Model number
i12020

The Kidde i12020 is a basic 120V AC hardwired ionization smoke alarm with a large mounting base and tamper-resist feature. A single button operates both Hush and test functions. The pre-stripped wiring harness with tinned strands simplifies installation. This is a legacy model without battery backup — Kidde recommends upgrading to a model with AA backup battery for improved reliability during power outages.

§ FAQ

Does the i12020 have battery backup?

No. The i12020 does not have battery backup. If your home experiences a power outage, the alarm will not function. Kidde recommends upgrading to a model with AA battery backup such as the 20SAR for continued protection during outages.

Does the i12020 support interconnect?

No. The i12020 is a standalone hardwired alarm without interconnect capability. For interconnected whole-home protection, consider the i12040 or the newer Kidde 20SAR DETECT-line models.

What does the tamper-resist feature do?

The tamper-resist feature on the i12020 helps prevent unauthorized removal of the alarm from its mounting bracket. This is useful in rental properties or any setting where tampering is a concern.

How do I install the i12020?

The i12020 connects to your home 120V AC wiring using the included pre-stripped wiring harness. Mount to the ceiling using the large mounting base, connect the wires, and snap the alarm onto the bracket. Test after installation.

What alarm replaced the i12020?

The i12020 has been discontinued. Kidde recommends the 20SAR as a current replacement, offering improved DETECT-line photoelectric sensing, AA battery backup, and hardwired interconnect capability.
