About this item

The First Alert sc-9120b hardwired combination smoke and carbon monoxide alarm uses electrochemical Co sensing technology and ionization sensor for smoke detection. This hardwired dual Co smoke alarm can be connected to other compatible BRK or First Alert hardwired Co smoke detectors within a single-family residence.

The latching alarm indicator automatically identifies which unit initiated the alarm-even after the conditions that set off the alarm have subsided. Using a 9-volt backup battery, the smoke and carbon monoxide detector can function even in the event of a power outage. Additionally, the Co smoke alarm features a single test and silence button, as well as indicator lights that let you know whether the danger is smoke or carbon monoxide.

The tamper-resistant locking brackets and universal mounting brackets make installation easy. Faster turnarounds on job sites with the easy-to-install, most-trusted alarms in home safety.

Common questions

AUTHENTICITYIs this the maker's own product?

Yes. Every product is bought new in the USA from the brand or an established US grocer, and if one is ever found not to be genuine, we refund you in full.

DELIVERYHow long does delivery take?

3 to 4 days door to door for this item, including the time we take to place your order with the brand or retailer. Every parcel travels with a carrier tracking number.

PRICINGWhat does the price include?

Nothing is added at checkout: there is no shipping charge. Every price is for the whole package, never a cost per serving.

ALLERGENSWhere are the ingredients and allergens?

We show the ingredients and allergen statement the maker publishes. Recipes change, so the label on the package you receive always governs: read it before you open or eat anything.

RETURNSWhat if it arrives damaged or past its date?

Email photographs to hello@kitchenspread.com within 7 days of delivery and we refund the full amount or send a replacement at no cost. Food cannot be resold once delivered, so change-of-mind returns cannot be accepted.
