FAQ's/Troubleshooting

 

 

Why won't a smoke alarm sound when I push the test button?

Try the following before assuming the alarm is not responding: 

  • Make sure you didn't accidentally press the silence button. (Older models like 4120SB have separate silence and test buttons).
    • You may have accidentally pushed the silence button This temporarily disables the test function on some alarms. You an tell the unit is in silence mode if the red light is flashing, and the alarm "chirps" about once a minute for up to 15 minutes. The test function will return to normal when the smoke alarm is no longer in silence mode. Newer models like the BRK 9120 Series and 7010 Series can be tested while in "Silence" mode.
  • Hold the test button down longer. Try holding the test button down for up to 10 seconds (20 seconds on photoelectric models.)
  • Check the power supply. Make sure the battery is installed properly and snapped all the way in place. Even if the alarm sounded briefly when the battery touched the terminals, you still need to make sure it is snapped securely in place. If the battery is loose, in cannot power the smoke alarm properly. See “The Battery Drawer is open”
  • Make sure the AC power is on. AC and AC/DC units will have a power indicator light (red or green) that shines continuously when they are receiving electrical power.
  • 10-Year Models ONLY
    Model SA340: Be sure the battery pack is installed.
    Models SA10YR or 4010YR: The smoke alarm may not have been properly activated. If the tab broke away before the alarm was activated, you can use a toothpick to move the switch over to activate the alarm.
