Kidde i4618 Ionization hard-wired smoke detector with battery backup


I purchased a pair of these smoke detectors to replace some old, hard-wired units that came with my house. They are linked together so that if one goes off, the other one will as well. Installation was a snap and the battery backup is a welcome feature. You can get a pair on Amazon for about $20.

Additional features include:

  • Red LED flashes until reset for quick, clear identification of initiating smoke alarm in interconnected system
  • Visible low battery indicator helps locate chirping unit
  • Front loading battery door makes battery changing simple, power link tab makes installation faster
  • False alarm control quiets unwanted alarms for up to 8 minutes
  • Interconnects with other compatible Firex smoke alarms and heat alarms
