To provide a living accident monitoring system which can select whether or not automatic switching from absence setting to presence setting is performed according to the existence or non-existence of a pet, the existence or nonexistence of an apparatus which automatically uses water or the like, and thereby erroneous notification does not occur.

The living accident monitoring system comprises an integrated entrance set 1, a living room master set 5, a management room master set 3, a control set 2, and a living accident monitoring sensors such as a water sensor 9 for detecting the use of water and a moving object detection sensor 10 for detecting resident motion to monitor a resident state. The living accident monitoring system also includes: a presence/absence changeover switch 6 which sets whether or not monitoring by the living accident monitoring sensors is performed when returning home when the resident goes out of doors; and an absence automatic changeover switch which sets whether or not control for automatically switching to the presence state is performed when the living accident monitoring sensors can detect the resident due to the use of water, resident motion or the like in the absence state of the presence/absence changeover switch 6.
