NB-IoT Production

NB-Iot Intelligent smoke detector



  1. With a built-in high volume buzzer, it can release a sound alarm above 80 dB.

  2. It can send the informantion to "SANJIANG Cloud" based on the NB-IoT module.

  3. With separate CRU controlling, it can identify the smoke and alarm intelligently.

  4. It is an ideal option for residence, coffee shop, leisure and entertainment places.

  5. It adopts 2 pcs of DC3V lithium battery, and can work for 3 years with low power consumption.

As a residential type photoelectric smoke detector and alarm, JTY-GD-H386N independent photoelectric smoke detector and alarm (“alarm”) can detect the smoke during a fire and send an alarm signal in time. When it gives fire/fault alarm, the alarm signal will also be reported on the mobile terminals with SanJiang Cloud App via NB-IoT module and cloud server. Thanks to its excellent production technology, the alarm is nice, operates stably and needs no debugging. It can be widely used for the fire monitoring and alarming of places including houses, leisure halls, coffee houses, dance halls, etc.
Its built-in high-volume buzzer sounds loudly following an alarm. The unique LEDs in three colors indicate different alarm status. With 2 pcs of DC3V lithium battery , the alarm has quite small power consumption and can operate continually for up to one and a half years. The alarm can realize self check and low power reminding.
