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 to
the Device Loop Card (Model DLC); FireFinder
XLS, as
well as the Cerberus PRO fire-alarm control panels (FACPs).
Model FDCIO422, which contains microcomputer-chip
(SureWire) technology and is polarity insensitive, achieves
the state of an ‘intelligent device’ through its highly
advanced method of address programming and
supervision ─ combined with its sophisticated, bi-
directional FACP communication.
The relays and contact device inputs for Model FDCIO422
are controlled at the same address. From the FACP, the
relays and input contacts can be controlled as a separate
function. The relay is typically used where control or
shunting of external equipment is required. Four (4)
independent in/out circuits are permissible on one (1)
Model FDC
IO422 module.
Model FDCIO422 is designed to monitor Normally Open
(N.O) or Normally Closed (N.C) dry contacts. Each
interface module reports the status of the (N.O) or (N.C)
to the FACP.
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.
Input lines can be
supervised for open, short and ground-fault conditions
(depending on end-of-line [EOL] termination resistor and
class configuration).
Inputs can be independently configured, via the FACP, for
Alarm, Trouble, Supervisory or Status zones.
Model FDCIO422 has four (4) programmable outputs with
four (4) potential free-latching-type ‘Form A’ (dry) relay
contacts for fire-control installations.
The FACP’s C-NET module provides supervised, power-limited
power supply for Model FDCIO422. 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 of 470 ohms (Ω), as well as three (3) separators to
split power-limited wiring from non-power-limited wiring.
