Active Supervisory Signal Mode of Operation
3.7.2 How to Respond to an Active Supervisory
If a Latching Supervisory Type Code Displays
Some Supervisory Type Codes latch the control panel (Refer to Table 3.4 for a list of these type
codes). To return the control panel to normal operation, you must correct the condition causing the
supervisory condition, then reset the control panel. Take the following action:
NOTE: If a fire alarm exists, and there are silenced alarms (the
lighted), a Supervisory alarm will resound the panel sounder.
1. Press the
SUPERVISORY
supervisory signals. The control panel sends a Supervisory message to the remote
annunciators, history buffer, installed printers, and CRT-2s.
2. Correct the condition that activated the supervisory point.
3. When you finish correcting the latching supervisory condition, press the
return the control panel to normal operation (indicated by the "System Normal" message). The
control panel sends a "System Normal" message to the LCD display, remote annunciators,
history buffer, installed printers, and CRT-2s.
If Non-latching Type Code Displays
Some Supervisory Type Codes do not latch the control panel. (Refer to Table 3.4 for a list of these
type codes). The control panel automatically returns to normal operation, when you correct the con-
dition that activates the supervisory point. If the control panel indicates a non-latching supervisory
point, take the following action:
NOTE: If a fire alarm exists, and there are silenced alarms (the
lighted), a Supervisory alarm will resound the panel sounder.
1. Press the
SUPERVISORY
supervisory signals. The control panel sends a Supervisory message to the remote
annunciators, history buffer, installed printers, and CRT-2s.
2. Correct the condition that activated the supervisory point.
3. The control panel automatically returns to normal operation (indicated by the "System
Normal" message) and the control panel sends a "System Normal" message to the LCD
display, remote annunciators, history buffer, installed printers, and CRT-2s.
3.7.3 How to Interpret Supervisory Type Codes
The Type Code that displays in the Supervisory message indicates the function of the point that ini-
tiates the Supervisory. For example, a monitor module with a
monitor module connects to a tamper switch.
