MST Automatic Rescue Device (ARD) For Elevator

MST Automatic Rescue Device (ARD) – High-Performance Emergency Management

The MST Automatic Rescue Device (ARD) is a sophisticated emergency backup solution designed to eliminate the risk of passenger entrapment during power failures. Built with high-grade industrial electronics, the MST series is recognized for its “plug-and-play” reliability and its ability to handle demanding motor loads across residential and commercial elevator sectors.

When the primary power supply is interrupted, the MST ARD instantly takes control of the elevator system, providing the necessary torque to move the cabin to the nearest floor and release the doors. It is a critical safety upgrade for any modernization project or new installation.

Key Technical Strengths

• Dynamic Torque Control: The MST logic is engineered to provide smooth, controlled acceleration during emergency maneuvers, preventing the mechanical “jerking” often seen in lower-quality rescue units.

• Intelligent Phase Monitoring: Continuously tracks the building’s power quality, detecting phase loss or voltage drops before they result in a full system stall.

• Universal Inverter Handshake: Designed with open-architecture logic that allows the MST unit to communicate effectively with a wide variety of global inverter brands.

• High-Density Battery Logic: Features an integrated smart-charger that optimizes the lifecycle of the backup batteries, ensuring maximum capacity is available at the moment of failure.

Reliability & Performance

• Heavy-Duty Chassis: Housed in a ventilated, powder-coated steel enclosure that protects sensitive electronics from the heat and dust typical of elevator machine rooms.

• Comprehensive Self-Diagnostics: Includes a built-in test protocol that allows technicians to simulate power failures during routine maintenance without affecting the main controller logic.

• Safety Interlock Integrity: Natively supports safety chain monitoring, ensuring the ARD only operates when all landing doors and safety circuits are proved healthy.
