S 2 is output, and the changeover switch 32 is operated by this signal S 2 to switch the power source from the backup power source 28 to the main power source 27 . In other words, the functions of the slave station are stopped. However, since only the memory 24 retains the information of the substation before the power outage, the memory backup switch 33 is turned on by this signal S2 , and the backup power supply 28 continues to supply power (step).
(6) 主電源の復電により電源リセツトが解除さ

（ステツプ）。(7) Collecting the current state data of the grand station via the interface unit 25 and comparing it with the state data of the grand station before the power outage stored in the memory 24;
In order to report the state change data, the state change data is filed in the transfer buffer 23.
(step).
(8) 親局に通報するために自動ダイヤルし接続を
確認する（ステツプ）。(8) Automatically dial and confirm connection to report to the master station (step).
(9) 接続が確認できたら、親局に復電を通報する
と共に停電時と復電時との状態変化データを伝

(10) 通常の監視動作に入る（ステツプ）。(10) Enter normal monitoring operation (step).
このように、子局に小容量の予備電源（停電情
報を１回通報するために必要な容量）を具備する
だけで、子局を大容量の予備電源で無停電化した
場合と同等の機能をもたせることができる。 In this way, by simply equipping the slave station with a small-capacity backup power supply (capacity required to report power outage information once), it is possible to achieve the same functionality as when the slave station is operated without power outages using a large-capacity backup power supply. can be made to hold.

A sub-station installed in each residential unit and connected to an alarm sensor, a sub-station installed in the management room of the housing complex, etc., that collects alarm data from multiple sub-stations, and connected to the multiple sub-stations via telephone line. In a housing group management system comprising a master station installed in a sensor station, the slave station includes a power outage detection means for detecting a power outage of the main power supply, and a power outage detection means for detecting a power outage of the main power supply in the slave station, and a power outage detection means for detecting a power outage of the main power supply based on a detection signal from the power outage detection means. The first step is to switch to backup power.
switching means, means for notifying the master station of a power outage when a power outage of the main power source is detected, a second switching means for switching from the backup power source to the main power source after the power outage is reported, and an operation of the second switching means. At the same time, a memory backup switch is operated to store an uninterrupted memory, a means for notifying the master station of power restoration after the main power is restored, and alarm data of the substation at the time of a power outage in the memory. , means for transmitting state change information obtained by matching the alarm data with the alarm data of the substation at the time of power restoration to the master station.
