The Simplex 562-909 is a replacement CPU board assembly for legacy Simplex 4002 series fire alarm control panels. The 562-909 serves as the central processing and communications board for the 4002 platform, handling point scanning, event processing, and panel-to-peripheral communications. Replacing a failed CPU board restores full panel function without requiring a complete panel replacement — a cost-effective option when the enclosure, power supply, and NAC circuitry remain serviceable.
The manufacturer-designated replacement assembly for the 562-909 is the 565-180. When the 562-909 is not available as new stock, the 565-180 should be specified as the direct replacement. Both serve the same 4002 platform CPU function; verify compatibility with your specific panel revision and firmware level before installing.

When sourcing replacement boards for legacy panels, request documentation of any firmware revision included. The 562-909 or its replacement 565-180 may require firmware matching to the panel's existing database backup to restore programming correctly. Always back up the panel database before replacing the CPU board.
