product overview

The LoRaWAN-BGY1 wireless smoke alarm uses low-power wireless LoRa chips and intelligent microprocessors to process alarm signals, enabling ultra long distance data transmission. It has functions such as dust and insect prevention, and resistance to external light interference, ensuring the stability of the product from a design perspective. This product has a relatively fast response to visible smoke generated by slow smoldering or bright burning, which can remind users in a timely manner and ensure the safety of life and property. This product is widely used for smoke monitoring in indoor and outdoor environments such as residential buildings, factories, shopping malls, hotels, restaurants, office buildings, teaching buildings, banks, libraries, warehouses, etc.

Product Application

instructions

Sensitivity testing

The detector should be tested regularly to ensure normal operation. Suggest once a month. Press and hold the test button for more than3Second, to put the detector into testing mode. If the alarm indicator light flashes rapidly and the buzzer beeps-drip-The alarm sound of 'drip' indicates that the detector is working normally.

Alarm and mute

When the surrounding smoke concentration reaches the alarm threshold, the detector will emit an alarm soundLEDThe indicator light flashes rapidly. Press the test button at this time, and the detector will enter silent mode. When in silent modeLEDThe light flashes rapidly and the buzzer stops sounding. Silent duration10minute. If the smoke concentration continues to rise, pressing the test button will fail. When the smoke concentration falls below the alarm threshold or the mute time is reached, the detector will automatically exit the mute mode and resume normal smoke detection.

Network signal testing

Press and hold the test button for more than3At this time, the detector will send a wireless alarm signal to the main station to enter the testing state.

Battery voltage too low

When the buzzer of the detector beeps every42There is a 'beep' sound in about a second. at the same timeLEDThe indicator light flashes once, indicating that the battery voltage is too low. At this time, the detector will send a wireless alarm signal to the main station. Remind users to replace the battery with a new one. Otherwise, it will affect the normal operation of the detector.

Troubleshooting

When the buzzer of the detector beeps every42About a second "drip-Drip "twice, at the same timeLEDThe indicator light flashes twice, indicating a malfunction in the infrared photoelectric sensor.
