The Simplex 565-556 is a Class A adapter card used with Simplex addressable fire alarm panels. Specifically, it carries the 4005-9806 cross-reference for the Simplex 4005 series.
First, the card plugs into the Simplex panel. Then it reconfigures a signaling loop for Class A wiring instead of Class B.
What the Simplex 565-556 Does
Class A circuits run an extra return conductor back to the panel for redundancy. In addition, that loop lets the panel keep monitoring devices even if a single wire break occurs.
Therefore the 565-556 adapter card is what enables that wiring scheme on the Simplex 4005 platform. As a result, designers can apply Class A where the local code or design spec calls for it.
Where the 565-556 Is Used
You will find the 565-556 on Simplex 4005 series fire alarm panels that need a Class A loop. Furthermore, retrofit projects swapping out an old adapter typically reference the 4005-9806 part number.
