SmartOne® Model AO provides an unpowered, Form-C contact for remote control applications.
The SmartOne® Addressable Relay Output Device (AO) is an addressable output module for control of auxiliary equipment such as air handlers, door release and elevator recall. The AO connects directly to a compatible control unit's signaling line circuit (SLC) and contains a SPDT relay to control auxiliary equipment. All of the electronics are contained in a small high-impact polymer case. This creates a small and durable device for installation.
