The Dahua IPMECD-1052-LM4050-T48 is a professional left-hand barrier gate system designed for the secure and controlled management of vehicle entrances and exits, featuring a 4–5 meter telescopic barrier arm. It is suitable for use in parking areas, residential complexes, commercial facilities, factories, public institutions, hotels, and other vehicle access points. Powered by a 24 VDC brushless motor, the system provides low power consumption, quiet operation, high security, stable performance, and efficient operation. The 4–5 meter telescopic barrier arm has an opening and closing time of approximately 4.8 seconds. The rising and lowering speed and position of the barrier can be adjusted, while the integrated digital display provides information about error codes and the operating status of the device. The system supports anti-smash protection through external radar, loop detectors, and infrared sensors. If the barrier arm comes into contact with an obstacle, it automatically rises to help improve vehicle and pedestrian safety. In the event of a power failure, the barrier arm can be raised manually. Equipped with rolling code technology, the remote control system provides secure wireless operation and supports a remote control distance of up to 50 meters. The system also supports fleet mode, allowing multiple vehicles to pass consecutively, as well as a counting function for monitoring the number of barrier opening and closing cycles. The time and speed for delaying the downward movement of the barrier can also be configured according to application requirements. Featuring a metal sheet housing and a corrosion-resistant casing treated with an electrostatic spray finish, the barrier provides a durable mechanical structure. With an IP54 protection rating, the system can operate in temperatures ranging from -35 °C to +65 °C and at relative humidity levels of 10%–90%. The motor has an expected service life of approximately 3 million cycles, while the spring can withstand approximately 800,000 cycles. Supporting an external power supply of 220 VAC ±10% or 110–120 VAC and operating at 24 VDC, the Dahua IPMECD-1052-LM4050-T48 provides a reliable barrier solution for applications requiring a wide vehicle access opening, combining durable construction, safety functions, remote control capabilities, and integration with access control systems.
