Triple Phase Complete Stand-Alone Multi-Mode Door Controller

The LeesTech AL-2 Auto Logic Controller is a stand-alone, multi-mode automatic door controller engineered for seamless integration with security and building management systems. Designed for demanding environments such as carparks, hospitals, schools, and industrial facilities, the AL-2 offers flexible logic control with Toggle, Auto Close, and Security Close operating modes.

Housed in a rugged IP65-rated plastic enclosure, it includes contactors, an electronic overload relay, and a padlock-isolating switch, ensuring safe and reliable operation. The AL-2 is available in both single-phase (0.75 kW) and three-phase (2.2 kW) configurations, with the three-phase option built for heavy-duty commercial doors and gates.

• Three-phase design — suitable for 400 V AC 50 Hz motors up to 2.2 kW.

  • Toggle Mode – functions like a standard remote garage operator (open/close on impulse).

  • Auto Close Mode – door closes automatically after a 3–60 second delay.

  • Security Close Mode – closes door 1.5 seconds after vehicle passes the beam to prevent tailgating.

• Future-proof design — can be upgraded or reconfigured as system requirements evolve.

• Inputs for: receivers, key switches, safety beams, loop detectors, keypads, and card readers.

• Integration-ready — communicates with building management and access control systems.
