2.3 System or Point Trouble Event
2.3.1 How the Control Panel Indicates a System or Point Trouble
A system or point trouble occurs when the control panel detects an electrical or mechanical fault. The panel
will react differently depending on whether or not there are higher priority unacknowledged events.
When no higher priority unacknowledged events are exist, the control panel:
• Produces a pulsed audible tone (if the piezo is enabled)
• Activates the Trouble relay (TB3)
• Flashes the
• Displays a Type Code that indicates the type of device with a trouble (if a point trouble)
• Displays TROUBLE in the upper left corner of the panel display and, if a point trouble, the
type of trouble and information specific to the device. (A system and a point trouble message
are shown in the figures below)
• Sends a Trouble message to the history buffer, installed printer and annunciators
When an unacknowledged event with a higher priority exists, the control panel retains the
indications of the higher priority event (the message, lit LED, audible tone, etc.) while activating
the Trouble relay, flashing the
history buffer, installed printer and annunciators.
A system trouble message is shown in Figure 2.3, and a point trouble is shown in Figure 2.4. Refer
to "Event Reporting Format" on page 13 for identification of each message field.
