  5. Smoke Detector in Drop Ceiling

    I finally located the hardwired smoke detector hidden above the drop ceiling on the finished side of my basement. Manufactured in 1990! I plan to replace it with a photo-electric smoke/CO detector. The detector is close to the stairwell. The furnace, water heater, washer, and dryer are on the...
  6. Smoke detector false alarm

    Electrical
    Last night at 3AM, we were woken up by our smoke detectors going off. We have a system where the detectors are hardwired together and each has a battery backup. The result is that when one unit reports smoke, the whole house screams at like 120 dB, which is not a great way to wake up... No...

  11. Smoke detector wiring?

    Electrical
    Hi, I just purchased my new home and went to install a new wireless smoke detector and found that the one installed (probably from 1975) is wired into something. Can I just pull the wires out? Any dangers here? I can't tell what it is wired into so I would then be leaving some open wires (I...
  12. finding the right smoke detector

    Hey, I moved into my home about 3 years ago. The home was originally built in 2001. Recently (like within the last four months) two of my smoke alarms have gone nuts. Both alarms were model USI-1208, both made in 2001 Dec 08. Apart from these two detectors, there are three others in my...
