Types of Alarms

Fire

• A fire alarm, the most common type of alarm, can alert the sleeping inhabitants of a home that a fire is occurring. Many jurisdictions require fire alarms to be fully powered at all times. Fire alarm systems can send a signal to a fire department for additional help. Though they can be prone to false alarms from smoke emanating from a home's kitchen or barbecue, fire alarm systems can also send a signal to a fire department for help.

Burglar

• A burglar alarm can detect a home intruder and send a signal to a local police department. If a burglar attempts to open a locked door or window, the alarm system will begin to emit a loud noise and alert the police. Security companies can install burglar alarm systems into homes and charge a monthly fee for their service.

Carbon Monoxide

• Carbon monoxide is a dangerous gas that can seep into homes. Carbon monoxide alarms detect the levels of this odorless, colorless gas in a home to help inhabitants prevent high levels from accumulating. You can buy a carbon monoxide alarm at a home goods store or big-box retailer.

Flood

• A flood can cover and submerge a home in water. Storms and monsoons can cause floods in coastal areas. A complex flood alarm system can cut off water from a home, while a simple alarm system will emit a loud noise to signal that the home is flooding. Owning a flood alarm system can prevent a home from becoming completely engulfed in water or save inhabitants from drowning.
