CPU LED Indicators
AC POWER: A green LED that indicates the presence of normal AC power.
This LED is turned off when the AC line voltage falls below normal.
SYSTEM ALARM: A red LED that indicates an alarm condition. This LED
initially flashes during alarm (the CPU will also sound a continuous audible
tone). Silencing or acknowledging the alarm(s) turns the audible tone off and
causes the LED to illuminate steadily. Subsequent alarms will resound the
audible tone and flash their LEDs. Alarm signals latch until the control panel
is reset.
SUPERVISORY SIGNAL A yellow LED that indicates activation of a circuit
programmed to monitor supervisory devices.
SYSTEM TROUBLE: Indicates the presence of a trouble condition in the
system.
ANNUNCIATOR OR MODULE TROUBLE: Indicates a trouble in a module
in the control unit or in a remote annunciator.
AC/BATT/GND FAULT: Indicates 1) that a power supply is not functioning
correctly, 2) AC line voltage is below normal, 3) improper battery voltage, or
4) that a ground fault exists. Additional information is displayed on internal
LEDs located on power supply assemblies.
SIGNAL SILENCE: Indicates that an output circuit is silenced. Indication will
remain until the reset switch is depressed.
DISABLED CIRCUITS: Indicates that a circuit(s) within the system has been
manually disabled.
CPU Control Switches
ACKNOWLEDGE (SILENCE TONE): Depressing Acknowledge turns the
audible tone off and switches LED operation from flashing to steady. A
subsequent trouble or alarm will resound the audible tone and flash appro-
priate LEDs.
SIGNAL SILENCE: Returns all silenceable outputs, which were automatically activated by the alarm condition,
to their non-alarm state. A subsequent alarm can reactivate alarm outputs.
SYSTEM RESET: The System Reset Switch will reset the system provided that the alarm condition is clear.
Holding this switch depressed will sequentially light (lamp test) all LEDs.
LAMP TEST: The Lamp Test Switch illuminates all the LEDs in the system for as long as the switch is held down.
This switch can also be used to disable or enable individual circuits.
Note:
The CPU produces a pulsed tone for troubles, disabled outputs, and supervisory conditions. A continuous tone
is generated for alarms.
