Introduction
The Field Interface Unit (FIU) provides the communications hardware link between the SiteProTMcentral computer, the SitePro
compatible field satellite controllers and the SitePro Central Decoder System components. The FIU is available in four configurations to provide various combinations of wireline and radio communication paths. An auxiliary port is provided on all FIU
models for switch-type sensor input.
The FIU enclosure is designed for installation in a climate-controlled environment, next to or near the central computer, with a
maximum separation distance of 50' (15.2 m). Power for the FIU is provided by a 100–240 V a.c./12 V d.c. 50/60 Hz power
supply adaptable to both domestic and international plug receptacles. A lighted On/Off rocker switch located on the front of the
FIU controls power to the unit and is circuit-protected with a 1.5 amp fast-blow fuse. An array of indicator lights on the front
panel is provided for visual confirmation of system communication activity.
The following instructions cover installation of the Field Interface Unit (FIU), Surge Protection Unit (SPU), Duplex Modular Wall
Plate, optional Radio-Link components and optional SitePro Central Decoder System (CDS) components. For Network CDS
system installation, additional detailed installation information is provided with the Network CDS Decoder Interface Unit (DIU).
IMPORTANT: For your safety and equipment protection, please comply with all Caution and Warning statements
within this document. It is the responsibility of the installer to comply with all NEC and/or local electrical codes that
apply to the installation of this equipment. Please refer to page 16 for FCC and CISPR 22 information.
Note:
Some cabling and hardware components are provided for installation of the FIU, Surge Protection Unit (SPU) and
duplex modular wall plate. All other materials; i.e., wire, conduit, grounding conductors, communication cable, radio(s) and
related radio hardware must be purchased separately.
The diagrams on pages 1–5 depict the various FIU model system configurations. See
Figures 1 and 5 for model 2010
(Figure 1 - Satellite, Figure 5 - CDS), FIgure 2 for model 2020, Figure 3 for model 2011 and Figure 4 for model 2021.

Installing the Field Interface Unit,Wall Plate Assembly and Surge Protection Unit
1. Position the Field Interface Unit within 6' (1.8 m) of the PC.
Note: Maximum distance is 50' (15.2 m).
2. Using the serial cable(s) supplied, connect the PC to the FIU as illustrated
in the appropriate configuration diagram
Figure 1–5.
3.
Note: The methods of cable connection will vary depending on the availability of computer COM ports. DO NOT USE P0 FOR CONNECTION. P0
is recommended for an external modem.
4. With the power switch in the Off position, plug the power adapter into the
FIU 12 V d.c. receptacle and the wall socket outlet using the appropriate
AC power cord supplied. Leave the FIU power switch in the Off position
until the installation has been completed.
5. To prevent the power wire from being accidentally pulled out, install the
power wire through the strain relief and tighten securely as shown in
Figure 6.
Note: Regulatory agencies specify that when connecting plug-in equip-
ment, the socket-outlet shall be located near the equipment and shall be
easily accessible.
6. To facilitate installation of the modular wall plate, install a standard duplex junction box to the wall within 5' (1.5 m) of the
FIU. The RJ11 modular cable(s) provided are 6' (1.8 m) in length.
