Aligning recessed lights with smoke detectors
Comments (0)My hallway ceilings throughout the house has a line of recessed lights. My electrician needs to wire smoke detectors to those areas in the ceiling. Should I have him place the smoke detectors so they line up with the recessed lights down the center? I'm thinking that would look better than having them randomly placed and too noticeable if they were off center....See MoreNew Outlet off Smoke Detector
Comments (13)"For safety reasons, smoke detectors should be on their own circuit. You don't want someone to trip the breaker with a hair dryer or something and cut the power to your home's smoke detectors." That is why AC powered smokes have a battery backup, and should start chirping if the AC is missing. "For safety reasons, smoke detectors should be on their own circuit. You don't want someone to trip the breaker with a hair dryer or something and cut the power to your home's smoke detectors." This is actually a better solution, and with the AFCI requirement the smokes need to be on the bedroom breaker anyway since they are an 'outlet.' The same thing goes for that freezer in the basement. It should share a light used on a daily basis. You NEED to know if power is off....See MoreSmoke Detector hard wired, no battery!
Comments (8)lol. Interestingly enough if he were going to remove just one wire, I would have removed the black one... Either way, it's not a bomb. It is, however, a hazard to have ANY live wires "sticking out" or otherwise not properly "ended". If you choose to get rid of the hardwired smoke detector altogether, "cap" the wires with "wire nuts" and put a blank round plate over the hole (you can buy the plate at almost any hardware store. Don't try to make one yourself. Same with wirenuts.) Installing a new hardwired one is similarly simple. Match black to black, white to white, attach with wires, and secure it to the wall/ceiling per the instructions (usually two screws). I haven't seen a smoke detector with a ground wire since the early 80s, but if you somehow manage to find one, it'll have a green wire that needs to be connected to the bare copper wire in the wall/ceiling, also with a wirenut. No matter which option you choose, you'll want to turn off the power before mucking around with them wires. Since you probably have no reliable way to TEST them, I'd recommend turning off the power to the entire house....See MoreTreadmill setting off newly installed smoke detectors
Comments (17)A surge protector may not/is likely not going to work, many simply try to clamp/limit any voltage spikes that might appear on the power line. That doesn't stop noise from passing in both directions. Your treadmill is likely using an internal variable frequency or duty cycle power supply to control the motor speed and it is the switching noise from this process that is likely getting back onto the power line and triggering the smoke detectors. Simple surge protectors won't be able to stop this kind of electrical noise from passing through. I think you need a true EMI filter such as this between your treadmill and the incoming power: https://www.galco.com/buy/Qualtek-Electronics/854-03/003?source=googleshopping&utm_source=adwords&utm_campaign=&gclid=Cj0KCQiAlZH_BRCgARIsAAZHSBkx1NY1NwCUy1KJ2qF5oUzpNn-jS_qaiPTiwDtGuTlA8t0t8JYkHZEaAtR4EALw_wcB There are many sources for such a filter. It just needs to be sized to the max current draw of what is being protected, and then encased so the connections aren't exposed....See MorePatrick
