Which FireXNull product is right for my equipment?
Choose by what you are protecting. FXN-S1 is for compatible indoor outlet and switch boxes. FXN Sticker and FXN Rope are sized by enclosure volume for compatible panels and cabinets. FXN Tape wraps individual connections and terminals. If you are unsure, request an engineering review.
How do I size a sticker or rope?
Sizing is based on internal enclosure volume. Each product page and the current Technical Data Sheet list model ranges. If an enclosure falls between two models, select the next larger model. Enclosures with vents or forced cooling need an application review.
How often should products be inspected or replaced?
Inspect periodically during normal equipment servicing. Products are single use and must be replaced after any activation. The recommended replacement is 5 years after installation.
Where can I buy FireXNull products?
On this site and through channels including The Home Depot, Lowe's, Grainger and DigiKey. Availability varies by product and channel. For larger quantities, contact our team.
Do FireXNull products replace sprinklers or code-required systems?
No. FireXNull products provide supplemental, localized protection inside compatible enclosures. They do not replace code-required detection, suppression or electrical protection, and they are not UL Listed or FM Approved as fire suppression products.
