| | | Molded Circuit Breaker(MCCB) Protects the elevator manufacturer control equipment from unusual voltage surges in the building power supply. Overspeed Governor Located in the machine room, engages the govemor rope, causing activation of the elevator safety device, should the elevator car accelerate beyond the predetermined maximum speed in the "down" direction. Prevent the elevator from travelling beyond a terminal landing, independently of the functioning of the operating device. | | |
| | | Cause power to be removed from the drive motor, independent of the terminal limit switch function, should the elevator pass either terminal landing. Emergency Exit To be opened only from outside the elevator car, allows removal of passenger in extreme emergency situations. Further movenent of the elevator is prevented until the exit design panel is closed. Emergency Cab Lighting Provides interior cab lighting, should there be a failure in the building's normal power supply. Safety Device Located beneath the elevator car, brings the car to a safe stop, should the elevator overspeed in the down direction. Hoistway Door Unlocking Device Located in a hoistway door panel, provides hoistway access to assist passengers within the cab in the event of an emergency or power failure. Door Deterrent Device Prevents the elevator car door from opening unless the elevator is located within the specified zone at a landing. Interphone System Provides emergency communication between passengers in the elevator car, the elevator machine room or building personnel in a design security or maintenance room. Door Reversal Device Mounted on the leading edge of the car door, causes the car and hoistway design doors to reopen, should an obstruction be encountered when the doors are closing. | | |
