First Alert Sensor Smoke & CO Alarm for $64.99

Costco is offering the First Alert Precision Detection Smoke and Carbon Monoxide Alarm for $64.99. This package includes a 10-year sealed battery and advanced sensing technology with voice and location alerts for danger.

The deal benefits from a $15 manufacturer’s savings valid from September 16 to October 18, 2026. The current price represents a significant value considering the feature set, especially with a 10-year battery that reduces maintenance. Compared to typical prices for comparable 10-year batteries and 2-pack alarms, this is a solid deal and worth attention.

This deal is limited to 10 units per member, so timely purchase may be important for those interested.
