What’s on the listing

These points come from the merchant listing. OfferLuck does not invent features or scores — only the presentation is tidied.

  1. Linked protection IN every room

    Wirelessly connects ETL-listed alarms across your home; when one detects smoke, all connected alarms sound; helps alert your family faster, especially overnight or in large, multi-level homes

  2. Expandable whole-home protection

    Pairs with up to 18 compatible X-SENSE Link+ alarms, including SC07-W, SC01-W, and SC06-W; build your home safety system over time; use the optional X-SENSE remote to test or hush alarms without reaching up

  3. Sealed 10-YEAR battery

    Built-in lithium battery delivers up to 10 years of power, reducing the need for battery replacements, ladder trips, and late-night low-battery chirps

  4. Photoelectric sensor, easy installation

    Photoelectric sensing helps reduce nuisance alarms from steam and cooking fumes; mounts easily in minutes with the included hardware; ideal for bedrooms, living rooms, hallways, and every level of your home

  5. Self-check, one-button hush & flame-retardant housing

    Automatic self-check monitors the sensor and battery to help ensure reliable operation; one button lets you test the alarm or silence false alarms; flame-retardant housing adds extra peace of mind

Buyer questions

Do you earn a commission if I click Check price?

Yes. Check price uses affiliate links to merchants. OfferLuck may earn a commission at no extra cost to you. Brands cannot buy a better percent-off stamp or sort position. Full disclosure is on the Affiliate disclosure page.

How does OfferLuck sort the deals board?

OfferLuck sorts in-stock deals by verified percent OFF, then by the live price from our last check. A discount appears only when a prior or list price exists and is not inverted. Listings without a verified list price stay off the public board.

When do you show a percent-off?

Only when we have a prior or list price we can stand behind next to the live sale price. If the numbers would require a guess, we omit the percent OFF and keep the row off the public board. The live merchant listing wins if the cart disagrees.

Do you publish star ratings or awards?

No. OfferLuck does not invent star ratings, awards, or lab scores. Images and titles come from the merchant listing. Always confirm price, stock, and fit on the live page before you buy.
