The Advanced Damper Interface is a loop driven device that utilises the Apollo protocol. The device is a fully monitored interface providing confirmation of the damper open and closed positions. For use with dampers that are normally held open. Fail-safe operation only applicable to electrically opened & mechanically closed dampers. Features Damper motor drive and limit switch monitoring integrated into a single unit Dual limit switch inputs for confirmation of damper-fully-open, and damper-fully-closed positions Selectable monitoring on switch inputs to prevent short circuits in the wiring from giving false position readings Fail-safe options in case of data errors in the communications loop
