 Time; the current time in this example is 10:00A which represents 10:00 AM
 Date; the current month, day and year in this example is 03 for March, 08 for the 8th day 
of the month and 06 for the year 2006
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.
