4.3 External VSmart Module Wiring
VSmart modules should have dedicated AC power and two (2)
ground connections for the module and barrier.
1. Pull two (2) AC power wires and one (1) ground wire (14-
AWG minimum) from the circuit breaker to each module;
multiple modules may share same circuit as long as they do
not exceed the circuit breaker rating.
2. Pull one (1) additional ground 12-AWG from panel for I.S.
barrier ground.
NOTE: See Integra 500 Field Wiring Diagram for VSmart Module
wiring.
3. All OPW equipment must share the same phase of AC
power.

4.3.1 VSmart Addressing
VSmart modules must be assigned a unique identification number.
Module numbers must be unique within the Module Group; that is, it
is possible assign the same number to both a VSmart Module and to
an OM4 Module, but it is not possible to assign the same number to
more than one VSmart Module or to more than one OM4 Module. The
module numbers are used when the system is configured. Refer to
the “M1801 SiteSentinel
®
Integra™ Configuration Manual” for details
about system setup.
A small, white rotary switch is located at the top of the
PC board inside each module. The switch has 10
positions, marked “0” to “9.” A small arrow on the switch
points to the current position. Default switch setting is
“1.”
NOTE: Although the switch has 10 settings, only settings 1-8 are
valid. DO NOT set the switch to either “0” or “9” – the module will
NOT be recognized by the system.
Follow these steps to set the Petro-Net™ address:
1. Turn the module power OFF.
2. Use a ¼-inch (6 mm) blade screwdriver to gently
rotate the rotary switch to the desired location.
3. Turn the module power to ON.
CAUTION: Do not change the module number while the module
power is ON.
NOTE: The eight-position DIP switch should remain in the closed
position for normal operation.
