One of the occupancy flags is erased by the flag setting means set to (3A) (S-11). After the flag is turned off, it is determined whether or not all the in-room flags corresponding to the number of people in the room have disappeared (S-12). If there is another room flag, it is determined that there is a person remaining in the room, and the ceiling lighting is continuously turned on (S-13). After that, step (S-1) to step (S-6) are repeated again,
Then, if it is determined that there is no occupant determination by the lead of the card reader A (1), the exit determination by the lead of the card reader B (2) continues, and it is determined that all the occupancy flags are not set (S- 12) The ceiling lighting is flickered for a predetermined time, and if there is a person who has entered and remains without ID discrimination, the lighting is turned off at the time of leaving the room, and the room exit promoting means notifies (S-13a). As a result of this notification, if the remaining person immediately leaves the room and reads the card reader B (2), the ceiling lighting is turned off by the lighting turning-off means after a predetermined time ((S
-14), (S-15)). Alternatively, if the card reader B (2) is not read at the time of flicker notification, the ceiling lighting is immediately turned off (S-16).

As described above, by determining the time when all the in-room flags have disappeared as the time when the ceiling lights are turned off, it is possible to efficiently turn on the lights without unnecessarily extending the turn-off time in consideration of the person who remains in the room. Power saving control is possible.

According to one embodiment of the second invention, in addition to the first invention, the intrusion monitoring start means operates the intrusion sensor (6) in the room to activate the intrusion monitoring operation at the time when there is no person left in the room. Enter (S-17 in FIG. 3 (b)). Based on the intrusion sensor signal, the intrusion sensor operates and it is determined whether or not the intrusion is detected (S-18). When the intrusion sensor (6) is activated, an intrusion signal (7) is output to notify the occurrence of intrusion to the building management room or the like (S-19). If the intrusion sensor (6) does not operate (S-18) and the card reader A (1) detects that the ID card has been read (S-20), intrusion monitoring is terminated to prevent malfunction of intrusion detection. (S-21). Then, the process returns to the step (S-2) again and the ID discrimination is performed.
Each of the above means is a function implementing means of the CPU 3a.
