Siemens FDCIO422 — Cerberus PRO four-input, four-output addressable interface module, part number S54322-F4-A1.
The module monitors dry-contact equipment and switches external equipment from a Siemens addressable loop. Its four inputs and four outputs share one loop address, which the panel controls as separate functions.
- Four inputs taking two independent 2 × 2 Class A or four Class B dry contacts, each set at the panel as Trouble, Alarm, Supervisory or Status
- Four programmable outputs with potential-free latching Form A dry relay contacts
- Built-in ISOtechnology isolation meeting NFPA 72 Class X, up to 252 isolator devices per loop
- 12 to 32 VDC, 1 mA quiescent, 1.92 mA peak; input cable 200 ft (61 m) maximum, 14 to 18 AWG
- 4 × 4.7 × 1.2 in., 1 lb; UL and ULC listed, FM, CSFM and NYCFD approved
- AC relay ratings apply only from Engineering State 10; Class X needs ES 30 or higher
It ships with a white front plate, four end-of-line devices and three wiring separators, but no back box: it mounts in one electrical box, ordered separately. Keep apart FDCIO422-EOL (S54312-F7-A1), the end-of-line resistor, and TB-EOL (S54322-F4-A2), the terminal.
