Working Principle
- The ir sensor constantly detects infrared radiation from fireplace or flame.
- When hearth is detected, the sensor sends a signal to the circuit.
- The buzzer turns on straight away, producing a loud alert sound.
- The alarm stays lively till the fire source is eliminated or energy is disconnected.
This ensures brief fire detection and early warning, lowering the chance of damage.
