る。 In the photoelectric smoke detector configured in this manner, the changeover switch 10 is normally connected to the contact A side. A voltage is applied from a power supply 11 to the amplifying circuit 2, switching circuit 3, oscillation circuit 4, and capacitor 7 to carry out a monitoring operation.

であることを知らせる。 When smoke is generated due to a fire or the like and enters the smoke monitoring space of the sensor, the pulsed light from the light emitting element 5 is scattered by smoke particles, and this scattered light is received by the photoelectric conversion element 1. When the smoke detection signal of the amplifier circuit 2 exceeds a predetermined level, the switching circuit 3 operates and issues an output signal. The transistor 8 then becomes conductive and drives an alarm device 9 such as a buzzer. The sound of this buzzer notifies neighbors of the alarm condition.

器９にいたる感知器のほとんどの回路機能が正常
であるかどうかチエツクすることができる。 In the normal monitoring state, when checking the operation of the sensor, the changeover switch 10 is switched from contact A to contact B in the same way as when stopping the alarm. Since the capacitor 7 is normally charged with an electric charge, even if the power supply 11 is turned off, each circuit continues to operate for a short time due to the energy stored in the capacitor 7. A pulse current flows through contact B, and light is emitted. The light from the check light source 6 directly
Or, the photoelectric conversion element 1 may be reflected inside the case.
It is configured to receive light. If each circuit operates normally, the switching circuit 3 operates at the same time as smoke is detected. The transistor 8 then becomes conductive and drives an alarm device 9 such as a buzzer. Since this operation time is performed by the discharge energy of the capacitor 7, it is short. That is, if the buzzer sounds momentarily immediately after switching, it indicates that the sensor is normal. Through this operation, it is possible to check whether the oscillation circuit 4 and most of the circuit functions of the sensor from the photoelectric conversion element 1 to the alarm 9 are normal.

用上非常に有益である。 As explained above, in this invention, the alarm can be stopped when the sensor is activated and the operation check can be performed using the same changeover switch 10, and also in the operation check, by providing the check light source 6. This is very useful in practice, since it is possible to check the functions of almost all the circuits of the sensor with simple operations.
