• Smoke alarms should be installed in or near every bedroom and on every level of the home. Some can be interconnected so that when one sounds, they all sound.
• An ionization alarm typically is more responsive to flames and a photoelectric alarm is more responsive to smoldering fires. Ideally, both types or a combination alarm (photoelectric and ionization) should be installed.
• Alarms should be tested monthly by pushing the test button.
• Smoke rises, so alarms should be installed high on a wall or on a ceiling.
• If an alarm "chirps," it means the battery is low and should be replaced immediately.
• Replace all alarms when they are 10 years old, or sooner if they fail tests.
• Alarms should have labels of recognized testing laboratories.
• Alarms that are hardwired (and include battery backup) should be installed by a qualified electrician.
• If cooking fumes or steam set off kitchen alarms, replace them with ones that have a "hush" button, which reduces the alarm's sensitivity for a short period.
• Alarms that use strobe lights are available for those with hearing problems; vibration devices can be added to these alarms.
