RCBII can set a password on each floor. Password ***3 digits, choose from 6 password buttons. The six buttons are CSA 1-CSA6. For convenience, you can choose six command buttons as password buttons. For example, if the command button on the sixth floor is 1, the address of CSA 1 is set to 08- 1, and CSA2 is 09- 1. . . . . . CSA6 is 13- 1.
