<P>PROBLEM TO BE SOLVED: To easily allow a sound pressure measurement test of a speaker in consideration of a position where an alarm is not installed as well and to appropriately and promptly take a countermeasure when a fire occurs during the sound pressure measurement test. <P>SOLUTION: When a sound pressure measurement test of an alarm 10-1 is performed, a test device 100 is operated at a position distant from the alarm 10-1 by a predetermined sound pressure measurement distance, and an individual ringing test instruction signal is transmitted with weak transmission power. The alarm 10-1 receives the individual ringing test instruction signal from the test device 100, repeatedly outputs a predetermined part in an abnormal alarm tone as a test tone to make a noise level meter 102 measure sound pressure. When the test device 100 transmits a simultaneous ringing test instruction signal with transmission power equivalent to those of house alarms, house alarms 10-1 to 10-5 can simultaneously output test tones. <P>COPYRIGHT: (C)2013,JPO&INPIT |
