• Test smoke detectors monthly by pushing the "test" button or using other procedures recommended by the manufacturer.
• Install new batteries annually or whenever the smoke detector makes a "chirping" sound. The chirping sound indicates that the battery in the smoke detector is nearly dead and needs to be replaced immediately.
• To help you remember to install new smoke detector batteries annually, try changing the batteries every fall when you change your clocks back from daylight savings time.
• Never "borrow" a battery from a smoke detector. You might forget to replace it in a timely manner.
• Gently vacuum the outside of smoke detectors monthly to remove dust and cobwebs and to allow for proper airflow through the vent holes.
• Replace smoke detectors if they are more than ten years old.

Smoke Detectors for the Hearing Impaired

• Certain models of smoke detectors come equipped with a built-in strobe light (as well as an audible alarm) that can alert the hearing impaired in the event of a fire.
• Because the strobes used in such detectors generally require 120 Volts, most smoke detectors for the hearing impaired must run on household current rather than on batteries.
• For a list of manufacturers that distribute smoke detectors for the hearing impaired, please call the National Fire Protection Association's Center for High-Risk Outreach at 617.984.7826.
