Pro-Tection Shaft Protection Card

If individuals unauthorized to operate the elevator use an elevator key to open the landing doors, it poses a risk to elevator safety. To mitigate this risk, our "Protection" Shaft Protection Card has been designed. This card ensures elevator safety by activating the protection relay if the elevator doors are manually opened. The "Pro-Tection Well Protection Card" features an INPUT and controls the manually opened landing doors. It cuts the elevator system's stop circuit and assumes control of the system when a door is opened. The warning light indicates the system is under protection. Additionally, the card retains information even when power is interrupted and restored. Elevator repair personnel can disable the protection by pressing two keys on the card.

The "Pro-Tection Shaft Protection Board" can be externally applied to control panels lacking shaft protection features."
