People who are not attendant to the elevator service can endanger the safety of the lift, if they open the landing doors by using the liftkey. In order to prevent this situation, our Shaft Protection Card "Pro-tection" has been developed to protect the elevator and to secure the system when the elevator doors are opened manually.
The "Pro-Tection Shaft Protection Card" have an INPUT and controls landing doors opened by manual way and in case if one of the door is opened it activates protection reley, cuts the stop circuit of elevator system and takes the system under the control. When the warning flash light turns on it indicates that the system is under the protection. It saves the information on the card if the electricity is switched off and on again.
The protection can be disabled by pressing the two buttons located on the card, which is well-known among elevator repairman.
To all control panels without shaft protection feature "Pro-Tection Shaft Protection Card" can be applied by externally.
