<P>PROBLEM TO BE SOLVED: To provide an alarm capable of shortening the detection delay time and reducing consumption of a battery. <P>SOLUTION: In a gas alarm, while sampling is performed with a period of 30 seconds, a sampling period is changed so as to be shortened by 10 seconds when a microcomputer 10 detects that gas concentration changes from a permission point or lower to a logic start point or higher in one time of sampling cycle (adjacent front and rear sampling points). <P>COPYRIGHT: (C)2013,JPO&INPIT |
