H389N standalone muti-sensor smoke and heat detector (hereinafter referred to as the "detector") built-in NB - IoT  module, can detect fire smoke or temperature and an alarm, alarm way apart from the local high decibel sound and light hint, can speak by telephone, SMS, apps alarm information notice to tenants, realize remote alarm. The alarm information can also be uploaded to the smart cloud platform, and the inspectors can quickly confirm it on the scene after receiving the alarm. Through real-time fire detection and quick notification to residents, NB-IOT temperature-sensitive smoke alarm detector can detect the fires in time, remind relevant personnel to deal with them, and control fire in the bud.
