Vg-2 is a radar detector detector used by police in areas that its illegal to posses a radar detector. However, its barely used as most police departments now use to spectre1-5.
Yes, even though they do emit ionizing radiation. The amount of radiation emitted from a smoke detector is about 1 hundredth of a millirem per year. The background radiation from radioactive isotopes in the ground is about 300 millirem per year. So the ground your standing on right now is exposing you to more radiation then your smoke detector ever will.
It is not a good idea to work on any electrical circuits with the voltage on. Depending on the year when your smoke detector was installed it might have a quick disconnect to change out the device without having to physically having to undo any wire connections. Earlier models had screw terminals that connected to the circuit. Turn the circuit breaker off that supplies the voltage to the smoke detectors. Copy on a piece of paper the wire colours that are on the specific terminals of the detector. Replace the wires on the same terminals on the new detector. Turn on the breaker, the smoke detector will beep and then go quiet, They are now monitoring your home again. Don't forget, when you have the power off, vacuum the other detectors to get rid of built up dust that can cause nuisance tripping.
