4.3.1 How to Operate the Panel in Normal Operation
“Normal operation” refers to a control panel that is operating normally—no alarms or
troubles in the system and the “All Systems Normal” message appears in the LCD
display. Figure 100 shows a typical screen that appears with the control panel in normal
operation:
Figure 100 Typical Display Message During Normal Operation
The control panel does the following functions at regular intervals when in normal
operation:
• Polls all devices connected to the SLC and the four NAC/Panel Circuits for valid
replies, alarms, supervisory, and trouble signals
• Checks for power supply troubles and batteries every 10 seconds
• Sends a supervisory query on the LCD-80 interface and verifies proper response
• Refreshes the LCD display and Terminal Mode LCD-80 display and updates time
• Scans the programming keypad for System Reset or Enter
• Auto tests detectors
• Tests system memory
4.3.2 How to Operate a Panel with a Trouble Condition
What is a Trouble Condition?
A control panel indicates a trouble condition when a trouble—for example, a short
circuit or ground fault—exists in the fire alarm system. If all troubles clear and no
supervisory or fire alarms exist in the system, the control panel returns to a normal
operation, and sends an “All Systems Normal” message to the LCD display, LCD-80,
History buffer, and printer. This trouble restore occurs even if the troubles were never
acknowledged (auto restore).
During a Trouble operation the control panel does the following:
