CONSTITUTION: Each building installation supervisory equipment 10 builds in a clock and makes automatic transmission when it is detected that a set time comes and routine time notice is made to a supervisory center 50 through a telephone line 40. The supervisory center 50 confirms no fault in the line state and the automatic transmission function of each building installation supervisory equipment 10 based on the routine notice and sends current time information to a building installation supervisory equipment 10 from which routine notice comes, Each building installation supervisory equipment 10 compares the current time information with the built-in clock time and corrects a difference if any. Thus, the automatic transmission function of each building installation supervisory equipment 10 is surely checked and the routine notice is allocated in detail programmably to use the line efficiently.
