What it is

Silent Knight publishes two programming suites. The Honeywell Fire Software Suite (HFSS) is required for the 6000 Series panels (6700, 6808, 6820 and 6820EVS) and includes an importer that converts legacy SKSS files. The older 5660 Silent Knight Software Suite (SKSS) uploads and downloads programming for the 5000 Series panels locally or remotely, and the 5670 Facility Management Software shows event history and detector sensitivity for IntelliKnight panels.
