INSTALLATION AND OPERATION MANUAL

FDC80 Series

8-CHANNEL SUPERVISED CONTACT CLOSURE

The FDC80 contact closure transmitter and receiver provide transmission of up

to eight independent supervised contact closures over either one optical fiber or

two wire RS-485 link. Microprocessor-based logic sends the contact information

in packets that are ordered and encoded, ensuring extremely robust transmission.

Packets that are garbled, packets out of sequence, and transmission bit errors will not

cause random changes of state on the contact relays. The receiver unit is offered in

both latching and non-latching relay configurations.

Multiple levels of supervision and receiver alarm control can be selected. See Figure

7 on Page 4 for switch settings.

Each module incorporates power and individual status indicating LED’s for monitoring

confirmation of contact closure of each of the eight channels. See Figure 8 on Page 4

for an explanation of the LED indicators.

These units are interchangeable between stand-alone or card mount configurations.

See Figure A on Page 7 for mounting instructions.

See Figures 1 – 11 for complete installation information, following the Application

Note on Page 6.

INSTALLATION AND OPERATION MANUAL FDC80 FIGURE 7 – SWITCH SETTINGS The switch is located on the front panel of each unit. Transmitter 1 - Series Supervision 2 - Parallel Supervision Receiver 1 - Fiber Alarm 2 - Contact Fault Alarm TX: T he transmitter switch selects the supervision method, and this information is automatically transmitted to the receiver module. There are four levels of supervision. NONE: S1-OFF, S2-OFF. No supervision is active.

Place close to the switch for optimal results. FIGURE 11 – RS-485 CONTACTS In RS-485 products (FDC80(T,R)485), the contacts can be transmitted over a pair of wire instead of fiber. Since communication is simplex only, just two wires are needed: A and B.

INSTALLATION AND OPERATION MANUAL FDC80 APPLICATION NOTE LATCHING RELAYS: Latching relays are typically used when the application must insure that the contact outputs will not change state when either power is lost or the fiber is broken. This is a common requirement at high security gate entrance locations, where the gates must not open under any abnormal operating condition. In other words, they must open ONLY when commanded via the contact input state.
