iGuard vs. FireAvert: Prevention vs. Reaction

Both shut off your stove — but only one acts before a fire can start.

If you’re comparing automatic stove shut-off devices to protect an older parent, a loved one with dementia, or residents in a building you manage, the most important question isn’t which device shuts off the stove — it’s when. iGuard prevents forgotten cooking fires before they begin; FireAvert reacts after a smoke alarm has already sounded, meaning smoke or fire has already developed. Here’s an honest, side-by-side comparison.

The one-line difference: iGuard uses a millimeter-wave radar sensor to detect that no one is attentively in the kitchen and shuts the stove off before any heat, smoke, or flame builds up. FireAvert listens for your smoke alarm and cuts power only after the alarm sounds.

Side-by-side comparison

Feature iGuard FireAvert
Approach to fire safety Proactive — shuts off the stove before a fire starts, triggered by absence of a person in the kitchen Reactive — activates only after the smoke alarm sounds (a fire has already begun)
How it detects danger Millimeter-wave radar — senses whether someone is present near the stove Sound sensor — listens for the smoke-alarm frequency (~3.2 kHz)
Requires a working smoke alarm No — fully independent Yes — completely dependent on a working smoke alarm
Protection if the smoke alarm fails Unaffected NFPA reports smoke alarms are non-functional in ~16% (1 in 6) of home fires
Delay before shut-off Shuts off on detected absence — no fire-stage delay ~30-second delay after the alarm sounds (FireAvert site; manual lists 20s)
False shut-offs from normal cooking smoke No — based on presence, not smoke Possible — e.g. opening the oven while roasting can trip the alarm and cut power
Gas stoves Yes — purpose-built gas model with unburned-gas leak auto-shutoff Yes — but still waits for the smoke alarm; no gas-leak detection
Electric stoves 3-prong, 4-prong, and hardwired 3-prong and 4-prong plug-in
Gas-leak auto-shutoff Yes No
Reset after a shut-off Restore power via the app or the iGuard device — clock and settings retained Reset at the electrical panel (breaker), then reprogram the stove clock (FireAvert spec sheet)
Caregiver remote monitoring & alerts Full — app monitoring, remote shut-off, text/email alerts Limited — text alerts on the higher-priced model; remote action limited to restart
Night-time lockout Yes — configurable by day and hour No
Monthly maintenance None Monthly test with the smoke alarm (user manual)
ADA low-frequency (520 Hz) alarm support N/A — no smoke alarm needed Not evaluated for 520 Hz alarms (spec sheet)
Safety certification QAI Listed, conforms to UL ETL Listed (Intertek), conforms to UL 498A
Price $549 (US) / $699 (CAD) ~$199 ($259 with text alerts)
Where to buy Best Buy, Amazon, Crutchfield, direct Amazon, Lowe’s, Walmart.com, direct

Why “prevention vs. reaction” matters

The root cause of the #1 type of home fire is simple: someone turns on the stove and walks away. iGuard watches for the person, not the fire. FireAvert responds once a smoke alarm sounds — which by definition means smoke or flame is already present. FireAvert’s own Installation & User Guide is candid about this:

“The FireAvert stove shutoff device is not intended to replace the user’s own responsibility and good judgment in preventing fires.”— FireAvert Installation & User Guide, March 2026, General Warnings

By the time a smoke alarm triggers FireAvert, a forgotten-cooking fire is already underway — and cutting power to the burner doesn’t extinguish food, grease, or surrounding material already burning. iGuard shuts the stove off before that point is reached.

The smoke-alarm dependency

FireAvert can’t act without a working smoke alarm. Per the NFPA, smoke alarms are non-functional in roughly 1 in 6 home fires. In those homes, a smoke-alarm-triggered device has nothing to respond to. iGuard’s radar works the moment the stove is on, with no third-party device required.

The 30-second window

FireAvert builds in a delay after the alarm sounds before it cuts power — listed as 20 seconds in the March 2026 manual and marketed as 30 seconds on FireAvert’s site. A real fire grows during that window. iGuard has no fire-stage delay because it acts before the fire, based on the absence of a person.

Less hassle — and no monthly ritual

After an iGuard shut-off, the resident restores power from the app or the device; the clock and settings are retained. FireAvert’s spec sheet lists “resets at the electrical panel” as a feature — a trip to the breaker box and reprogramming the stove clock after every activation, including false ones. FireAvert’s manual also calls for monthly testing with the smoke alarm; iGuard requires no recurring maintenance.

Gas-leak protection FireAvert doesn’t offer

iGuard’s gas model adds automatic shut-off of the gas line when unburned gas is detected. FireAvert has no equivalent capability and, on gas, still waits for the smoke alarm.

Where FireAvert may be a fit. FireAvert is a well-known, lower-cost device (as seen on Shark Tank) and simple to install. If your priority is an inexpensive backup that cuts stove power when a working smoke alarm sounds, FireAvert does that. iGuard is the better choice to prevent the forgotten-cooking fire in the first place, get caregiver alerts, protect against gas leaks, and avoid breaker resets and monthly testing.

Frequently asked questions

Is iGuard a good alternative to FireAvert?

Yes — if you want to prevent forgotten-cooking fires rather than react to them. iGuard shuts the stove off when no one is attentively in the kitchen, before smoke or flame, and works without a smoke alarm. FireAvert only acts after the smoke alarm sounds.

What’s the main difference between iGuard and FireAvert?

The trigger. iGuard uses radar to detect a person’s presence and acts before a fire. FireAvert listens for your smoke alarm and acts after it sounds, with a built-in delay.

Does iGuard need a smoke alarm to work?

No. iGuard operates independently of smoke alarms — its radar sensor activates whenever the stove is on.

Does FireAvert work on gas stoves?

FireAvert offers gas support, but it still depends on the smoke alarm and does not detect unburned gas leaks. iGuard’s gas model adds automatic gas-leak shut-off.

Which is better for someone with dementia or Alzheimer’s?

For dementia care, the goal is to remove the danger automatically without relying on the person to react. iGuard does this proactively and adds caregiver alerts, activity tracking, and a configurable night-time lockout.
