Description
The FAAC Sequenced Access Interface facilitates the integration of the FAAC B680H barrier arm operator with a gate operator, enabling them to function in tandem. This setup is ideal for managing traffic flow, with the faster B680H barrier arm handling high-traffic periods and the slower gate operator ensuring security during low-traffic times.
The interface is housed on a compact PCB, designed to clip onto the standard DIN rail within the B680H unit. Electrical connections are managed through three terminal blocks: one for the B680H, one for the gate operator, and one for the access control device, which requires a simple N.O. (Normally Open) dry contact. The interface board draws its power from the B680H's accessory power supply.
Figure 1: Interface Connections
Figure 1 illustrates the FAAC Sequenced Access Interface's connectivity. It shows the B680H unit, a Gate Operator, and an Access Control Device. The interface board connects to each of these components. The Access Control Device is specified to provide a N.O. dry contact. Terminal connections are labeled for the B680H (e.g., +24, Gnd, Out, Open), the Gate Operator (e.g., Common, Open Limit, Shadow, Full Open), and the interface itself.
Operations
Upon receiving a pulse from the access control device, the FAAC Sequenced Access Interface sends an open signal to the gate operator, initiating its opening sequence. The B680H barrier arm remains lowered until the gate operator reaches its fully open limit switch. At this point, the interface transmits an open pulse to the B680H, causing its arm to raise.
While the gate operator is in the full open position, any subsequent open pulses from the access control device are directed to both the B680H and the gate operator, keeping the entrance open. When no vehicles are detected for a period, the gate operator begins its closing sequence. During this phase, access control pulses are directed solely to the gate operator. The barrier gate arm will only raise again once the gate operator has reached its full open position.
Note: For optimal system performance, the B680H should be configured to close before the gate operator. This is achieved by setting the B680H's pause time to a value shorter than the gate operator's auto-close timer.
Wiring
Refer to Figure 2 for the complete wiring schematic.
Figure 2: Wiring Schematic
Figure 2 provides a detailed wiring schematic. It depicts the terminal connections for the B680H, the Sequenced Access Interface, and the Gate Operator. The B680H terminals include OPEN, CLOSE, FSW, ALARM, STOP, GND, +24, and OUT1 through OUT4. The Sequenced Access Interface has various connection points. The Gate Operator connections include inputs for Open, Shadow, Open Position Limit Switch, and Common, along with power (+24, GND) and output signal terminals.
Note: The Gate Operator is permitted to close only if the B680H status indicates it is closed (FCC engaged), which is monitored via the operator's Shadow input. It is crucial to install safety devices to prevent the B680H from closing if a vehicle is positioned under the arm, ensuring the Gate Operator remains open.
Programming
The B680H unit should be programmed as follows:
- Program Logic: Select Logic "A" with a pause time shorter than the gate operator's closing time. (Basic Configuration: LO → A)
- Output 1 Setting: Configure Output 1 to be FCC engaged. (Advanced Configuration: 01 → 17)
NOTE: The polarity of OUT1 must be set to match the Gate Operator's Shadow input:
- For a Normally Open (NO) Shadow input: Advanced configuration P1 → y
- For a Normally Closed (NC) Shadow input: Advanced configuration P1 → no
Consult the gate operator manufacturer's instructions for specific programming details.
