Siemens FDCIO422 Input Module

The Siemens FDCIO422 is a 4-input, 4-output addressable interface module that allows ancillary devices such as sprinkler flow switches, damper contacts, and relay-controlled equipment to be monitored and controlled from the Cerberus PRO signaling line circuit. Each input and output point is individually addressable and reports status directly to the fire alarm control panel, simplifying integration of building system interlocks without dedicating a full detector address to each contact.
