The FAAC 620 electro-hydraulic automatic barrier is engineered around modular mechanical and electronic architectures. Driven by the integrated FAAC 624 BLD microprocessor control unit, the system interfaces with standard access control peripherals, vehicle sensing loops, safety monitored edges, and master/slave multi-barrier networks across industrial and commercial infrastructure.
Compatible Barrier Arm Profiles & Hardware Options
The housing pocket of the FAAC 620 accommodates five distinct arm designs without requiring external hydraulic modifications:
- Rectangular Standard Beam: Rigid extruded profile rated for clear spans up to 5.00 metres.
- Rectangular Beam with Skirt: Compatible with bottom skirt accessories up to designated load limits, counteracted by the compression balancing spring to prevent pedestrian under-crawl.
- Articulated Rectangular Beam: Articulation kit compatible for low-ceiling underground garages and covered parking bays, supporting clearance spans up to 4.00 metres.
- Round Beam: Aerodynamic cylindrical beam profile engineered for high-wind installations.
- Round Pivoting Beam: Compatible with specialized breakaway/pivoting mechanisms for impact protection.
Control Board Terminal Inputs and Safety Detection
The built-in 624 BLD controller features discrete terminal strip connections designed for standard access control automation and safety loops:
- Vehicle Induction Loops: Dedicated terminal inputs for Loop 1 and Loop 2 (the unit is supplied without an inbuilt loop detector, interfacing with external loop amplifiers or dedicated plug-in detectors).
- Command & Safety Terminals: Independent dry-contact inputs for Open, Close, Closing Safety Devices (photocells/safety edges), Stop, Emergency, and 230 Vac (+6% -10%) 50/60 Hz mains power with Earth.
- Dedicated Modular Connectors: Direct interface pins for opening and closing limit switches, motor run capacitor, plug-in inductive loop detector module, and a rod detachment sensor.
Peripheral Outputs & Radio Receiver Interfaces
The 624 BLD motherboard provides 24 Vdc regulated power for auxiliary sensors (500 mA maximum current draw) alongside dedicated switching outputs:
| Output / Interface | Rated Specification | Functional Application |
|---|---|---|
| Accessory Power | 24 Vdc (500 mA max) | Photocells, radar sensors, access keypads, and card readers |
| Flashing Warning Light | FAACLIGHT compatible terminal | Pre-flashing and motion alert indication during barrier transit |
| Status & Indicator Light | 24 Vdc output | Remote barrier status monitoring and gate-open visual indicators |
| Fail-Safe Output | Monitored relay terminal | Safety device self-test verification prior to cycle execution |
| Forced Cooling Fan | Dedicated fan output | Enclosure thermal regulation during high-cycle operations |
| 5-Pin Rapid Coupling | Proprietary 5-pin port | Direct plug-in integration for Minidec, Decoder, or RP/RP2 receivers (such as RP 433 DS) |
| BUS Communication | 2-wire BUS interface | Direct communication with compatible FAAC BUS monitoring accessories |
Synchronized Opposed Arrays and Traffic Management
The FAAC 620 supports inter-cabinet synchronization for wide road dual installations. By integrating an optional auxiliary card, two opposing LH (Left-Hand) and RH (Right-Hand) barrier units operate in master/slave coordination to secure bi-directional spans. The system control unit natively executes 11 programmable operating logics—including Parking, Parkingautomatic, Automatic, Automatic 1, Semiautomatic, Condo, Condoautomatic, FAAC-CITY, Dead-man, Remote, and Custom—allowing native integration with automated revenue collection terminals, external traffic control lights, and PLC-driven industrial checkpoints.
Field Cabling Specifications
For compliant field wiring, power cabling requires one 2x1.5 mm² + Earth cable and one 2x1.5 mm² cable for 230V mains distribution. Field signal and low-voltage command circuits require three 3x0.5 mm² cables and one 2x0.5 mm² cable routed to the low-voltage terminal strip.
