Product Overview

The four (4) input / (4) output interface module (Model FDCIO422) from Siemens

─ Fire Safety is designed to provide the means of interfacing direct shorting devices

on Cerberus PRO Modular | FireFinder XLS/V | FC9-series Cerberus PRO fire-alarm

control panels (FACPs).

Model FDCIO422 provides the “built-in” ISOtechnology feature - intelligent dual

direction isolation meeting NFPA 72 Class X (Style 7) survivability requirements. Up

to 252 isolator devices per loop and in mixed-mode up to 30 devices between

isolator devices (non-isolated devices wired in polarity-insensitive mode).

Additionally, the devices between isolators can either be legacy ‘H’-series or the

more contemporary ‘X’-series devices.

The isolation feature found on the FDCIO422 Intelligent Interface Modules provides

invaluable information as to the location of the wiring fault. When a short occurs,

the panel can identify the fault automatically, and the module recognizes the short

location (in front of or behind the device – simplifying fault condition location in the

application). A true time-saver versus typical troubleshooting methods.

The relays and contact-device inputs for Model FDCIO422 are controlled at the

same address. From the respective Siemens FACP, the relays and input contacts

can be controlled as separate functions. The relay is typically used where control

or shunting of external equipment is required. Four (4) independent input /

output circuits are acceptable on one (1) Model FDCIO422 module.

Normally Open (N.O) or Normally Closed (N.C) dry contacts are monitored by one

(1) 4-Input / 4-Output module, (Model FDCIO422).
