About this item

• Two Sensors: Carbon monoxide detector smoke alarm has a 2-in-1 dual sensors, photoelectrical and electrochemical sensors. They work separately, no matter which one reaches their dangerous concentraion, combination smoke carbon monoxide alarm detector will go off with red led flashing
• Readable Digital Display:The screen of smoke detector carbon monoxide detector combo will display the CO or smoke concentration and illuminate when it goes off. This smoke detector has a standby mode, its screen will not be on and no need to worry about being disturbed under a standby mode. Under a standby mode, green led blinks about every 60s
• Loud Beep: This combination smoke carbon monoxide alarm detector has a louder than 85 decibels beep with red LED flashing. It is loud enough to let you know the danger and take ation to avoid it quickly. It is recommended to install more than one in your house for a maximum protection
• Red or Green Led function: This smoke alarm and carbon monoxide detector has a low battery warning, it will go off and blink red led. When dangerous concentration happens,it also goes off and blinks red led. Green led with beep is for test button to detect this fire detector and carbon monoxide detector's different working status
• Green Led Too Bright? : If you feel that the green led is too bright, it is recommended to cover with a transparent pvc until you feel good. This smoke detector is easy to install. Both wall and ceiling are suitable for installation

AI Product Analysis

Core Selling Points

• Dual smoke/CO sensors for independent, precise detection
  • Target Scenario & Pain Points: Users worry about both fire and carbon monoxide risks at home, seeking an integrated solution to avoid the hassle of purchasing and installing separate devices.
  • Value & Benefits: Provides comprehensive, convenient home safety protection. One device addresses multiple threats, reducing purchase and management complexity.
  • Communication Strategy: Title emphasizes 'Smoke and Carbon Monoxide Detector Combo'; first bullet point highlights '2-in-1 dual sensors' and their independent operation.
• Intuitive digital display for real-time concentration alerts
  • Target Scenario & Pain Points: Traditional alarms only use sound and flashing lights, making it difficult for users to determine the type of danger and specific concentration, impacting decision-making.
  • Value & Benefits: Provides clear, quantifiable hazard information, helping users quickly assess threat levels and react appropriately, improving response efficiency.
  • Communication Strategy: Title includes 'Digital Display'; second bullet point details that the screen displays CO/smoke concentrations and illuminates.
• 85dB high-decibel alarm, low-interference standby mode
  • Target Scenario & Pain Points: Users worry alarms may not be loud enough for timely warning, or that indicator lights are too bright during daily use, affecting sleep or daily life.
  • Value & Benefits: Ensures timely hazard warnings while minimizing disturbance to daily life during non-alarm states, balancing safety and comfort.

Product Pros

• Dual-Sensor Precision Detection: Integrates both photoelectric and electrochemical sensors to enable independent detection of smoke and carbon monoxide, providing comprehensive protection that surpasses single-sensor detectors.
• Intuitive Digital Display: Displays real-time CO/smoke concentrations and illuminates during alarms, offering clearer, quantifiable hazard information compared to traditional audible/visual alarms.
• High-Value Two-Pack: Offers two detectors at a competitive price, effectively covering multiple areas of a home and reducing the user's overall safety protection cost.
• Battery-Powered for Easy Installation: Battery-powered design eliminates the need for wiring, ensuring simple and flexible installation. Includes batteries for out-of-the-box use, enhancing user convenience.
• Low-Interference Standby Mode: Screen turns off in standby mode with a low-frequency flashing green LED, effectively minimizing nighttime light disturbance and optimizing the user's sleep environment.

Product Cons

• Questionable Carbon Monoxide Detection Reliability: Customer review summaries clearly indicate multiple users reporting missed CO detections, a critical flaw for a key safety device.
• LED Indicator Design Flaw: Product selling points suggest users cover the overly bright green LED themselves, exposing insufficient design consideration and impacting nighttime comfort.
• Battery Life Conflict with Description: Product specifications list Zinc-Carbon AA batteries, but some reviews mention 10-year lithium batteries, indicating significant information inconsistency and user expectation misalignment.
• Lacks Interconnected Alarm Functionality: Does not support multi-device linked alarms. In complex or large residences, this prevents whole-house synchronized warnings, creating safety blind spots (inferred based on similar product experience).
• Lacks A+ Content Support: Long description is empty; product detail page lacks in-depth graphic/text introductions, hindering the detailed showcasing of technical advantages and building brand trust.
