Fire Protection System Printed Circuit Board
The fire protection system printed circuit board (PCBCORE) is a microprocessor-based controller that
provides all the necessary monitoring, timing, and supervision functions required for the reliable operation
of the fire system. Under normal conditions, the “Fire System Activated” light is flashing one brief flash
every 3 seconds, indicating the system is armed and ready. If a fault is detected anywhere in the system,
an audible alarm will periodically sound, and the “Fire System Activated” light will flash a fault code to
indicate the fault that was detected. This fault code consists of a series of flashes followed by a pause.
Simply count the number of flashes between the pauses and refer to the chart below to find the cause of
the fault. Any fault is extremely important and must be corrected and rectified immediately to ensure proper
operation of the fire system.
The connections for building fire panels are located at AL1 and AL2 as dry contacts.
