August 2026 update: review First Alert devices by exact model
First Alert is best known for smoke and carbon-monoxide alarms, but the name has also appeared on combination alarms, connected products, fire extinguishers, and older camera products. Those categories solve different problems. A smoke alarm is not a burglar alarm, a camera is not a carbon-monoxide detector, and an app alert is not the same thing as a locally sounding life-safety alarm.
This review now uses an exact-model test. Treat older prices, product rankings, and availability notes elsewhere on this page as historical context. Before buying or keeping any device, confirm its model number, current listing, manual, manufacture or replacement date, power source, interconnection method, notification path, and support status. Start with the current First Alert alarm catalog and First Alert support center, then match the information to the label on the device.
What this First Alert review covers
- Smoke alarms: detection type, power, interconnection, local sound, placement, testing, and replacement date.
- Carbon-monoxide alarms: listed use, display or alert behavior, power, placement, and end-of-life signal.
- Combination alarms: how smoke and CO alerts differ, which voice or tone identifies the hazard, and whether every household member can recognize it.
- Connected features: account ownership, phone notifications, Wi-Fi requirements, app permissions, and what continues to work during an internet outage.
- Legacy products: whether the exact model still receives app, firmware, cloud, or replacement support.
This is not a substitute for the device manual, local fire-code requirements, or guidance from your fire authority. Life-safety devices need to be selected, installed, and tested for the actual building.
Use the label, not the brand name, to make the decision
Two devices carrying the same brand can have different sensors, batteries, interconnection methods, app features, and replacement schedules. Record the full model number from the back or side label. Then check the manual and current product page for that exact model.
For every installed alarm, record:
- Exact model and serial number, if present.
- Manufacture date and stated replace-by or end-of-life date.
- Battery type or hardwired power arrangement.
- Whether interconnection is wired, wireless, or absent.
- Which smoke, CO, low-battery, fault, and end-of-life signals it produces.
- Room or level where it is installed.
- Date of the last documented test and the person who performed it.
If the label is missing, unreadable, or inconsistent with the app, stop treating the device as fully verified. Ask First Alert support for the correct manual or replace the unit according to the maker’s guidance and local requirements.
Check the life-safety path before connected features
The core question is whether the alarm detects its listed hazard and produces the required local warning. Phone alerts, voice assistants, dashboards, and remote histories may be useful, but they add dependencies: power, Wi-Fi, internet, account access, phone permissions, and cloud service.
Test the local alarm according to the exact manual and local guidance. Do not use an improvised flame, smoke source, exhaust gas, or another hazardous test. Confirm that occupants can hear and identify the signal from bedrooms and other occupied areas. If alarms are meant to interconnect, verify that the initiating unit and the other units behave as the manual describes.
Then test the connected path separately:
- Trigger only the approved test mode and note whether the app receives the right event.
- Check notification permission, focus mode, battery optimization, and account access on each intended phone.
- Disconnect internet service in a controlled test and document what still sounds locally, what is delayed, and what disappears.
- Restore service and confirm that the device reconnects without an unreported fault.
Do not treat a discontinued camera as a current alarm choice
Older First Alert material may mention cameras or app-based security products. A legacy camera should be judged on its current operating state: whether the app can still be installed, whether account recovery works, whether firmware and cloud services remain available, and whether clips can be exported before service changes. A working video feed does not prove that security patches, notifications, or recordings are dependable.
If a legacy camera fails those checks, isolate it from sensitive networks, export needed footage, remove access for former users, and replace it through a planned migration. Compare a replacement camera or alarm system by its current functions, not by an old retail price. Keep life-safety coverage separate from burglar-alarm coverage, response, privacy, and recurring cost.
First Alert versus a connected smoke-and-CO alternative
Brand-level comparisons hide the details that matter. Compare one exact First Alert model against one exact alternative with the same intended use. For examples of the connected-alarm category, see Kidde vs Google Nest Protect and X-Sense vs Google Nest Protect. Do not assume that a feature described for one model applies to another.
Use the same worksheet for both products:
- Required listing and approved installation location.
- Smoke and CO detection functions included in that model.
- Battery, hardwired power, and backup-power requirements.
- Interconnection with the existing alarms in the home.
- Local tones, voice prompts, visual indicators, and accessibility needs.
- App, account, Wi-Fi, internet, and cloud dependencies.
- Replacement interval, support path, and total number of units needed.
Run a 60-minute First Alert acceptance test
Complete this test after installation, after a router or account change, and when responsibility for the home changes. Use only the procedures allowed by the exact manual.
- Inventory — 10 minutes: photograph each label and record model, date, location, power, and interconnection.
- Local test — 15 minutes: use the approved test control and confirm that occupants can hear and identify the warning.
- Interconnection — 10 minutes: where supported, verify the expected response from the other linked alarms.
- Phone path — 10 minutes: check app access and notification delivery on every intended phone without assuming the phone alert replaces the local alarm.
- Outage behavior — 10 minutes: document what happens during a controlled internet interruption and after service returns.
- Handoff — 5 minutes: store manuals, replacement dates, support details, and the test record where another responsible adult can find them.
Any failed or ambiguous result is a stop sign. Resolve it with the manual, First Alert support, a qualified professional, or the relevant local authority before relying on the device.
Bottom line
First Alert can be a sensible starting point for smoke, CO, and other life-safety devices, but the brand alone does not establish fit. Buy and maintain by exact model. Confirm the current listing and manual, test the local warning first, document connected dependencies, and replace unsupported or unverified hardware through a controlled plan.
First Alert Security Products: From Legacy DVRs to Smart Smoke Detectors
First Alert has been a household name in home safety since 1958. But here’s what most people don’t realize: First Alert doesn’t make security systems — they make safety products (smoke detectors, CO alarms, fire extinguishers, safes) and a few standalone cameras. If you’re looking for a complete home security system, you’re in the wrong aisle.
This review covers what First Alert actually offers in 2026, what they discontinued, and what to buy instead.
First Alert at a Glance (2026)
| Category | Status | Our Take |
|---|---|---|
| Smart Smoke/CO Detectors | ✅ Active — Onelink line | Good products, especially Onelink Safe & Sound |
| Traditional Smoke/CO | ✅ Active — market leader | Reliable, affordable, available everywhere |
| Fire Extinguishers | ✅ Active | Household standard |
| Fireproof Safes | ✅ Active — under SentrySafe brand (same parent) | Decent budget options |
| Security Cameras (D-575, etc.) | ❌ Discontinued | Don’t buy — no support, no app, outdated |
| DVR Systems | ❌ Discontinued | Replaced by modern cloud cameras |
| Home Security Systems | ❌ Never offered | Not their business — use Abode or Ring instead |
What First Alert Does Well: Smart Smoke & CO Detectors
First Alert’s Onelink line is where they actually compete in 2026. These are genuinely good products:
Onelink Safe & Sound
- Smoke + CO detection with voice alerts (tells you the threat AND location)
- Built-in premium speaker (AirPlay 2 compatible)
- Apple HomeKit & Alexa integration
- 10-year sealed battery backup
- Price: ~$119
Onelink Smoke & CO Detector
- Photoelectric smoke + electrochemical CO sensing
- Apple HomeKit compatible
- Phone alerts when you’re away
- 10-year battery
- Price: ~$99
How They Compare to Nest Protect
| Feature | First Alert Onelink Safe & Sound | Nest Protect | Kidde Smart Detect |
|---|---|---|---|
| Price | $119 | $129 | $45 |
| Smoke Detection | Photoelectric | Split-spectrum | Photoelectric |
| CO Detection | ✅ | ✅ | ✅ |
| Voice Alerts | ✅ Location-specific | ✅ Location-specific | ✅ Basic |
| Phone Alerts | ✅ | ✅ | ✅ |
| HomeKit | ✅ | ❌ | ❌ |
| Alexa/Google | ✅ Alexa only | ✅ Google only | ✅ Both |
| Built-in Speaker | ✅ Premium AirPlay | ❌ | ❌ |
| Pathlight (night light) | ❌ | ✅ | ❌ |
| Self-Test | ✅ Monthly | ✅ Nightly | ✅ Monthly |
| Battery Life | 10 years | Wired + backup | 10 years |
Verdict: The Onelink Safe & Sound wins for Apple/HomeKit households (it’s one of the best HomeKit smoke detectors). Nest Protect wins for Google households with its superior split-spectrum sensing and Pathlight feature.
The D-575 and Legacy Cameras: Don’t Buy These
If you found this page searching for the First Alert D-575 or any First Alert camera system, here’s the reality:
- The D-575 digital wireless security system was discontinued years ago
- No firmware updates, no app support, no cloud integration
- Uses outdated 2.4GHz wireless that’s easily interfered with
- No AI detection, no person/vehicle alerts, no integration with anything
- Resolution was 640×480 — worse than a 2010 smartphone
If you still own one: it served its time. Here’s what to replace it with:
Best Camera Replacements for First Alert Systems
| If You Need… | Get This | Price | Why |
|---|---|---|---|
| Budget indoor camera | Wyze Cam v4 | $35 | Color night vision, person detection, local + cloud storage |
| Indoor + security system | Abode Cam 2 | $35 | Integrates with Abode security system, motion zones, 2-way audio |
| Outdoor surveillance | Ring Stick Up Cam | $99 | Weather-proof, battery or wired, Ring ecosystem |
| Full NVR system (like D-575) | Reolink RLK8-410B4 | $280 | 4 cameras + NVR, 4K, PoE, no subscription |
| Complete security system | Abode Smart Security Kit | $199 | Full alarm system + cameras + sensors + no contract |
Cameras vs. Security Systems: The Critical Distinction
This is the biggest mistake people make when shopping for “First Alert security”: cameras record crimes, security systems prevent them.
| Feature | Cameras Only (First Alert, Wyze, etc.) | Security System (Abode, Ring Alarm, etc.) |
|---|---|---|
| Door/window sensors | ❌ | ✅ |
| Siren | ❌ (some cameras have small speakers) | ✅ 105dB+ |
| Professional monitoring | ❌ | ✅ Optional |
| Police dispatch | ❌ | ✅ With monitoring |
| Geofencing auto-arm | ❌ | ✅ |
| Glass break detection | ❌ | ✅ |
| Smoke/CO monitoring | ❌ | ✅ (integrates with detectors) |
| Insurance discount | Usually no | 5–20% discount |
| Burglar deterrent level | Low–Medium | High |
Bottom line: If you’re upgrading from a First Alert camera system, consider a complete security system like Abode ($199, no contract, free self-monitoring) rather than just replacing cameras. You’ll get actual protection instead of just footage of things going wrong.
Monitored Smoke & CO Detection: The Real Upgrade
First Alert makes great standalone detectors, but they only alert you locally. If you want monitored fire/CO detection — where a monitoring center calls the fire department even when you’re not home — you need a security system with compatible smoke sensors:
| System | Smoke/CO Sensor | Monitoring Cost | Fire Dispatch |
|---|---|---|---|
| Abode | Abode Smoke Alarm Monitor ($30) | $6–$20/mo | ✅ On Standard+ plans |
| Ring | First Alert Z-Wave ($40) | $20/mo | ✅ Ring Protect Pro |
| SimpliSafe | SimpliSafe Smoke ($30) | $28/mo | ✅ Fast Protect |
| ADT | ADT Smoke Detector ($100+) | $28–$60/mo | ✅ All plans |
This is the most important upgrade you can make: a smoke detector that actually dispatches help when you’re not home.
The First Alert / Resideo / BRK Corporate Confusion
If you’ve tried shopping for First Alert products, you’ve probably noticed confusing branding. Here’s the corporate family tree:
- Resideo Technologies — Parent company (spun off from Honeywell in 2018)
- First Alert — Consumer brand for smoke detectors, CO alarms, safety products
- BRK Electronics — Same company as First Alert (manufacturing brand)
- Onelink — First Alert’s smart product line
- SentrySafe — Fireproof safes brand (same parent company)
When buying: First Alert, BRK, and Onelink are all the same company. The Onelink products are the smart/connected versions of their traditional safety products.
Our Recommendation
For smoke/CO detection: First Alert Onelink products are genuinely good — especially for HomeKit users. They’re our #2 pick behind Nest Protect.
For security cameras: Skip First Alert entirely. Get modern cameras from Abode, Ring, Nest, or Wyze.
For a complete security system: First Alert doesn’t make one. Get Abode Smart Security Kit ($199) — it can integrate with First Alert Z-Wave smoke detectors for the best of both worlds.
Frequently Asked Questions
Does First Alert make a home security system?
No. First Alert makes smoke detectors, CO alarms, fire extinguishers, safes, and some standalone cameras — but not complete security systems. For a security system, look at Abode, Ring, or SimpliSafe.
Is the First Alert D-575 still worth buying?
No. The D-575 digital wireless recording system has been discontinued with no software updates, no cloud support, and outdated 640×480 resolution. Replace it with a modern Wi-Fi camera or full security system.
What’s the best First Alert smoke detector?
The First Alert Onelink Safe & Sound ($119) is the best for Apple/HomeKit homes. For Google homes, Nest Protect ($129) is better. For budget, the standard First Alert SC7010BV hardwired combo ($35) is reliable.
Can First Alert detectors work with a security system?
Yes — First Alert makes Z-Wave compatible smoke/CO detectors that integrate with Ring, Abode, and other Z-Wave security systems. This gives you monitored fire detection with professional dispatch. The First Alert ZCOMBO-G is the most popular Z-Wave model.
Is First Alert the same as BRK?
Yes. BRK Electronics and First Alert are the same company — both owned by Resideo Technologies (formerly part of Honeywell). BRK is the manufacturing brand; First Alert is the consumer brand. Products are identical.
What happened to First Alert cameras?
First Alert discontinued their camera products (D-575, indoor cameras) several years ago. They never invested in the cloud infrastructure or AI detection needed to compete with Ring, Nest, and modern camera brands. Their focus returned to their core strength: fire safety products.

Related Legacy Alarm Brand Comparisons
June 2026 buyer update: life-safety devices are not a full alarm system
First Alert is strongest for smoke, carbon monoxide, fire safety, and basic life-safety coverage. That makes it useful in almost every home, but it should not be treated as a replacement for an intrusion alarm with door sensors, siren behavior, cellular backup, and emergency dispatch.
- Choose First Alert for smoke, CO, fire-safety, and basic hazard coverage.
- Add a security system when the property also needs burglary alerts, entry sensors, app arming, and monitoring.
- Check compatibility before assuming life-safety devices will trigger the same routines as a full alarm platform.

William is a tech buff and former corporate security officer turned cybercrime analyst. Computers have few secrets left for him, but home security and alarm systems… Well, those have plenty of secrets for their users, which William is now uncovering and explaining. His articles on home security helped many people take the matter seriously, invest in highly performing systems, and avoid becoming victims of burglaries.
Ken Speert says
I wouldn’t recommend buying a first alert smartbridge system at all! I’ve had one for less than 2 years and both cameras at the same time stopped working,screen went black and the tecs at their company says they stopped making the system? their tecs says they are only warrentied for 1 year and couldn’t help me with any solutions for getting them working again. Go to another company who will help and back their product.
Larry Cole says
Yeah it may be a great nuisance because it blows off at almost every motion, the motion detector and glass break detector is super sensitive and one can get alerted over such actions very quickly. The sensor had saved my house from been burgled on two occasions and it’s been helpful.
Frank Dodds says
Good summary of the Digital Wireless Security System. I have one thing to add about the SD Card funcitonality. There are some SD cards that do have larger amounts of space, for example, you can get one that has over 32 gigs of space. So that should be enough space for the average family.
