FireXNull FXN-S1 Automatic Heat-Activated Fire Suppression Stickers for Electrical Outlet and Switch Boxes (12-Pack)

Heat-activated stickers provide supplemental early-stage fire suppression inside enclosed indoor electrical outlet and switch boxes

Includes 12 FXN-S1 stickers for up to 12 compatible gangs when installed as directed, using one sticker per gang

Activates when the temperature at the sticker reaches 248 degrees F plus or minus 9 degrees F, with no batteries, wiring or external power required

Each adhesive-backed sticker measures 0.79 x 0.79 x 0.04 inches (20 x 20 x 1 mm) for compact in-box installation

Peel-and-stick installation: choose a clean, dry, flat upper-left or upper-right interior area in each compatible gang and press firmly for 10 seconds

Turn off power and verify the circuit is de-energized before installation, and keep the sticker clear of wires, terminals and device components

For compatible enclosed indoor outlet and switch boxes in new installations and retrofit projects, with adequate mounting space and clearance; follow the installation guide

Record the installation and replacement dates; replace within five years under specified conditions, or sooner after known or suspected activation, damage, removal or loss of adhesion

Supplements required electrical and fire-safety protection without replacing it, and does not prevent electrical faults or guarantee fire suppression
