Early fire detection is vital to the safety of the people in your business or establishment. Proper installation and routine service inspections of alarm systems can help save lives and property. A malfunctioning alarm can be just as dangerous as a fire itself. It is a good idea to change the battery of your fire alarm at least once a year. Once a month you should push the “test button” to make sure the alarm is still functioning. Also clean your smoke alarm using a vacuum cleaner, but don't remove the alarm's cover. You should also replace smoke alarms every 10 years.
