1) has a self-test and fault alarm functions, user-friendly maintenance and use. 2) can be connected to any control device outputs a control signal or a button or remote control, to achieve a single two-way traffic control. 3) automatic reset function: Every swing of 90 degrees, and detect people and objects passed, automatically reset, or (multi-speed adjustable time delay within a specified time) does not pass, the system will automatically cancel the access privileges of and return to the initial position. 4) Light indicator: High brightness traffic light status indicator to guide traffic. ? Anti-trailing features: 5), after the current face of people and objects through the process of resetting the arm, if a person or punch trailing brake, arm automatic locking and alarm. 6) (when equipped with infrared detection of the case) is the current face of people and objects are not completely through, if people followed the break-in, then start infrared alarm. 7) Fire input: connect with the fire alarm signal, uninterruptible power off the pole normally open. 8) alarm function: the illegal traffic or when the red gates, automatic alarm prompts. 9) adjustable speed: the speed of the arm opening and closing speed adjustable 8, the user can be set according to actual needs. 10) anti-reverse function: the arm reset process, such as the occurrence of external reverse swing arm, and the arm automatically locking alarm, be reversed external force disappears automatically restore access. 11) automatic protection function: When the external force to prevent normal arm movement, and force continuously, the system will automatically detect and automatically protect into hibernation after five times. The next time when the legitimate signal input, the gates will automatically return to normal. 12) Bumper function: the illegal traffic or the red gate, the brake lever locking angle corresponding buffer, the realization of human anti-injury. Also greatly reduces the mechanical damage due to collision produced. 13) unattended: automatic power-off arm normally open, power is automatically reset (blocking traffic). 14) Quick Mute: electric power, mechanical zero wear.
