If Non-latching Type Code Displays
Some Supervisory Type Codes do not latch the control panel. (Refer to Table 6 for a list of these type
codes). The control panel automatically returns to normal operation, when you correct the condition 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
SIGNALS
SILENCED
LED is lighted), a Supervisory alarm
will resound the panel sounder.
1. Press the
ACKNOWLEDGE
/
SCROLL DISPLAY
key to silence the panel sounder and switch the
SUPERVISORY
LED from flashing to steady—regardless of the number of troubles, alarms, and
supervisory signals. The control panel sends a Supervisory message to the History buffer and
installed printers, terminal mode LCD-80s, 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, History
buffer and installed printers, terminal mode LCD-80s, and CRT-2s.
How to Interpret Supervisory Type Codes
The Type Code that displays in the Supervisory message indicates the function of the point that initiates
the Supervisory. For example, a monitor module with a
TAMPER
Type Code means that the monitor
module connects to a tamper switch.
