Codesec IO404 Addressable 4 in 1 Input/Output Module

The Codesec IO404 is an addressable 4-in-1 input/output module designed to provide 4 independent inputs and 4 relay outputs within a single unit for fire alarm systems. Communicating directly on the addressable fire loop, this multi-channel module monitors external signals from devices like flow switches and damper positioners while simultaneously triggering auxiliary safety equipment such as fire doors, ventilation fans, and elevator control systems. Built with an integral short-circuit isolator to protect the loop from wiring faults and equipped with individual LED indicators for clear status diagnostics, the IO404 combines four input and output channels into a single compact housing to reduce overall system wiring, installation space, and hardware costs.
