IMPORTANT:
READ THIS GUIDE PRIOR TO INSTALLING SATELLITE STATIONS.
IMPORTANT WIRE SIZING INFORMATION AND MAXIMUM DISTANCES BETWEEN
SATELLITE STATIONS AND THE SYSTEM PROCESSING CENTER ARE IN THIS DOCUMENT.
1. LOCATION SELECTION
1.1 - The IAQ Enforcer system is a combination of a single
System Processing Center [SPC] and one or more remote
satellite sensing stations. Each satellite sensing station has a
designated location which is identified in Factory Assigned
Settings chart found in the pocket located inside the cover of
the SPC panel.
1.2 - Satellite stations can be "daisy chained" with a single, 3
conductor cable (shielding not required). To determine the
location of the the SPC, the maximum wire distances for each
"daisy chain" must be determined. If the preferred location for
the SPC is within the maximum wire distance, the panel can
be mounted in the chosen location. If the preferred location of
the SPC is not within the maximum wire distance, another
panel location must be selected, a larger wire gage must be
chosen, or the satellites must be wired individually or on a
smaller "chain". The four terminal blocks labeled Ports A, B,
C, and D, are provided to simplify wiring connections.
Satellites can be wired to any port location in the SPC panel.
1.3 - If the total wire distance for each port from the SPC to
the last satellite station is 16 feet or less with 18 gauge wire,
skip to section 2.
1.4 - To determine the maximum distance for any chain,
determine the number of electronics panels and the total
number of sensors for all of the panels you wish to run on a
single "chain". The maximum distance is based on the total
number of satellite station electronics panels and the total
number of sensors on a given "daisy chain". Use table 1.1
(next page) to determine the maximum wire length of 18
gauge, 3 conductor wire, by locating the intersection of the
column from the number of electronics panels (the top row of
table 1.1) with the row of the total number of sensors (the first
column of table 1.1).
Example: You wish to run 4 electronics panels with a total of 8
sensors on a single 3 conductor wire. By using table 1.1 data,
you determine that you can run up to 90 feet of 18 gauge wire
from the panel to the satellite stations. You wish to locate the
SPC panel a total of 60 feet (actual wire run) from the last
satellite station on the chain. Your location for the panel is
acceptable for a single "chain". Check the remaining "daisy
chain" runs, if applicable.
1.5 - Contact EBTRON for other gauge wire charts if required
or for further assistance at 1-800-232-8766.
2. PHYSICAL INSTALLATION
2.1 - The SPC is intended for indoor mounting only.
Locate the panel in a secure, dry environment.
2.2 - Once a location is selected, mounting of the SPC is very
simple. The panel is hung at five mounting points, inside the
panel, as illustrated in figure 2.1. Do not drill any additional

holes in the panel since metal shavings could damage the
electronics and VOID factory warranty.
3. ELECTRICAL CONNECTIONS
3.1 - Refer to the Factory Assigned Settings chart to determine
the location of the satellite stations. Each flow station is
clearly tagged with the unit serial number. The SPC diagnostic
will check that the satellite stations are wired as indicated on
the chart, therefore, proper wiring is essential for system
operation.
3.2 - Multiple satellite stations can be wired on a single, "daisy
chained", 3 conductor cable (shielding not required). "Daisy
chaining" is not required but generally simplifies wiring. If
"daisy chaining" is not used, the total wire length of each run
must not exceed that calculated in section 2.
3.3 - Follow the wiring diagram (figure 3.1) for making the
connections from the satellites to the IAQ SPC panel.
POWER MUST BE OFF TO THE IAQ ENFORCER SPC
PANEL. The power may be switched off at the main power
switch located on the IAQ Enforcer panel electronics, just
below the terminal blocks. All wiring inside of the IAQ Enforcer
Panel should be routed neatly inside the provided wire way
trough.
3.4 - Follow the appropriate instructions for the satellite
stations to be installed (packed individually with each station).
3.5 - Output signals are sourced from the analog output cards
located on the right side of the SPC panel. Refer to the
Factory Assigned Settings chart to determine the source and
output signal of each card. WITH THE POWER TO THE SPC
PANEL OFF, remove one card at a time to connect the signal
wires and place it back in the same slot. THE ANALOG
OUTPUT CARDS MUST BE PLACED BACK IN THEIR
