Emergency Door Release

EDR-1, or Emergency Door Release 1, is a safety feature commonly found in elevator systems. The EDR-1 allows occupants to manually open the doors of the elevator car in the event of an emergency, such as a power failure or a malfunction.

The EDR-1 is typically located inside the elevator car and consists of a button or lever that can be pulled or pushed to release the doors. When the EDR-1 is activated, it interrupts the normal operation of the elevator and allows the doors to be opened manually. This allows occupants to exit the elevator safely in the event of an emergency.

It is important to note that the EDR-1 should only be used in emergency situations, and not to exit the elevator during normal operation. Attempting to use the EDR-1 during normal operation can be dangerous and can cause damage to the elevator system.

In addition to the EDR-1, elevators are typically equipped with other safety features, such as emergency lighting, communication systems, and various sensors and controls to prevent accidents and ensure passenger safety.
