Kidde Firex KF3 Mains Heat Alarm 230V with Battery Backup (New Old Stock)
Finding a matching unit is very hard because Kidde stopped making the Firex KF3 heat alarm. However, a faulty alarm leaves your home unprotected.
Fortunately, we found a small batch of genuine, brand-new, old stock (NOS) Firex KF3 units. These alarms are pristine and completely unused. Furthermore, we ship them in their original factory boxes.
Why Buy New Old Stock (NOS) Firex KF3?
- No Extra Wiring: First, this unit fits directly onto your current baseplate. Consequently, you do not need an electrician to change the mounting plate.
- Keep Your System Safe: Second, this unit links seamlessly with your existing Firex smoke network. Thus, your entire home system stays uniform.
- Perfect for Kitchens: Finally, this alarm triggers at 57°C. So, cooking fumes, steam, and dust will not cause false alarms.
Key Features & Specs:
- Power Source: 230V mains-powered hardwired unit.
- Battery Backup: Standard 9V alkaline battery is inside the box. Note: We recommend a fresh battery due to storage age.
- Interlinked: Connects easily with up to 36 Firex or Kidde alarms.
- Test & Hush: One button lets you check function or quiet a false alarm.
- Condition: New Old Stock (NOS) in sealed box packaging.
Please Note: Kidde discontinued this line. For that reason, the original maker warranty may be expired. However, we fully guarantee that this unit works when it arrives.
