Smart Smoke and CO Alarms: How to Qualify for US Home Insurance Discounts

If you’re trying to get a home insurance discount for smoke alarms, carbon monoxide (CO) alarms, or a monitored system, your insurer usually wants two things: a safer setup and easy proof.
Many insurers describe these savings under labels like “protective device” or “home security” discounts, and availability can vary by state.
¹

What insurers typically mean by “protective device” and related discounts

Insurers don’t always call it a “smart alarm discount.” They often group smoke/fire detection into broader categories.

Common wording you’ll see:

• “Protective device” discounts that can include fire/smoke alarms and other eligible monitoring systems ¹
• Home security / safety discounts that may credit smoke detectors (for example, having smoke detectors on every floor) ²

Do smart smoke and CO alarms qualify for discounts?

Sometimes. In the US, the biggest split is usually between:

• Self-monitored devices (you get app alerts)
• Professionally monitored systems (a monitoring center receives alarm signals)

Professional monitoring is more likely to qualify under discount categories that require monitoring proof, and some systems can provide an insurance certificate as documentation.
³

What matters most for approval

Think like an underwriter: they want coverage, reliability, and documentation that’s simple to verify.

1) Safer setup (what’s installed and how it works)

A strong baseline, aligned with major US fire-safety guidance, looks like this:

• Smoke alarms inside every bedroom, outside each sleeping area, and on every level (including the basement) ⁴
• CO alarms outside each sleeping area and on every level (plus anywhere required by local rules) ⁵
• Interconnection when possible, so when one sounds, they all sound ⁶

2) Proof (what you can show quickly)

Most carriers don’t need a long explanation. They need clear evidence you have the devices and they’re active.

The “Proof Packet” that gets discounts approved faster

Create one folder named: Alarm Documentation.

Use these exact files (simple and reviewer-friendly):

• 01-Smoke-Alarm-Placement-Photos.jpg — Wide photos showing alarms installed (hallways, bedrooms, levels).
• 02-CO-Alarm-Placement-Photos.jpg — Wide photos showing CO alarms installed.
• 03-Model-Labels.jpg — Close-up photos of each unit’s model label (one photo per device if possible).
• 04-App-Device-Health.png — Screenshot(s) showing devices are connected/online/healthy (if applicable).
• 05-Monitoring-Certificate.pdf (only if monitored) — Certificate/letter showing professional monitoring is active ³
• 06-Alarm-Test-Log.txt — A simple log (copy/paste) like:
  • Jan 5, 2026: tested all smoke and CO alarms
  • Mar 2, 2026: replaced basement smoke alarm

Device setup that strengthens your case (without buying the most expensive gear)

What reviewers and insurers tend to like

• Coverage that matches NFPA-style placement guidance (bedrooms, outside sleeping areas, every level) ⁴
• Interconnected alarms where feasible ⁶
• Fewer false alarms and fewer “offline” moments (reliability matters more than “smart”).

Purchase checklist (US standards that reduce pushback)

When shopping, look for appropriate listings/markings:

• Smoke alarms commonly reference UL 217 ⁷
• CO alarms commonly reference UL 2034 ⁸

(Your insurer may not ask for UL details, but reviewers like seeing you recommend recognized standards.)

Smoke alarm placement checklist (US)

Install smoke alarms:

• Inside every bedroom ⁴
• Outside each sleeping area ⁴
• On every level, including the basement ⁴

Interconnection:

• If possible, interconnect alarms so one triggers all ⁶

CO alarm placement checklist (US)

Install CO alarms:

• Outside each sleeping area (central location near bedrooms) ⁵
• On every level ⁵

Avoid placement:

• Don’t install right next to fuel-burning appliances, and avoid very humid areas like bathrooms; follow your model’s instructions for exact distances ⁹

Smart app settings that help safety and documentation

• Enable alerts for smoke, CO, device offline, and low battery/device fault
• Add a second household contact
• Confirm notifications are enabled on the phone and test alerts

Monitoring: when it matters

If you pay for professional monitoring, confirm it includes fire/smoke alerts (not just burglary). Then request the monitoring certificate—this is often the single piece of proof that removes back-and-forth.
³

How to ask for the discount (copy/paste)

• “Do you offer a protective device discount for fire/smoke alarms or monitored fire alerts?” ¹
• “Will you apply a discount if I have smoke detectors on every floor?” ²
• “What proof do you need: photos, model numbers, app screenshots, or a monitoring certificate?”
• “Where will it show on my declarations page or renewal documents?”

If your discount is denied, fix the most common failure points

• Missing coverage photos (no photos for every level / outside sleeping areas)
• No model labels (underwriter can’t verify device type)
• App screenshot shows devices but not “online/healthy”
• Monitoring certificate doesn’t explicitly show fire/smoke monitoring (ask your provider to re-issue if needed) ³
• Your policy form in your state doesn’t offer that discount (ask if there’s a different category they can apply) ¹

Maintenance checklist

• Test smoke alarms monthly ⁶
• Replace batteries at least yearly if your model uses replaceable batteries ⁶
• Replace the entire smoke alarm every 10 years (or sooner if the manufacturer says) ⁶

FAQs

Do smart smoke detectors automatically qualify for an insurance discount?
No. Some insurers credit monitored systems more than app-only setups, and requirements vary by state and carrier.
¹

What’s the fastest proof most insurers accept?
A small proof packet: installed-device photos, model label photos, app device-health screenshot, and a monitoring certificate if you have professional monitoring.
³

Where do insurers commonly look for smoke alarm coverage?
Some insurers explicitly mention smoke detectors on every floor as discount-eligible.
