SECTION 4: JCI100
4-1 INTRODUCTION
The JCI100 (Part No. 1A32364) is a self-
contained gateway device. Its sole
function is to interpret Johnson Controls Inc
(JCI) N2 commands and respond to the
Metasys System with data or to control the
appropriate load point.
There are no user interface components
beyond the ability to control the power and
to reset the controller. The Metasys
Workstation program handles all logical
functions such as grouping, alarms, and
the like.
Figure 4-1.1 labels some components
described in the following SUBSECTIONS.
4-1-1 POWER SUPPLY FUSE
In addition to the protection afforded by the
chassis power supply, the JCI100 also
contains self-protection through the
employment of local fuses of the type
shown. If the Logic fuse is blown the
Power LED will fail to illuminate indicating a
fault. The Breaker fuse is present to
protect the controller from shorts that may
occur between the controller and the circuit
breaker. If the fuse blows the loads will fail
to change state when remotely
commanded.
----Notice----
The Power LED will also fail to
illuminate if “upstream” components
are interrupting electrical flow. For
“no power” reasons check the
Secondary Power Switch, primary
fuse, and supply circuits.
---Caution----
Before preforming any maintenance
on the JCI100 or other control
components, disconnect power at the
Secondary Power Switch. Failure to
do so can cause damage to the
equipment.
4-1-2 FACTORY TEST PORT
This port is used for connecting the
technician’s hand-held programming and
service tool. There is no field service
application for this port.
4-1-3 POWER LED
The Power LED remains steadily illuminated
to indicate continuous and sufficient
electrical energy to run the components on
the JCI100.
4-1-4 COMMAND LED
This LED will blink whenever a load is being
commanded to an On or Off state. This
LED can be important in determining if any
action is being taken once programming is
complete.
4-1-5 NETWORK LED
The Network LED will illuminate in
conjunction with received data.
4-1-6 ADDRESS SWITCHES
The address switches are used to set a
unique address for each JCI100 on the
Metasys network. Setting these switches
will be covered later in this document.

4-1-7 SMART BREAKER SELECTION
JUMPER
At the top center of the JCI100 is a jumper
that is used to select the type of Smart
Breaker that is being controlled. Looking at
the jumper there are three pins and a black
jumper that can connect two of the adjacent
pins. If the jumper is across the top two
pins, the JCI100 will be able to control GHBS
& BABR type Smart Breakers. If the jumper
os across the bottom two pins, the JCI100
will be able to control BABR, BABRS, &
GHQRS type Smart Breakers. Please not
that if this jumper is in the incorrect position,
control problems may be experienced.
