Function

• Smoke alarms are typically installed in sleeping areas and hallways, as well as on each level of a home. The hard-wired type of alarm is installed within the electrical system of the home, allowing interconnection between all the units. If one unit detects smoke, they will all ring out their alarms to notify those in the building.
  
  

Features

• Different brands utilize different wiring and programming within each unit, so interconnection between varying units cannot be possible. Installing units in this way can result in alarm failure or false notifications.
  
  

Considerations

• The Simsbury Volunteer Fire Company suggests having a professional install hard-wired interconnection smoke alarms. This ensures proper functioning and electrical safety for an overall reliable system.
