Behind every outlet in your home is a small empty space. It's exactly where electrical fires start.
Most people never think about what's inside the wall. FXN-S1 sits inside that space and reacts to heat automatically — no power, no wiring, no app to set up.
You won't see it coming.
Electrical fires don't start with smoke. They start quietly — a loose connection, a stressed wire, a splice that's worked its way loose over the years — heating up inside a small enclosed box behind your wall plate.
There's no light, no smell, and no warning. It can be happening right now, behind an outlet in your bedroom, your kitchen, or your kid's room, and there's simply no way to know.
Behind furniture, running chargers and lamps overnight.
Heavy appliance loads on outlets that were wired decades ago.
The room you'd least want to find out about it in.
Crowded splices that loosen slowly, year after year.
Every point above is a place this risk can start, completely unnoticed.
Heat builds long before you'd ever see smoke.
Loose connections and overloaded circuits generate heat gradually, inside the one place nobody's watching. Here's what changes when FXN-S1 is in there with it:
Millions of sealed microcapsules ride on a thin adhesive pad pressed to the inside wall of the enclosure.
Only the capsules exposed to the developing fault open. The rest stay sealed and keep protecting.
Suppression happens inside the box, in seconds, before the fault ever becomes a house fire.
Fully automatic. Fully passive. Nothing to charge, sync, or maintain.
One sticker. Ten seconds. That's the whole install.
No electrician, no rewiring, no app. Turn off the breaker, peel the backing, press it inside the box for 10 seconds, and you're done. It works quietly in the background for years — you'll probably forget it's even there.
Switch the circuit off and verify the power is actually off before you open anything.
Take off the cover plate to expose the inside of the outlet or switch box.
Peel the backing and press FXN-S1 firmly against the inside of the box for ten seconds.
Reinstall the plate, restore power, and let it work quietly in the background for years.
Count the outlet or switch positions behind each wall plate. Tap a box below to see the math.
Less than a coffee, per outlet you protect.
Compare that to an electrician's service call, a fire damage claim, or the cost of not knowing. It's one of the smallest amounts you'll ever spend on peace of mind.
Protect the outlets you walk by every day.
Twelve stickers. One afternoon. Years of quiet protection you'll never have to think about again.

FAQ & important information
Yes, if you are comfortable turning off the breaker, verifying the power is off, and removing a cover plate. If you cannot safely verify power is off, or the box is crowded or damaged, use a licensed electrician.
A gang is one outlet or switch position. A single outlet box is 1-gang and needs one FXN-S1. A 2-gang box needs two. The 12-pack covers up to 12 gangs.
No. FXN-S1 is fully passive and activates from heat alone, with no power, sensors, wiring, or electronics.
Turn off the circuit and stop using that outlet or switch. Have a licensed electrician inspect and fix the underlying electrical problem, then replace the sticker.
Recommended replacement is 5 years after installation under stated conditions. Check it visually whenever the box is open.
No. FXN-S1 is supplemental, localized protection inside the electrical box. It does not replace smoke alarms, extinguishers, sprinklers, electrical maintenance, or code-required protection.
FXN-S1 provides supplemental, early-stage fire suppression inside enclosed indoor outlet and switch boxes. It does not prevent electrical faults and does not replace proper electrical installation and repair, breakers, AFCI/GFCI protection, smoke alarms, fire extinguishers, sprinklers, or any code-required fire protection. For indoor enclosed boxes only — not for open-air use, damp locations, or spaces where sustained temperatures exceed 149°F (65°C). If you suspect an electrical problem, turn off the circuit and have a licensed electrician find and fix the cause.
