Simplex 562-799 — Style B termination motherboard with suppression for Simplex 4100, 4100U and 4100ES fire alarm control panels.
In the 4100 family a motherboard is the termination backplane that mounts in a back box bay: plug-in cards seat onto it and field wiring lands on its terminal blocks. Boards chain left to right through P1 and J1 to carry power and communications across the bay. Simplex catalogs this one as Motherboard, Style B (w/Suppression) — the suffix is suppression, not supply.
- Simplex designation: Motherboard, Style B (w/Suppression)
- Style B is the Simplex label that replaced the older Class B
- Mounting motherboard for the Remote Unit Interface (RUI) card in MINIPLEX master controller bays
- Service part across 4100, 4100+/UT, 4100U and 4100ES systems
- Installs with four screws, connector J1 right and header P1 left
This block differs by a single digit. 562-856 is the same Style B board without suppression; 562-823 and 562-733 are the Style D (formerly Class A) boards; 562-727 and 562-858 are the 32-point auxiliary relay 2 A motherboards. Confirm style and suppression before ordering.
