A fire alarm using the IC 555 operates in a monostable mode, where it detects changes in temperature or smoke. When a sensor (like a thermistor or smoke detector) triggers the circuit, it sends a signal to the 555 timer, causing it to output a high signal. This output can activate a buzzer or alarm, alerting users to potential fire. Additionally, the timing components can be adjusted to set the delay before the alarm sounds, allowing for false alarm mitigation.
