Direct answer

A fire alarm panel beeps and shows a fault to alert you to a problem such as a power or battery fault, a detector or circuit fault, or a system event that needs attention. Read the fault shown on the panel display, silence the internal buzzer if appropriate, and record the fault. Do not simply reset or silence a panel repeatedly without identifying the cause; if the fault persists or you are unsure, contact your fire alarm service provider. Refer to the manual for your specific panel for the exact fault indications and procedures.
