<p>PROBLEM TO BE SOLVED: To prevent noise problem occurrence by a battery-powered alarm in which a battery is not properly replaced.SOLUTION: A battery-powered alarm includes notification means which performs a startup notification. The alarm sends electric current to a prescribed circuit and intentionally increases power consumption at startup before the startup notification. After stopping due to battery exhaustion, execution of the startup notification on the restarted alarm by recovery of cell voltage is prevented, and noise problem occurrence by the battery-powered alarm in which the battery is not properly replaced is prevented.</p> |
