How long Does a 9V battery last in a fire alarm ?

Date:2015年1月19日 11:00

  Smoke alarms provide vital early warning of a fire, giving people more preparation and escape time. The 9V battery common to many fire alarms needs regular changing and testing to ensure the alarm never fails. Instead of guessing when your alarm battery is going to run out, you should schedule a test and, if necessary, a change on a regular basis. Making sure your alarm battery is always working is a core responsibility of any property owner.
