. As a result, the locking member 56 receives the signal and releases the lock. This allows those who wish to enter the room to open the door. Also CPO
46 turns off switches 34 and 36 (P47-2
48). When the door is opened within a predetermined time in the above state, the open state detection switch 57 is activated, and the CPU 46 receives the door amount detection signal (P49 to P50). Then, the CPU 46 sends the door opening information code (fit opening data) to RA.
It is read from M47 (P51) and transferred to the signal generator 40 (P53). On the other hand, if the door is not opened within the predetermined time, the CPU 46 reads the door-unopened data as a door-open information code from the RAM 47 (P52) and transfers it to the signal generator 40. As a result, the signal generator 40 generates a signal according to the door opening information code, and the signal is transmitted to the amplifier 4.
