Hard wired smoke detectors have to have a junction box behind them. These detectors use 120 volts as a working voltage. These types of detectors should be wired with 3 conductor #14 wire. The detector uses the black and white wires for the 120 volt source. Detectors these days have an output signal wire that can be connected to other detectors so that if one trips it will sound the alarm in other detectors that are on the same circuit. This output wire can be connected to other detectors by the third red wire in the 3 conductor cable.

Do you need smoke detectors in each bedroom?
Yes, that's safer. <<>> New electrical code regulations are moving that way. Check with your local electrical inspector to fine out what the regulations are in your specific area.
What was used in fire detectors before americium?
The first smoke detectors are based on optical principles - photoelectric detectors.
What does americium do in smoke detectors?
Yes, americium is used as ionizing source in smoke detectors.
Are smoke detectors composed of carbon?
yeah
Why would hard wired smoke detectors sound if no smoke is evident?
from experience, too much heat,moist or dust affect the performance of smoke detectors and can easily activate the detector.
Is it safe to place smoker detectors on wall instead of ceiling?
Yes. You can mount smoke detectors high on the wall instead of on the ceiling. Make sure that the detector is no more than 12 inches from the ceiling. Since smoke rises, you want the detectors as high as possible.
Where are Masterguard smoke detectors made?
Masterguard Smoke Detectors are made in Coppell, TX.
What are smoke detectors?
Smoke detectors are devices that detect smoke. They are used as warning devices in houses to warn people of fire.
Can smoke detectors detect smoke in the ciling?
No
Are smoke detectors and smoke alarms the same?
no
Are interlinked smoke detectors a good idea?
There are several types of smoke detectors that can be used in the home. Interlinked smoke detectors can interlink smoke and heat detectors for better convenience. Also, wireless units can be configured specifically to your needs. More safety and smoke detector information can be found on: http://www.safelincs.co.uk/Smoke-Alarms/
How long has americium been used in smoke detectors?
Americium become to be largely used in smoke detectors after 1970.
How do smoke detectors detect smoke?
Smoke detectors detect smoke by not detecting it. They sense not the smoke, but the oxygen levels surrounding it. when the oxygen levels drop, or when smoke replaces the oxygen, the alarm goes off.
What year were smoke detectors invented?
Smoke detectors were invented in the year 1967. :P
What is the most efficient smoke alarm?

What gauge wire is used to run smoke detectors?
14-3 Is the standard wire use for residental smoke detectors.
What household item contains radioactive isotope americium 241?
