ASK433 Photoelectric Smoke Detector

The product is based on the principle that particles in smoke refract infrared light to detect smoke concentrations. The basic detection unit contains infrared emission, infrared reception and optical refraction maze. Under normal circumstances, infrared radiation passes through the optical refraction maze with very little infrared light detected by the receiving portion. The optical refraction maze shields the external light, but does not prevent the smoke from entering the refraction maze. When the infrared emission is entered into the maze, and the smoke enters the maze, the emitted light produces more refraction, and the infrared receiver receives more. Infrared light. When the intensity of the infrared light received at the receiving end reaches a certain threshold, the smoke detector is considered to be effective, thereby generating a smoke alarm signal. The alarm signal triggers the MCU to control the live sound and light alarm and the wireless alarm.

Installation and testing

1. Select the appropriate location to secure the smoke mount with screws. Typically this location is on the central ceiling of the detection area.

2. Pull out the battery insulation paper to energize the smoke, insert the smoked body into the base and fix it to ensure that it is secure.

3. At this point, the smoke LED flashing light should flash at intervals of 40 seconds.

4. Press the test button and the buzzer will beep; press the mute to stop the buzzer.

5. The smoke can be directly blown into the smoke test alarm. When the alarm occurs, the LED light flashes once every 1 second, and the buzzer sounds. You can use the Silence button to cancel the buzzer beep and stop the LED flashing. It can also be used to make the smoke return to the alarm state, and the smoke will automatically exit the alarm state.

Precautions

1. This product is not suitable for use in extremely cold and extremely hot, high wind speeds, and often has a lot of dust and smoke.

2. Every six months, the dust is less environment. It needs to clean the smoke inlet and outlet for one year to prevent the detector from being detected due to dust blockage.

3. When the battery is low voltage, the buzzer will follow the audible prompt to replace the battery when the smoke breathing light is on.
