When something is hard wired, it is wired directly to the house wire. No cord. You just install the smoke detector like you would a light fixture or an outlet.
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.
I don't believe that if you place a smoke detector inside a closed space like above a false ceiling , it will have the same effect than if it was attached to the ceiling on the occupied space side. See the related link for some general guidelines and always check local codes or with the fire marshall for specifics.

A smoke alarm or temperature sensor will also detect quick increases in ambient temperature. If your smoke detector is going off for no reason, it may be too close to a heat source like a stove, bathroom or furnace room, or it may be defective and need servicing.
There are different types of gas leak detection devices. Some can be installed on the wall like a smoke detector. A good place to start looking online could be www.Amazon.com

You can find motion detector cameras on sites like Best Buy's and Fry's. You can also try finding them on sites like Amazon and also on sites like EBay or Craigslist.
