What was used in fire detectors before americium?
The first smoke detectors are based on optical principles - photoelectric detectors.
Do wired smoke detectors mount on electrical boxes?
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.
What brand of motion detectors have the the greatest range?
There are many levels of long range motion detectors, personal use and commercial use. Some motion detectors can detect movement up to 8-10 miles away. Some good brands for long range motion detectors are Honeywell and KNX.
What are facts about earthquake detectors?
They are flowers
Are smoke detectors composed of carbon?
yeah

What was used in fire detectors before americium?
The first smoke detectors are based on optical principles - photoelectric detectors.
Can radar detectors tell you if a cop car is near you?
Only if he has his radar gun on. Radar detectors are not cop detectors.
What is full form of QB detectors?
Quartzoid Bulb Detectors
What is the difference between laser detectors and radar detectors?
Laser detectors detect laser speed devices and Radar detectors detect radar speed devices.Unfortunately it's usually too late when they detect Lasers.
Which stores sell the best white metal detectors?
There are many great stores that sell quality white metal detectors. These include Regton, OKM Metal Detectors, Kelly Co Detectors, as well as retailers on the Amazon website.
When was Bureau of Alien Detectors created?
Bureau of Alien Detectors was created in 1996.
When was Kellyco Metal Detectors created?
Kellyco Metal Detectors was created in 1955.
What is photoionization?
The removal of one or more electrons from an atom or molecule by absorption of a photon of visible or ultraviolet light. (Also known as atomic photoelectric effect.)
