PROBLEM TO BE SOLVED: To facilitate wiring work even when a large number of slave doors are provided; and to enable the slave door itself to be locked/unlocked even when one main piece of wiring is broken.SOLUTION: In this centralized control system for the slave door for fittings, the plurality of slave doors 3 and a master station 1 are electrically connected together via a control line of an electric lock; and the slave doors 3 can be individually designated by a control signal from the master station 1. The slave doors 3 are connected in parallel to the one piece of wiring from the control line, and each individually connected in a wired or wireless manner to an external unlocking signal input means 8. The slave door 2 is equipped with a collator 7 which performs collation for determining whether an input signal from each unlocking signal input means 8 agrees with identification information already registered in an its own storage means. The slave doors 3 are individually opened/closed by recognizing the input signal from the unlocking signal input means 8, when the collators 7 provided in the slave doors each receive the input signal from the corresponding unlocking signal input means 8, even in the case where the slave doors 3 are put into the state of being incapable of receiving the control signal from the master station 1 because the control line is broken. |
