Our verdict

A standalone photoelectric smoke alarm on a sealed ten year battery, installed without wiring. It is listed as a standalone model, so linking several alarms together needs a different product.

Overview

Mounting with two screws and anchor plugs, this photoelectric smoke alarm needs no wiring and runs from a sealed lithium battery. A white ABS housing holds the sensor and an audible alarm.

The sensor type is aimed at kitchen-adjacent false alarms, and a one-button hush and self-test cover silencing and routine checks. Each unit sounds on its own, and the battery is sealed in.

Who it's for

Renters and owners adding a smoke alarm to a hallway or bedroom without touching the wiring get a screw-on unit with a long battery. A buyer who needs alarms that sound together should look for a linked model.

Pros and cons

Pros
  • Sealed long-life battery
  • Hush and self-test button
  • Mounting hardware in the box
Cons
  • Standalone, no linking
  • Battery cannot be swapped
  • Audible alarm only

Performance notes

A photoelectric chamber reacts to smoke particles, which the listing ties to fewer cooking nuisance alarms. The hush button silences a false alarm and the self-test checks the unit on demand. Placement away from the kitchen still cuts nuisance alarms further.
