Specifications
Model FDCIO422 is used for the connection of up to two (2) independent,
2 –x–2 `Class A’ or four (4) independent `Class B’ dry and N.O configurable contacts,
and reports the status of either the N.O or N.C. contact to the FACP. Inputs can be
independently configured, via a Cerberus PRO FACP, for the following zones:
`Trouble’ | `Alarm’ | `Supervisory’ | `Status’.
Model FDCIO422 has four (4) programmable outputs with four (4) potential free-
latching `Form A’ (dry) relay contacts for fire-control installations.
Siemens FACP loop technology provides supervised, isolated, power-limited
communication to a Model FDCIO422 interface module. Optional use of “built-in”
ISOtechnology provides true NFPA 72 Class-X SLC protection against short circuit
conditions.
The four (4) input / (4) output interface module provides status indication per LED
for each input / output, plus one (1) LED for general device status. Also included with
Model FDCIO422 are four (4) EOL devices (470 ohms (Ω), as well as three (3)
separators to separate power-limited wiring from non-power-limited wiring.
Separators are delivered in the following sizes:
 4-
11
/16 inch [12 cm.] back box
 4-
11
/16-inch [12 cm.] extension ring
NOTE: Optional 5” [12.7cm.] back boxes are available exclusively via Randl Industries, Inc.
Model FDCIO422 has a multi-color LED that flashes GREEN when operating in `Normal’ (standby) condition; in AMBER if a node
is in a `Trouble’ event, and in RED to indicate a change of event status.
Model FDCIO422 is fitted with screw terminals for connection to an addressable circuit, and is fully compatible on the same
circuits of all Cerberus PRO and FireFinder XLS/V `H’-series detection devices; Cerberus PRO Modular `X’-series devices; `HMS’-
series addressable manual stations, or any other addressable intelligent modules (e.g. – Model HCP or Model HZM).
Interspersing `X’ & `H’-series devices on the same loop is mostly permitted, but there are exceptions: Models HLIM (isolation
module) and SBGA-34 (audible base) cannot be used with `X’ devices on the same loop.
Field-Device Programmer / Test Unit
Each Model FDCIO422 interface module is compatible with the Siemens field-device programmer / test unit (Model DPU), which
is a compact, portable and menu-driven accessory for electronically programming and testing Model FDCIO422 promptly and
reliably.
Model DPU eliminates the need for cumbersome, unreliable mechanical programming methods (e.g. – dials and rotary
switches), and reduces installation and service costs by electronically programming and testing the detector prior to
installation, via the microcomputer-chip, non-volatile memory found in each Model FDCIO422 interface module.
For proper operation of Model DPU, the technician selects the accessory’s program mode, and enters the desired address. In
turn, Model DPU automatically sets and verifies the address, as well as tests the Model FDCIO422 module.
When in the `test’ mode, Model DPU will perform a series of diagnostic tests without altering the address or other stored data,
allowing technicians to determine if the detector is operating properly.
Each field-device programmer / test unit operates on AC power or rechargeable batteries, providing flexibility and convenience
in the programming / testing of fire-safety equipment from practically any location.
