AC Powered
The 7139 for wall mount is a photoelectric single station smoke alarm designed to give reliable early warning of the presence of smoke where both audible and visual alarms are required. This model is AC powered so an electrician is not required for installation.

The smoke alarm operates on the light scattering principle, a superior method of detection in smoldering fires. It has a pulsing LED light source and a photodiode sensor in a fully screened sensing chamber. When smoke enters the chamber, the infrared beam is deflected onto the sensor. The LED rate increases to 8 times the normal pulse rate, and after the photodiode confirms the presence of smoke for 2 consecutive pulses, it will produce the signal necessary to trip the audible and strobe light alarms.

The 7139 series provides the temporal 3 (T3) evacuation tone as a standard feature. When testing, it may take up to 16 seconds longer to go in or out of alarm.

Features:
  • 177 candela rating (very bright strobe light)
  • Solid state 90dB horn (very loud)
  • Full function test switch (easy for you to test that it is working)
  • Flashes 60 times per minute
  • Meets state, federal, and ADA requirements
  • Temporal 3 (T3) Evacuation sounding device
  • 9ft line cord
  • 9V battery backup included (audible alarm only)
  • UL Listed (USA)

  1. Great product Review by Tom
    Overall Satisfaction

    My daughter has a cochlear implant which needs to be in a dryer overnight and leaves her with just the strobe for the alert. But the simplicity of the product gives us all piece of mind when she sleeps in her apartment at college. (Posted on 12/26/2016)

  2. Terrific Product Review by Marie
    Overall Satisfaction

    I bought this product once over ten years ago. After someone accidentally dropped and broke it, I decided to buy a new one. I heard that it is recommended to replace smoke alarms every ten years anyways. I have been happy with this easy to use product. (Posted on 11/8/2016)

  3. Very Helpful for Deaf family Review by Sandra S.
    Overall Satisfaction

    Now we can be at ease with the new alarm that is suitable for deaf. I had fire department chief to help us out with installing the alarm and where to put it that is best for us. We will order more in few months for other side of our house. (Posted on 11/1/2016)

  4. Excellent product Review by Kay
    Overall Satisfaction

    I am a 98 year old, deaf woman, who lives alone. My son easily installed the smoke detectors, and for the first time in years I have a smoke detector system that works for me. (Posted on 10/11/2016)

    Has set our minds at ease knowing this alarm is in our sons room. He is deaf and has never been as comfortable as he is now. (Posted on 8/4/2016)

  6. So far so good Review by New Customer
    Overall Satisfaction

    Haven't had to use it yet....which is good!!! But the light brightness and the alarm loudness are pretty impressive. Prayers it wakes up our hearing impaired loved one IF the time ever arises. (Posted on 5/21/2016)
