"Working" Smoke detectors are required by law in New York State to be in every residential home. They should be located on every floor and near sleeping areas. They must be located and mounted in the proper manner, as described by the manufacturer.
DO NOT REMOVE the batteries from smoke detectors (click on the link below)! We see that happening very frequently. People will take them out to use for another device, or will unplug or remove them from the smoke detectors if the detector is giving them false alarms. Normally, when a detector is giving a false alarm, it is due to being too close to an area such as the kitchen or bathroom (steam), or in an area where a draft is present coming from an area such as the kitchen. Rather than disabling the detector, it should be moved to a more suitable location where it is still providing protection, yet not giving false alarms.
Not only are smoke detectors required, but they are just downright smart to have. They work. In the event of a fire in your home, they can give you that extra few minutes needed to safely get yourself and everyone else out of the house before it's too late.
When you go to sleep at night, your sense of smell is one of the first senses to "go to sleep". A working smoke detector(s) can be thought of as your "nose" while you sleep.
If you are a Johnson City resident, please call the Fire Marshal's Office at 729-0428 if you need help in knowing where smoke detectors should be located in your home.
Lastly, if your smoke detectors are more than 10 years old ... replace them.
