The date on the back of the product is the manufacture date, not the expiration date · A single unit can be installed where previously two were needed · Battery Safeguard ensures the unit cannot be accidentally mounted without batteries installed · Test Reset Button tests alarm circuitry and triggers the voice announcement · Kidde?s smoke alarms and carbon monoxide detectors meet the requirements of Underwriters Laboratories (UL), an independent facility that tests products for compliance with widely-accepted safety standards àWe Offer *FREE* Quick Fast In a Hurry To Your Door Shipping We Ship FREE to the Lower 48 States Only, I Cannot Combine Shipping. *********************** If you are located outside the United States, please contact us before you make a purchase.
