Just as its name suggests, an elevator door restrictor is a device that prevents the car door from opening unless the elevator is landed on a floor. Essentially, it prevents the passengers from going out of the elevator at inappropriate floor levels, thereby eliminating fall-related accidents on elevator hoistways.
Although the role of the conventional door restrictor as an integral part of any modern elevator has been a game-changer, what happens when an unexpected power interruption occurs, leaving such equipment all by itself?
Thanks to new and improved elevator door restrictors, ensuring that an elevator door remains shut until it reaches its designated unlocking zone. During unexpected power interruptions, passengers are securely kept inside until their service resumes. Universal, flawless, and 100% code-compliant, these door restrictors are true models of passenger safety and peace-of-mind.
Magnets and Sensors at Work
These elevator door restrictors showcase two vital technologies that set themselves apart from the norm – one that is responsible for holding the lock in place through rock-solid locking mechanisms that use special magnet technologies, and another that signals the corresponding locking systems when the elevators arrive at their unlocking zones.
Use of RFID Technology
It is no doubt how RFID is already an established technology, used by both Boeing and NASA that ensures top-notch accuracy and consistency. For this door restrictor, however, RFID is tasked to ensure that door operations run perfectly – every time.
Despite being usually seen as a mere liminal space that transports users from one space to another, elevator doors can make a lasting impression about your building – depending on how you view them. By upgrading your elevator components starting through their doors, it can dramatically improve elevator service and establish trust among its passengers.
