To allow a medical staff who has responded to call to intuitively identify a medical ward from which the call has been output, without operating a corridor light uselessly.

When a recovery operation part 25 of a master unit 20 is operated while a corridor light notification part 13 is in operation, the corridor light notification part 13 is stopped after a prescribed time passes and, when a corridor light recovery operation part 14 of the corridor light 10 to which a cordless handset 1 that has called is connected is operated, the corridor light notification part 13 is immediately stopped, and therefore notification of the corridor light notification part 13 is performed even when the medical staff who has operated the recovery operation part 25 is supposed to come near to the medical ward, and the medical staff intuitively identifies the medical ward from which the call has been output. Whereas, when the corridor light recovery operation part 14 is operated, the corridor light notification part 13 is immediately stopped, however since the corridor light recovery operation part 14 is near the medical ward from which the call has been output, the immediate stop of the corridor light notification part 13 does not disturb the medical staff to identify the medical ward from which the call has been output and the corridor light notification part 13 is not uselessly operated.
