EQ2100LC LOGIC CONTROLLER
FEATURES
• Programmable logic
• LEDs indicate status conditions
• Alarm, Trouble and Supervisory SPDT relays
• EMI/RFI hardened
DESCRIPTION
The logic controller provides the control function for the
fire detection portion of the Eagle Quantum fire and gas
safety system. It monitors messages from the devices
on the loop that are configured to report to that
controller (up to 120 in combination) and generates the
appropriate output(s) in response to the input
conditions. The logic controller supports ANSI/NFPA 72
Class A, Style 7 communication with the field devices.
The logic controller uses fixed logic to control the
faceplate display and onboard alarm, trouble and
supervisory outputs per ANSI/NFPA 72.
The logic controller also has programmable logic, which
allows it to be customized to perform complex logic
operations including voting and timing. It also
communicates with the output modules located in the
LIOU, controlling system functions such as alarm
signaling, agent release and relay actuation.
The logic controller receives configuration information
through the gateway by means of its serial connection
to the operator interface system.
Faceplate Description
The faceplate has a key switch, two pushbutton
switches, and nine LEDs. See Figure II-2.
KEY SWITCH
The key switch on the front panel of the logic controller
is used to select from four operating modes — Normal,
Acknowledge & Silence Enable, Reset or Isolate. The
key may be removed in the Normal or Isolate position.
NOTE
Always rotate the key switch slowly when
selecting operating modes.
Normal
In the normal mode, the controller’s program is running
and the outputs are enabled.
Acknowledge & Silence Enable
This mode enables the Acknowledge and Silence
pushbuttons.
NOTE
The Acknowledge and Silence pushbuttons are
inhibited when the key switch is in the Normal
position.
Reset
In the reset mode, normal operation is inhibited and a
reset signal is sent to the LIOU and field output devices.
This mode is also used for programming. In the
program mode, normal operation is inhibited. This is
the only mode that allows configuration information to
be downloaded to the logic controller from the gateway.
When the program mode is exited, configuration
information is sent to the LIOU.
NOTE
If the key switch is left in the RESET position for
more than a second or if the logic controller is in
the Program mode, a Trouble condition will be
indicated.
