II–6
Isolate
In the isolate mode, normal operation continues while
the logic controller sends an isolate command to all the
agent release outputs in the LIOU. The Isolate LED
turns on in a steady state if all release outputs are
isolated. The LED is off when none of the outputs are
isolated and blinks if only some of the outputs are
isolated.
NOTE
User logic is required to isolate LON based agent
release modules.
PUSHBUTTON SWITCHES
Acknowledge
Pressing the acknowledge pushbutton with
Acknowledge/Silence enabled acknowledges the
current status condition(s) and turns off the internal
buzzer.
Silence
Pressing the silence pushbutton silences the selected
signaling outputs in the LIOU. (The specific LIOU
outputs that are affected by the silence button are
selected at the time of system configuration.)
NOTE
Signaling devices connected to LON based Signal
Audible Modules must be silenced via user logic.
LEDS
Nine faceplate LEDs are provided for indicating system
status conditions.
POWER (Green)
Indicates that power is applied to the device.
ALARM (Red)
Indicates that the Fire Alarm relay is actuated.
TROUBLE (Yellow)
Illuminated when a trouble condition occurs in the wiring
or devices associated with the fire system. (Trouble
relay is active). All logic controller faults are latching
and must be cleared by resetting with the key switch.
Det-Tronics configuration software should be used to
determine the specific problem.
POWER FAULT (Yellow)
Indicates that a power supply fault has been detected.
This could involve any of the following:
— ground fault
— low or missing AC input voltage
— 24 vdc power supply
— battery related fault
— power supply monitor
— IDCGF.
SUPERVISORY (Yellow)
Follows the status of the Supervisory relay.
ACKNOWLEDGE (Yellow)
Illuminated when the acknowledge switch is pressed
and remains lit until the unit is reset.
SILENCE (Yellow)
Illuminated when the silence switch is pressed and
remains on until the unit is reset.
PROGRAM (Yellow)
Indicates that the logic controller is in the
Reset/Program mode.
ISOLATE (Yellow)
Indicates that the logic controller is in the Isolate mode.
Relays
The Logic Controller has three relay outputs,
responding to the following status conditions:
— Fire alarm (Activated when any device that is
configured as a fire alarm input is active. This
includes all flame detectors and IDCs that are
configured as alarm type inputs.)
— Supervisory (Activated when a supervisory fault
occurs at any LON device that is configured to
report to the Logic Controller as a supervisory
input.)
— Trouble (Normally energized). Activated when any
of the following occurs:
LIOU communication, wiring or other fault
AC input failure
Battery fault
Power supply fault
Invalid configuration
LON fault
LON device communication fault
Gateway LON fault
RAM fault.
