Simplex 565-486 — 4100 power-limited expansion supply board assembly.
Johnson Controls Fire Protection catalogs this part as ASSY BD PWR LTD EXP SPLY 4100, grouping it with the 4100 power supply boards rather than with the communication or annunciator daughter cards. Beyond that catalog line we can find no Simplex publication that names it: it is absent from the 4100/4100+/UT parts list, the 4100U list and the 4100ES list. We therefore will not state a feature number, an installation sheet number or any electrical rating for it. If you need that detail, read it from the board you are replacing.
- Manufacturer catalog description: assembly board, power limited expansion supply, 4100
- 565-series numbers are Simplex PC board assemblies used across the 4100, 4020 and 4005 families
Adjacent numbers are easy to transpose: 565-079 and 565-028 are 4100 8-amp power supply boards, 565-560 is the 4100 power supply control assembly, and 565-217 is the 4100 Class A RUI board.
