Silent Knight 6855 — remote LCD fire annunciator for the Silent Knight 6000-series addressable panels.
The 6855 mirrors the control panel display at a remote location so responders can read status and operate the panel without walking back to the FACP. It connects on the panel SBUS, takes an ID from DIP switches on its back, and is then picked up by JumpStart auto-programming — the usual answer when the panel sits in a back-of-house room.

Check the panel model first. The 5860 is a similar 4 × 20 unit but belongs to the IntelliKnight 5700 / 5808 / 5820XL family. A 6820 accepts either; the 6855 lists the 6700, 6808, 6820 and 6820EVS only.
