SIEMENS FDCIO422 Addressable Input Output Module Instruction Manual

SIEMENS FDCIO422 Addressable Input Output Module

INTRODUCTION

The FDCIO422 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.
Status indication per LED for each input and output plus 1 LED for general status of the device. Power supply via FDnet (supervised power limited).

• Including 4 EOL devices (470 Ω)
• 3 separators to separate the power limited wiring from the non-power limited. Separators are delivered in 3 different sizes for standard 4 11/16-inch box, 4 11/16-inch extension ring and 5-inch box (RANDL).

The FDCIO422 supports two operation modes: polarity insensitive mode and isolator mode. The module can be wired for either mode (refer to Figure 8). During the isolator mode, the built-in dual isolators will work at both sides of the module to isolate the line short in front or behind the module.

CAUTION
Electric shock!
High voltages may be present on the terminals. Always use a faceplate and the separator(s).

CAUTION
This device is not intended for applications in explosive environments.

Class A/X (UL) is equivalent to DCLA (ULC) Class B is equivalent to DCLB (ULC)

For complete configuration and commissioning of the FDCIO422 also refer to the user documentation of your panel, and for the software tool used for configuration.

NOTICE
To prevent potential damage to the DPU (refer to manual P/N 315-033260) or to the 8720 (refer to manual P/N 315-033260FA) DO NOT connect a FDCIO422 to the DPU or 8720 until the cage is removed from the carrier (Figure 2).

Refer to Figure 3 to locate the opening on the cage cover that allows access to the programming holes which are on the FDCIO422 printed circuit board.
To connect the FDCIO422 to the DPU or 8720 Programmer/Tester, insert the plug from the DPU/8720 cable provided with the Programmer/Tester into the opening on the front of the FDCIO422. Be sure to insert the locating tab on the plug into the slot for the locating tab as shown in Figure 3. Minimum Firmware revision of the DPU must be 9.00.0004, for 8720 must be 5.02.0002.

WIRING

Refer to Figure 11. Refer to the appropriate wiring diagram and wire the addressable input/output module accordingly.

Recommended wire size: 18 AWG minimum and 14 AWG maximum Wire larger than 14 AWG can damage the connector.

(Refer to Figures 2 and 3). Follow the instructions in the DPU manual or 8720 manual to program the FDCIO422 to the desired address. Record the device address on the label located on the front of the module. The FDCIO422 can now be installed and wired to the system.

INPUT NOTES

1. There can be any number of normally open dry contact switches.
2. The end of line device must be located at the last switch.
3. Do not wire a normally closed switch across the end of line device in a normally open wiring.
4. Multiple switches: for open wiring supervision only.

Power limited wiring

In compliance with NEC Article 760, all power limited fire protective signaling conductors must be separated a minimum of ¼ inch from all of the following items located within an outlet box:

• Electric light
• Power
• Class 1 or non-power limited fire protective signaling conductors
  To meet the above requirements, the following guidelines must be observed when installing this input/output module.
  If non-power limited wiring is not used within this outlet box, then these guidelines do not apply. In that case, be sure to follow standard wiring practices.

Separators

The separators must be used when the relay contacts are connected to non-power limited lines. Mount the correct separator in the box used (4 11/16-inch box and 5-inch box). If an extension ring is used in conjunction with a 4 11/16-inch square box an additional separator has to be mounted in the extension ring.
The separators create two compartments to separate the wires as shown in Figure 5.

Wiring entering outlet box

All power limited wiring must enter the outlet box separately from the electric light, power, class 1, or non-power limited fire protection signaling conductors. For the FDCIO422, wiring to the terminal block for line and inputs must enter the outlet box separately from the terminals for outputs.
For the output terminals, protection with a fuse
(depending on the application) is recommended. Refer to Figures 6 and 8.

WIRING AT THE TERMINAL BLOCKS
Minimize the length of wire entering the outlet box.

MOUNTING

Input/output module FDCIO422 can be mounted 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.
For mounting the input/output module in the 5-inch square box use a 4 11/16-inch adapter plate.
Fasten the module to the square box with the
4 screws provided with the box.
Fasten the faceplate on the carrier using the 2 screws provided with the FDCIO422.

Be sure to program the FDCIO422 before fastening the faceplate to the unit.

Configuring the outputs

For configuring the outputs, proceed as follows:

• Determine in which position the contact is active. The contact can be active when it is:

  • Closed (normally open, NO)
  • Open (normally closed, NC)

• After activating the contact remains:

  • Permanently active
  • Active only for a certain period of time. How long the contact remains active can be configured as well (pulse duration). This is only to be used in the application of:
  • Resetting the four wire device F5000 Reflective Beam Smoke Detector, P/N 500-050261.
    The following settings are possible:10 s| 15 s| 20 s
    ---|---|---

• Determine the behavior of the output in case of error on the communication line (open line to the control panel, FDCIO422 power failure). The following configurations are possible for the behavior in case of a failure (default positions):

  • Output position remains the same as before the error
  • Output is activated
  • Output is deactivated

Configuring the inputs

For configuring the inputs, proceed as follows:

• Configure the inputs as 4 Class B (DCLB) or 2 Class A (DCLA).
• Define the type of input (danger input or status input):
  • Status input: triggers status change
  • Danger input: triggers alarm
• Determine the type of monitoring and the monitoring resistors (refer to Figure 10):
  • Class A only open no EOL
  • Class B only open RP 470 Ω
  • Class B open and short RS 100 Ω and RP 470 Ω
  • Define the input filter time. The following settings are possible:
    0.25 s| 0.5 s| 1 s
    ---|---|---

The configuration of the input must correspond to the actual wiring.
An EOL must terminate all unused inputs.

Follow the instructions in the corresponding panel manual for programming the FDCIO422 properly: P/N A6V10333724 and P/N A6V10336897.

• The 2x Class A inputs are identified by the panel as Input 1 and Input 2.
• Class A and Class B cannot be configured at the same time. 2x Class A or 4x Class B.

• Figure 10 FDCIO422 input wiring Class A and Class B
  (For details of Line 1 and 2 wiring see Figure 8, for details of the input wiring see Figure 11.)
  In the device line, up to 30 of any compatible devices in polarity insensitive mode with 20 ohms max line resistance can be isolated between two modules in isolator mode in a Class A Style 6 wiring.
  In the device line, up to 30 of any compatible devices in polarity insensitive mode with 20 ohms max line resistance can be isolated behind one module in isolator mode in a Class B Style 4 wiring.
  HLIM isolator module and SBGA-34 sounder base cannot be used in the same loop with the modules in isolator mode.
