Fire Protection System Printed Circuit Board
The fire protection system printed circuit board (PCBCORE) is a microprocessor-based controller that pro-
vides 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 on. This indicates the system is armed and
active. 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. The HMI, located on
the hood or Electrical Control Package (ECP), will display the fault text to explain where the issue is
located in the system. Refer to “CORE Board Faults” on page 54.
NOTE: CORE Boards with software version 1.68 and prior will use one brief flash every 3-seconds
to indicate there are no faults in the fire system.
When viewing the CORE Board, if a series of flashes followed by a pause exists, there is a fault in the sys-
tem. Count the number of flashes between the pauses and refer to “CORE Board Faults” on page 54.
Any fault is extremely important and must be corrected and rectified immediately to ensure proper opera-
tion of the fire system.
The optional connections for building fire panels are located at AL1 and AL2 as dry contacts.
For remote mounted Ansul Automans, use terminals AU1 and AU2. This will provide a dry contact connec-
tion point to provide power for activating the Ansul Automan.
NOTE: When a CORE board is connected to an ECPM03 board, if a fire condition happens, the
“Last Fire Info” will be stored on the ECPM03 screen. “Last Fire Info” will be available on CASLINK
as well.
