摘要： A photoelectric sensor of the present invention includes a light emitting device and a light receiving device for detecting scattered light due to smoke, a light emitting confirming device which lights up when a quantity of light received by the light receiving device is greater than or equal to a threshold and a test light emitting device for emitting light to the light receiving device during the test, wherein a blinking of the light emitting confirming device is started at a time of a test start, and a quantity of light received by the light receiving device is increased in steps so that the blinking is stopped when the quantity is greater than or equal to the threshold. Accordingly, the sensitivity test can be performed by visually counting the number of blinkings of the light emitting device.

摘要： A fire disaster monitoring system of the present invention has a control unit and a fire sensor. The fire sensor includes a sensor base and a sensor body. The sensor base incorporates a first memory which stores first address information of the first memory. The sensor body incorporates a second memory and a CPU therein. The second memory stores second address information of the sensor body. The CPU includes an address reader, a comparator and an address generator. When the power is turned on, the address reader reads the address information in the first memory, and reads the address information in the second memory. The comparator compares the read pieces of address information with each other. When the comparison result by the comparator indicates agreement, the address generator leaves the address information in the second memory as valid data. On the other hand, when the comparison result indicates disagreement, the address generator writes the address information in the first memory into the second memory.

摘要： A pair of temperature detection devices having different heat time constants and an active device having a predetermined bias are connected in series. The bias is set so as to cause the active device to operate in a saturated region if the temperature is higher than a dangerous level, and to operate in a triode region if the temperature is lower than the dangerous level. The temperature detection devices are chosen so as to cause the voltage generated at the junction of the temperature detection devices to be higher than a predetermined reference voltage if the temperature has been raised to the dangerous level when the temperature is raised slowly, or if the temperature is raised rapidly, even if the temperature is lower than the dangerous level. A constant temperature function and a differential function are generated to detect that a fire has taken place. In another embodiment, one of the temperature detection devices (in series with an active device) is arranged in parallel with the other temperature detection device (in series with a resistor). The relative voltages of the two temperature detection devices are monitored to detect a "too high" or "too rapidly increasing" temperature. The resultant compensation type heat sensor has a reduced number of elements, the cost of which can be reduced and which possess both the constant temperature function and the differential function.

摘要： A thermal analog fire detector which is excellent in measurement precision and resolution in both the high and low temperature ranges and which has a wide range of measuring temperatures. A constant voltage E from a constant voltage circuit is supplied to a CPU, an A/D converter and a constant current circuit. The constant current circuit is connected in series to a thermistor. The constant current circuit is constructed to supply a constant current, the value of which being variable in a plurality of stages, to the thermistor controlled by the CPU. The CPU switches the constant current of the constant current circuit according to the measured temperature data. A voltage V across the thermistor is converted into digital data by the A/D converter, and then the converted data is supplied to the CPU.
