Siemens FDCIO422 Addressable Input / Output Module

The Siemens FDCIO422 Addressable Input / Output Module is used for the connection of up to 2 independent Class A or 4 independent Class B dry N/O configurable contacts. Input lines can be supervised for open, short and ground fault conditions (depending on EOL termination resistor and class configuration). Inputs can be independently configured via the fire control panel for alarm, trouble, status or supervisory zones. The FDCIO422 has 4 programmable outputs with 4 potential-free latching type form A relay contacts for fire control installations. Mounts directly into a 4 11/16-inch square box or 5-inch square box. An additional extension ring can be mounted on the 4 11/16-inch square box with two screws.
