4.6 Supervisory Operation
Supervisory operation is similar to alarm operation but with the following differences:
• The piezo sounder pulses ½ second On and ½ second Off
• The Supervisory indicator flashes ½ second On and ½ second Off
• The LCD displays the status label Active Supervisory along with the device name, type,
adjective/noun, associated zones and time/date
• The output circuits programmed as Supervisory NAC are activated
• The supervisory relay is activated
• The alarm relay is not
activated
• Silenced alarms are not resounded
• Timers are not started
• Store event in history buffer
A typical Supervisory event would be displayed as illustrated in the following:
In the preceding example:
U FROZEN SUPRV - indicates zone detector is below approximately 45
o
F
Note that, like alarms, supervisory signals latch (except when programmed for supervisory
autoresettable). Supervisory alarms do not cause resound as do other alarm conditions. Open
circuits in supervisory wiring are processed by the control panel the same way as other trouble
conditions. Refer to "Alarm Operation" on page 88, for a description of the information displayed
on the control panel LCD.
4.7 Disable/Enable Operation
Input zones which are disabled do not cause an alarm or any zone activation. Disabled NACs are
held in the off state. Disabled zones/NACs are treated as if they were in trouble, with the exception
being the LCD status label that will be displayed is DISABL.
Note that disabled Releasing Circuits are treated as supervisory events.
4.8 Waterflow Circuits Operation
If an alarm exists from a zone that is a waterflow non-silenceable type, the Alarm Silence key will
not function.
