Outstanding features Telescopic layered automatic sliding doors – Falcon Korea The sliding telescopic system is designed so that the rear leaves move at half the speed of the front leaves. With this stealthy coordinated movement, both the rear and front leaves simultaneously reach the full opening point and give you an opening of up to 2/3 of the installed width. Due to four movable wings instead of two, you can enjoy much more convenience in a limited space. All electromechanical transmission equipment is 100% manufactured in the factory in Korea, providing high mechanical durability over time. Operate at maximum energy savings and maximum safety because the 24Vdc power supply to the cotroller, control circuit board, and motor does not cause an electrical short circuit. Brushless DC 24V motor uses permanent magnets that are durable over time. Automatic intelligent microprocessor central controller, sealed cover design limits dust and dirt inside. Record the newly installed initial parameters: load, cruise, wing length, stopping point, etc. Safe against clamping the glass door, self-reversing with very little force.
