System or Point Trouble Event Operation of the Control Panel
NFS-3030 Operating P/N 51344:C 11/4/03 25
How to Respond to a System or Point Trouble
If the control panel indicates a trouble, the operator can do the following:
1. Press the ACKNOWLEDGE
soft key to silence the panel sounder and switch the SYSTEM TROUBLE
LED from flashing to steady—regardless of the number of troubles, alarms, security and
supervisory signals.
The control panel sends an acknowledge message to the History buffer, installed printers and
annunciators.
2. Check the trouble message for an indication of the trouble.
•Refer to Table 2.1 or Table 2.2 below for point and system trouble explanations, if necessary.
•Press the MORE INFORMATION soft key to display the MORE INFORMATION screen and
view additional information on the device and possibly preprogrammed text for
recommended action. ( Refer to Figure 1.7 on page 16 for an example of the this screen and
an explanation of its fields.)
3. Correct the condition causing the trouble. If the trouble clears, the control panel sends a Clear
Trouble message to the History buffer, installed printers and annunciators.
If all troubles clear and no supervisory signals or fire alarms exist, the control panel does the
following:
•Returns to Normal operation (indicated by the “System Normal” message)
•Sends a “System Normal” message to the panel display, History buffer, installed printers and
annunciators
•Restores troubles automatically - even if troubles are not acknowledged
The soft key PROGRAM/ALTER STATUS is also displayed on this screen. A password is required
to enter these menus, which are described in this panel’s programming manual.
