Description
The DoorKing 6550-384 is the secondary (slave) operator designed for dual swing gate systems using the DoorKing 6550 Series. Built for demanding commercial and industrial applications, it pairs with a 6550 primary operator to provide smooth, synchronized operation for large dual gates weighing up to 2,000 pounds and measuring up to 25 feet in length. Powered by a 1 HP continuous-duty AC motor, the 6550-384 delivers dependable performance in high-cycle access control environments.
Engineered with the same rugged construction as the primary operator, the 6550-384 features a heavy-duty gear reduction system, adjustable electronic magnetic limits, mechanical slow start and slow stop operation, and a breakaway hub that helps protect the gearbox if the gate is struck. The operator communicates with the primary unit to ensure precise, synchronized movement for bi-parting gate systems while maintaining reliable long-term performance.
The 6550-384 integrates seamlessly with DoorKing access control systems, monitored safety devices, loop detectors, and telephone entry systems. When installed with the required monitored entrapment protection devices, the system complies with UL 325 and UL 991 safety requirements for Class I, II, III, and IV vehicular gate applications.
