

Installation Instructions
1. Based upon the MIU installation instructions, the following
recommended installation guidelines should be considered for
an actual MIU installation:
a. Placement which is accessible to both utility meter and
intended customer's telephone line access – and the tele-
phone line is working
b. Recommend inside installation (outside permitted) away
from excessive amounts of heat and moisture. (Pit installa-
tions not recommended.)
c. Consider convenience of homeowner
d. Room for installation and future access
e. Consideration for optional TouchRead TouchPad installation
if being used
Installation Instructions
2. Install MIU at selected location and wire to encoder and
phone line according to MIU installation instructions. (Sensus
installation bulletin AMR-971R1)
3. It is recommended that the Tamper Detect Module be adhered
to the electronics cover plate inside the PhonRead MIU. This
can be done by removing the backing of the double stick
adhesive on the back of the Tamper Detect Module and press-
ing firmly onto the MIU electronics cover plate. Be sure to
mount module on the cover plate close enough so that the red
(R), green (G), and black (B) wires coming from the module
can be connected to the proper MIU port. The proper port is
the one that will be programmed by the MIU Programmer for
use with "Tamper Module." This is usually Port 2 of the MIU.

4. Next, connect the wires (RED, GREEN, BLACK) from the
Tamper Detect Module) to the appropriate port of the MIU.
Prior to connecting the wires to the terminals of the MIU, the
wire jacket should be stripped approximately 1/4" at end,
exposing bare wire for each of the colored wires. Be sure to
match the wire colors from the Tamper Detect Module to the
proper terminals of the MIU port – RED to "R", GREEN to "G",
and BLACK to "B". Insert bare wire end into appropriate wire
location and tighten terminal screw to secure wire connection
to the terminal block. Check each connection by pulling wire
gently. See diagram B.
