摘要： PROBLEM TO BE SOLVED: To call attention to, prior to the lifetime of an electrochemical sensor being shortened by freezing in an alarm equipped with the electrochemical sensor which uses water, in order to keep the ionic conductivity of a solid electrolyte membrane. SOLUTION: The concentration of CO is detected in a CO sensor 11 by a microcomputer 10 and an alarm is emitted when the detected concentration of CO becomes preset CO alarm concentration. The thawing weighting coefficient corresponding to thawing rapidity and the freezing weighting coefficient corresponding to freezing rapidity are stored in EEPROM 13 at each temperature section. The ambient temperature of the CO sensor 11 is detected with a thermistor 12. When the ambient temperature is a freezing point or below, the cumulative time is multiplied by the freezing-weighting coefficient at each temperature section; and when the ambient temperature exceeds the freezing point, the cumulative time is multiplied by the thawing-weighting coefficient which is a negative number at each temperature section; and if the sum total (corresponding to the cumulative time difference between the ambient temperature equal to or below the freezing point and that exceeding the freezing point) of the respective multiplied values reaches a predetermined set time threshold, notification of low-temperature freezing is carried out.

摘要： PROBLEM TO BE SOLVED: To detect an abnormality in a low concentration side amplification circuit 3 and a high concentration side amplification circuit 4 for amplifying output voltage from a sensor circuit 2 of an alarm without using an exclusive circuit.SOLUTION: Gas concentration is measured in the low concentration side amplification circuit 3 and the high concentration side amplification circuit 4 by a micro computer 1. A first measured gas concentration is derived in the low concentration side amplification circuit 3 and a second measured gas concentration is derived in the high concentration side amplification circuit 4 by the output voltage of the sensor circuit 2. Whether or not the first measured gas concentration and the second gas concentration are equivalent is decided. When the measured gas densities for both are not equivalent, determination of a failure in the low concentration side amplification circuit 3 or the high concentration side amplification circuit 4 is made and a display of the failure is made on a display section 5. An alarm is given when the second measured gas concentration on the high concentration side is less than a concentration for switching point and the first measured gas concentration on the low concentration side is that for the switching point or more.

摘要： PROBLEM TO BE SOLVED: To prevent an influence of an output of a smoke sensor 12 due to noises, in a fire alarm having the smoke sensor 12. SOLUTION: A control unit 11 uses a sensor drive circuit 13 to cause a light emitting unit of the smoke sensor 12 to emit pulsed light, and receives input of a light reception signal from a light receiving unit. The light reception signal is converted from analog to digital form in the control unit 11 and received as measurement data. The measurement data are sequentially stored in a ring buffer of a RAM 11c. Three pieces of measurement data in the ring buffer are subjected to moving average calculation. The results of the moving average calculation are stored as smoke concentration Si. The smoke concentration Si is compared with a fire determination threshold value (10%/m), and a warning state is set if a value equal to or higher than the fire threshold value is detected five times. If, in the warning state, a value equal to or less than an alarm cancellation threshold value (8%/m) is detected twice, the warning state is canceled. If the absolute value of a difference between the current measurement data and the previous measurement data exceeds 8%/m (tolerance of changes), the current measurement data is deleted and not used in the moving average calculation.

摘要： PROBLEM TO BE SOLVED: To reduce install time of a gas leak alarm while preventing misalarming due to variation of an air base caused when a gas sensor 1 of the gas leak alarm is energized and heated.
SOLUTION: A stationary alarm determination value (Vo) determined for the air base in a stationary state of the gas sensor 1, an increase value (ΔV) being an increment of an alarm determination value, and an initial time Ti up to when the air base of the gas sensor 1 enters the stationary state are stored in a storage unit 4. A power circuit 2 starts energization and heating to the gas sensor 1'. A peak value of a sensor output 1 right after the energization and heating are started is detected. When the peak value has the same polarity with the stationary alarm determination value, a value obtained by adding the increase value (ΔV) to the peak value is set as an alarm determination value. The stationary alarm determination value (Vo) is set again as an alarm determination value an initial time Ti after the start of energization and heating.
