Key features

• •Dual-Sensor Smoke Alarm: The smoke and carbon monoxide alarm is equipped with the most advanced photoelectric smoke sensor and electrochemical carbon monoxide sensor, capable of detecting both smoke and carbon monoxide hazards simultaneously, and alerts with an 85-decibel alarm sound.
• •Wireless Interconnected Alarm: This smoke and carbon monoxide alarm utilizes wireless radio frequency technology to transmit and receive information about surrounding hazards. When one alarm detects a danger, all connected alarms will sound simultaneously, notifying everyone of the emergency. (Supports wireless interconnection but does not have Wi-Fi functionality.)
