Peerless Circuit Diagram For Smoke Detector Single Phase Motor Winding Connection

The diagram shows the two basic types of smoke detectors 2 wire and 4 wire. Two wire smoke detector circuit. After installation put the battery and switch on the main. The working of the circuit is simple and is explained below. Power to operate the smoke detector is supplied on the same 2 wires as the detection circuit. Here s how they work. The main supply is 120v ac in us and 230v ac in eu. A bc547 npn transistor is used to to drive buzzer whenever it detects smoke. A 10k pot is also used for calibration. Here the lm358 s inverted terminal is interfaced with pot to so as to adjust the sensitivity of the circuit.

With the onset of summer season possibilities of fire accidents go up. Smoke detector circuit. Simple smoke detector circuit the photo interrupter module h21a1 consists of a gallium arsenide infrared led coupled to a silicon phototransistor in a plastic housing. A 10k pot is also used for calibration. Two wire smoke detector circuit. The detectors can be directly connected to the db distribution board or an existing wiring like outlet. A 2 conductor cable goes from the main panel connects to each smoke in sequence and terminates with an eolr at the last detector. Smoke detector circuits electrical question.
