LoRaWAN Wireless Smoke Alarm

The LoRaWAN wireless smoke alarm utilizes low-power wireless LoRa chips and an intelligent microprocessor to process alarm signals, enabling ultra-long-distance data transmission. It features dust and insect resistance, immunity to external light interference, and is designed to ensure product stability. This product responds quickly to visible smoke produced by slow smoldering or open flames, promptly alerting users to ensure the safety of life and property. It is widely suitable for indoor and outdoor smoke monitoring in environments such as residences, factories, shopping malls, hotels, restaurants, office buildings, school buildings, banks, libraries, and warehouses.

Instructions for Use

Sensitivity Test

The detector should be tested regularly to ensure proper operation. It is recommended to test once a month. Press and hold the test button for more than 3 seconds to put the detector into test mode. If the alarm indicator flashes rapidly and the buzzer emits a "beep-beep-beep" alarm sound, it indicates that the detector is functioning normally.

Alarm and Mute

When the surrounding smoke concentration reaches the alarm threshold, the detector will sound an alarm and the LED indicator will flash rapidly. Press the test button at this time to put the detector into mute mode. In mute mode, the LED flashes rapidly, and the buzzer stops sounding. The mute duration is 10 minutes. If the smoke concentration continues to rise, pressing the test button will be ineffective. When the smoke concentration falls below the alarm threshold or the mute time expires, the detector will automatically exit mute mode and resume normal smoke detection.

Network Signal Test

Press and hold the test button for more than 3 seconds to put the detector into test mode. At this time, the detector will send a wireless alarm signal to the main station.

Low Battery Voltage

When the detector's buzzer emits a "beep" sound approximately every 42 seconds, and the LED indicator flashes once, it indicates low battery voltage. The detector will send a wireless alarm signal to the main station to remind the user to replace the battery. Otherwise, it may affect the normal operation of the detector.

Fault Check

When the detector's buzzer emits two "beep-beep" sounds approximately every 42 seconds, and the LED indicator flashes twice, it indicates a fault in the infrared photoelectric sensor.
