A low battery warning (“LB”)lets you know it is time to change the battery; a smoke warning (“HHH”) lets you know the dangerous smoke is leaking.
  • 2-in-1 Highly Sensitive Alarm: Combination smoke alarm and carbon monoxide alarm has a built-in intelligent chipset. The photoelectric smoke sensor and electrochemical CO sensor with the Intelligent Real-time Monitoring System complies with UL 217 and UL 2034 standards, which ensures the highest level of safety and reliability. The highly Sensitive 2-in-1 co and smoke detector combo is accurate and reliable, suitable for house, bedroom, living room, garage, hotel, indoor, vehicles, factory.
  • Home Protection: When the smoke detector is working, it will cut the risk of dying in a home fire by 50%, and that's important because a home fire starts every 83 seconds! The faster you know about a fire, the faster you can escape from the fire.
  • Good Quality: The smoke detector has passed UL certification, its quality is guaranteed. The smoke alarm don't contain any radioactive material and won't cause harm to human's body.
  • Fault Signal Alarm: The photoelectric smoke alarm is very easily tested only by pressed the button more than 5 seconds, the low battery will have a signal alarm which will recall you to change a new battery.
  • Photoelectric Technology: The smoke alarm uses a photoelectric sensor to ensure that fire smoke can be detected in advance, giving family more time to escape. Besides, the photoelectric sensor is purer than the ion sensor, and avoids the radiation of the ion sensor.
  • 10 Years Life Time: The smoke alarm can be 10 years life time and has 10 years life time non-repalced battery. You won't worry about replacing the battery any more. And it can save energy and protect environment.

  • Test-reset button tests alarm circuitry
  • Self-activation – Alarm automatically activates when attached to the mounting bracket.
  • Photoelectric sensor – Smoke alarm contains advanced photoelectric sensor that may detect visible particles (associated with smoldering fires) sooner than ionization alarms.
  • Sealed-in lithium battery – Sealed-in lithium power supply; No battery replacement required over the 10 year life of the alarm. Eliminates worry about battery removal or unauthorized deactivation of alarm.
  • Voice alarm – Announces the hazard type detected thereby helping to speed up the correct reaction. Alarm announces “Fire” when a smoke or fire hazard is detected and announces “Warning Carbon Monoxide” when a CO hazard is detected.
  • Combination smoke and carbon monoxide alarm – Smoke and CO sensing technologies work together to detect real fires faster and reduce nuisance alarms.
