OS3 Control Panel

OS3 is a modular smoke-control and environmental-ventilation system that is scalable for building safety applications. The system consists of a central coordination module, or “coordinator,” and can handle between 1 and 16 zones, with larger systems handled by networking multiple coordinators together.

The coordinator handles both power and data communication network tasks, constantly monitoring both primary (mains) and secondary (battery) power sources. The system’s intelligent power management capability allows it to constantly evaluate system demand in real time, enabling Manual Control Points (MCPs) to control the operation of Automatic Opening Ventilators (AOVs) as needed.

The OS3 system is fully compatible with Building Management Systems (BMS) and is an economical solution for stairwell ventilation.
