Cooper CIO351S 3 Channel Input Output Unit

Cooper CIO351S is a 3-channel Input/Output unit manufactured by Cooper Eaton, designed to integrate seamlessly with the Cooper range of fire detection control panels. The module supports up to 3 separate inputs and 3 separate outputs, providing a straightforward and reliable interface between the fire detection system and third-party equipment.

The CIO351S model features reset on alarm silencing and a soft addressing system, which removes the need for hardware addressing: only one address is required at the control panel to monitor and control the entire unit, significantly reducing installation complexity and equipment costs. The module incorporates an integral short circuit isolator and provides continuous monitoring of inputs for open and short circuit conditions. Thanks to its plug and play design, installation is quick and straightforward with no additional hardware configuration required. The CIO351S is the ideal solution for interfacing with nurse call systems, access control systems, and other equipment compatible with fire detection installations.
