About the 562-856
Motherboard assembly 562-856 used in Simplex 4100 series 8-zone Class B zone modules. Simplex zone module instructions show it in the Class B monitor zone wiring and in the security wiring of the 4100/4120-5004 and 4100-5005 modules. The field wiring of the eight zones connects to its terminal blocks, and the zone daughter card plugs into the connector in its center.
The 4081-9002 EOL harness, not the 378-017 resistor, is required at the last device of each Class B zone.
