摘要： An inexpensive smoke detector having excellent general versatility and reliability which allows an increase in a range of selecting light emitting devices used for such smoke detectors and which allows reductions in the number of processes and the adjustment equipment, thereby reducing the cost and avoiding human adjustment errors. The smoke detector includes an A/D conversion circuit for measuring an output from a photo transistor which receives a light output of at least a light emitting diode used for a smoke detection. A MPU generates a signal for driving the light emitting diode, based on a value measured by the A/D conversion circuit. The smoke detector also includes an EEPROM. A D/A conversion circuit adjusts a light emission quantity of the light emitting diode based on a value read from the EEPROM. The smoke detector further includes a voltage/current conversion circuit.

摘要： A sensitivity measuring apparatus (10) for use with a fire detector comprises sensitivity measuring portions, a calibrating signal generator (SV), and a calibrator. The sensitivity measuring apparatus also comprises type identifying means (L₁,L₂,L₃) for identifying the type of the fire detector on the basis of the output signal from the fire detector. The apparatus thus needs no manpower in adjustment procedure to regulate the tolerance of the internal circuit. The apparatus also eliminates a source of erroneous measurements in the course of sensitivity measurement of the fire detector.
