Abstract

PROBLEM TO BE SOLVED: To prevent an alarm tone from being sounded many times within a short time by providing a central controller for transmitting a water leak command to a shared part transmission line only concerning the first water leak command when the water leak command is received from one water leak detecting terminal plural times within fixed time. SOLUTION: When the water leak is temporarily recovered and the water leak is generated again, at a water leak detecting terminal 6, a water leak generation command is transmitted to a terminal transmission line 2. This command is received through a terminal part receiving means 7 of a central controller 12 but since a shared part transmitting means 10 is not controlled by an arithmetic control means 11 detecting that the fixed time does not lapse from the 1st water leak generation, the water leak command is not transmitted to the shared part transmission line 9. Therefore, before the lapse of fixed time or more, even when the water leak occurs again, an alarm tone sounding device connected to the shared part transmission line 9 does not sound the alarm tone of water leak. Thus, the alarm tone is prevented from being sounded many times within a short time.

And if the command is for the own station, the own station means 14
Is changed to mode 2.

In addition, by these operations, the alarm sounding device connected to the common unit transmission line 9 sounds the alarm sound of water leakage.

Next, when water leakage occurs again at the water leakage detection terminal 6, the control means 5 does not transmit a water leakage occurrence command because the storage of the storage means 14 is in mode 2.
As a result, the alarm sounding device connected to the common unit transmission line 9 many times within a fixed time does not sound the alarm sound of water leakage.

Next, when water leakage occurs again at the same water leakage detection terminal 6, the control means 5 controls the alarm sounding means 21 because the storage of the storage means 20 is in mode 4. No alarm sound. Further, the water leakage occurrence command is transmitted to the terminal transmission line 2 and the central control device 12 similarly receives the command at the terminal transmission / reception means 17. Since the arithmetic and control unit 11 that has detected this does not control the common unit transmitting unit 10, the water leakage command is not transmitted to the common unit transmission line 9.

Further, by these operations, the alarm sounding device connected to the common unit transmission line 9 sounds the alarm sound of water leakage.

Next, when water leakage occurs again at the same water leakage detection terminal 6, the control means 5 controls the alarm sounding means 21 because the storage in the storage means 26 is in mode 6. No alarm sound. Also, it does not transmit the water leakage occurrence command.

Therefore, the alarm sounding device connected to the common unit transmission line 9 many times within a certain time does not sound the alarm sound of water leakage.
