Aim: To design Fire Alarm Circuit using 741- Op Amp Apparatus: TINKERCAD - Online simulation Tool Theory: Circuit Diagram: Fire Alarm Circuit is a simple circuit that detects the fire and activates the Siren Sound or Buzzer along with LED. Fire Alarm Circuits are very important devices to detect fire in the right time and prevent any damage to people or property. Fire Alarm Circuits and Smoke Sensors are a part of the security systems which help in detecting or preventing damage. Installing Fire Alarm Systems and Smoke Sensors in commercial buildings like offices, movie theatres, shopping malls and other public places 1s compulsory. This circuit uses a Temperature Sensor (Thermistor) to sense the temperature. When it senses that the temperature of the environment is increasing above a given threshold, then it gives a signal. APPLICATIONS: Fire Alarm Circuits are very useful in homes, offices, schools, labs, etc. to detect and prevent any disasters due to fire. Fire Alarm Systems can work as a stand — alone devices or be a part of a complex home security system with other security features like smoke detection, intruder alert, motion detection, etc. Ry h ka.
