The Simplex 562-320F Panel Card Board Assembly Unit is a panel card board assembly for the Simplex 2120 fire alarm system, identified by the part numbers 562-320F and 562-320-F. This discrete card assembly is described in its product title as a 'Panel Card Board' and is intended for use within the Simplex 2120 panel framework. In vendor listings, the same component appears under both 562-320F and 562-320-F, reflecting alternate spellings used in different documentation and catalogs. Technicians and buyers reference these identifiers to locate the correct spare part for maintenance on older Simplex 2120 installations and to verify compatibility when ordering replacements. The 562-320F/562-320-F designation serves as the primary means of identifying this specific card assembly across procurement records and technical manuals. Because this component is tied to the 2120 panel's modular card architecture, it is commonly catalogued alongside other 2120 panel cards in Simplex spare parts inventories. It is listed in several Simplex catalogs.
