Operation of the Control Panel Supervisory Signal Event
2.6 Supervisory Signal Event
2.6.1 How the Control Panel Indicates an Active Supervisory
The system indicates a Supervisory alarm when a monitor module point programmed with a
supervisory Type Code activates. 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 warbling audible tone (if the piezo is enabled)
• Activates the Supervisory relay (TB2) if it has been selected for supervisory
• Flashes the
SUPERVISORY LED (yellow)
• Displays a Type Code that indicates the type of supervisory signal being generated
•Displays
SUPERVISORY in the upper left corner of the panel display along with information
specific to the device
• Sends a Supervisory 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 Supervisory relay if it is selected for supervision, flashing the
SUPERVISORY LED, and sending
a Supervisory message to the history buffer, installed printer and annunciators. If there are silenced
alarms (the
SIGNALS SILENCED LED is lighted), a Supervisory alarm will resound the panel
sounder.
Following is a typical supervisory message that would appear on a panel display:
