How to check all interconnected smoke alarms operate correctly? (Mixed wired and Wireless Interconnection applications)

  • Press the test button on each interconnected smoke alarm, (one at a time) for 15-20 seconds.
  • The smoke alarm itself will sound first within 5 seconds, then ALL other interconnected smoke alarms should sound their alarm within another 15 seconds. (You may need someone’s help to check all other interconnected smoke alarms do sound).
  • Make sure to repeat the test from all the other interconnected smoke alarms. If any alarms do not sound, please follow the attached file “Detailed testing process” for more checks.
  • If all alarms operate when checked from all locations, then your smoke alarm system is working properly.
