The LAMBDA® 3D entrance-protection system uses 56 infrared emitters and detectors to create an invisible safety net across the elevator entrance. The microprocessor-controlled system continuously scans for interrupted beams. If any beam in the curtain is broken, the LAMBDA system reopens the elevator door instantly without touching passengers.
In addition to its curtain protection, LAMBDA 3D features a second protection system that projects into the hallway to detect passengers as they approach or exit the elevator.
Objects such as dirt, dust or chewing gum can sometimes block the emitters and detectors, causing the system to shut down. LAMBDA 3D incorporates graceful degradation, designed to enhance reliability by preventing unnecessary shutdowns due to blockages. The system also protects doors from damage caused by mail carts, gurneys and other wheeled equipment.
LAMBDA 3D complies with Canada Barrier-free and ADA requirements for non-contact detection.
In addition to new and existing high-rise buildings, the LAMBDA 3D system is ideal for industrial and healthcare facilities where mail carts, stretchers, hospital beds or other heavy equipment is used
