Pros and cons

Pros

Backup battery is specified as replaceable, providing a stated secondary power source during outages.
The interconnection claim can be useful for installations where compatible hardwired detectors need to sound together.
Test/silence controls and a stated low-battery mute function offer on-device controls.

Cons

This is not presented as a standalone wireless alarm. The listing describes hardwired power and wired interconnection, so installation depends on a suitable hardwired setup.

What to know before buying

Listing details to confirm

The listing is contradictory about power and quantity: its title describes a hardwired, 10-pack alarm with a 9V backup, while the details call the power source “Battery Powered” and say “Number of Items” is 1. Confirm the selected listing’s actual pack contents and power arrangement before purchase. Its UL 217 10th Edition compliance and sensor performance are manufacturer claims, not independently verified here.

Who is it for?

A good fit for

Households with compatible hardwired alarm wiring that want photoelectric smoke detection and a replaceable backup battery.
Buyers considering coordinated alerts across a hardwired system, subject to confirming compatibility with their existing detectors.

Less suited to

Installations without the appropriate hardwired power and interconnection setup.
Buyers seeking a clearly confirmed 10-unit package without first verifying the selected listing's quantity.

Aggregate ratings are mostly five-star, with some four- and three-star ratings in a limited sample. Without review details, this does not identify specific strengths or problems. For a hardwired alarm with a stated backup battery, the unresolved power and package-quantity details matter more to purchase planning than the aggregate rating alone.

Frequently asked questions

Does this alarm have both hardwired power and a backup battery?

The feature text describes 120V AC hardwired power and a replaceable 9V backup battery. However, the details list its power source as “Battery Powered,” so confirm the selected model's power arrangement before buying.

Can it interconnect with other smoke alarms?

The manufacturer claims hardwired interconnection with up to 12 smoke detectors. The listing does not establish compatibility with a particular existing alarm system.

The listing describes a test/silence button, an audible alarm, a flashing red LED and a 10-hour mute for a low-battery chirp.
