Method 1. When the elevator is bought, it will give you an extra phone,(5 parties talking) directly to the phone in the machine room to realize the communication with the car.
Method 2. The tube of fire department cannot elevator telephone, put in charge of bureau of quality and technical supervision.
If you have to answer the phone in the car, you can buy a bundle of cord (telephone cord cord) to the elevator cable and go over.
Note: it is best not to change the elevator telephone. Use the original telephone provided by the elevator factory. And go to your central control room on the OK pull.
Elevator is 5 side talk. Look for elevator manufacturer to want the telephone is better.
