Kidde P3010B 10-Year Battery Smoke Detector

A battery photoelectric smoke alarm that needs no battery changes and switches on when mounted. It senses smoke only, so add separate carbon monoxide protection.

Kidde 10SDR Compact Smoke Detector

A straightforward, no wiring smoke alarm for a single room. Buy it to fill a coverage gap, not to build a whole home interconnected system.

Kidde 20SDR Battery Smoke Detector

A solid standard-battery alarm with the hush button its sealed sibling lacks. Pick the 20SD10 instead if avoiding battery changes matters more than the hush feature.

Kidde Pi9010 Dual Sensor Smoke Alarm

A battery powered smoke alarm that combines photoelectric and ionization sensing for both smoldering and flaming fires. The replaceable battery needs regular changes, and it does not detect carbon monoxide.

First Alert SMICO100-AC Hardwired Smoke and CO Detector

A basic hardwired combo alarm for homes replacing First Alert units on existing wiring. The listing is thin: no interconnect, battery type, voice or certification details.

Kidde P3010H Worry-Free Hallway Smoke Alarm

A sealed battery smoke alarm for hallways that lights the path when it sounds. The listing gives no sensor type, size or mounting details.

Universal Security Instruments MI106S Hardwired Smoke Alarm

Kidde Worry-Free Smoke and CO Alarm with Voice 2 Pack

A battery combination smoke and carbon monoxide alarm with voice warnings and no battery changes. No interconnect is described, and the item count conflicts.

USI AMI1061SB Hardwired Smoke and Fire Alarm

A hardwired smoke and fire alarm with long-life battery backup, suited to replacing an existing wired unit. The listing is very thin, so check sensing and interconnect details with USI before buying.

Kidde KN-COPP-3 Plug-In Carbon Monoxide Detector

A straightforward plug-in CO detector with a digital readout and battery backup, well suited to a single room near an outlet rather than a whole-home interconnected system.

First Alert Smoke Alarm SA521CN-3ST

Kidde Hardwired Smoke Detector 20SA10, 2-Pack

A two-pack of hardwired photoelectric smoke alarms with sealed ten-year battery backup and interconnect for whole-home coverage. They detect smoke only, so carbon monoxide needs a separate alarm.

First Alert Hardwired Smoke Alarm SMI105-AC

A hardwired smoke alarm with a long-life backup battery that links to other compatible alarms. It detects smoke only, so pair it with a CO alarm.

First Alert SMI105-AC Hardwire Smoke Alarm 10-Year Battery

A solid hardwired replacement for an interconnected smoke alarm circuit, with sensing tuned to cut down on cooking-related false alarms.

X-Sense SD19-W Interconnected Smoke Detector

First Alert HD6135FB Hardwired Heat Alarm

A smart heat alarm for crawl spaces, laundry rooms and garages, combining fixed temperature and rate-of-rise sensing with remote muting. It needs hardwiring, and the warranty term is not stated.

First Alert SMCO100V-AC Hardwire Smoke and CO Alarm with Voice

A two-function hardwired alarm worth considering when replacing an aging hardwired smoke-only unit where CO coverage is also wanted in that spot.

First Alert SMICO110 10-Year Smoke and CO Alarm

A low-maintenance 2-in-1 smoke and CO alarm for anyone who wants both hazards covered by a single sealed unit.

X-Sense SC06 Smoke and Carbon Monoxide Alarm

A capable two in one alarm with a sealed 10 year battery that most reviewers found easy to install and reliable, though a couple of buyers hit a dead unit out of the box, so it is worth testing right after installing.

Kidde P4010ACS-WF Smart WiFi Smoke Detector

A hardwired smart smoke alarm with phone alerts, a voice warning and a battery backup that lasts its life. Its carbon monoxide sensing is unclear, so plan a separate CO alarm.

Kidde 20SAR-W Hardwired Smart Smoke Detector

A smart upgrade for homes with Kidde hardwired alarms, adding phone alerts and remote hush. It detects smoke only and needs existing house wiring.

First Alert SMI100RV RV Smoke Alarm

A small battery smoke alarm approved for recreational vehicles, with a locking pin so the battery stays in. It covers smoke only and the listing does not say which battery it takes.
