- Smoke Alarms
Smoke alarms provide an early warning of fire, giving you and your family more time to safely evacuate your home.
Often, home fires occur in the darkness of night when residents are fast asleep. One misconception is that a person will awaken from the smell of smoke. This is wrong. Smoke is a silent killer! Smoke contains many deadly gases, such as carbon monoxide, that will actually put a person into an even deeper state of sleep, causing a person never to wake up. A smoke alarm is your first line of defense to get out alive.
Choosing a Smoke Alarm
- Smoke alarms can be purchased at the majority of hardware and variety department stores. Be sure that the alarms you buy carry the label of an independent testing laboratory.
- Smoke alarms in the City of Marinette should have a ten year lithium battery with a tamper resistant battery compartment or be hardwired directly to your home's electrical system with a battery backup. Either type is effective as long as they are installed and maintained properly (follow the manufacturer's directions).
- Some smoke alarms detect smoke using an ionization sensor while others use a photoelectric sensor. Again, both types are effective as long as they are installed and maintained properly, following the manufacturer's directions.
- Specialty alarms with emergency lights also exist for the hearing impaired.
The total number of smoke alarms and where they are installed depends on the home. Follow these guidelines for determining the number of smoke alarms and where to install them.
- Smoke alarms should be installed
- In each bedroom
- In each sleeping area
- On each floor of the building
- Within six feet of each door leading to a bedroom or sleeping area of each unit
- Do not install an alarm in an attic or other unheated spaces where humidity and temperature changes could affect the alarm's operation.
- If your alarm regularly goes off due to normal cooking in the kitchen, do not attempt to remove the battery. Physically move and reinstall the smoke alarm in a location where the alarm will not continually go off while you are cooking.
- Install smoke alarms following the manufacturer's directions. Most battery operated smoke alarms can be easily installed using a drill, screws, and screwdriver. Alarms hard-wired to the homes electrical system should be installed by a professional. Never install an alarm to a circuit that can be turned off from a wall switch.
- Mount alarms high on a wall or on the ceiling. Avoid dead air spaces. Wall-mounted alarms should be installed so that they are 4 to 12 inches from the ceiling. A ceiling-mounted alarm should be attached at least 4 inches from the nearest wall.
- Smoke alarms are not recommended for kitchens, bathrooms, or garages where cooking fumes, steam, or exhaust fumes could result in false alarms.
