It features a built-in 10-year lithium-ion battery that provides continuous power for up to a decade. Equipped with an ultra-reliable photoelectric sensor, the smoke alarm detects smoke from slow-burning, smoldering fires while keeping false alarms to a minimum. A patented smoke entry system further enhances the detector's reliability by providing a direct path to the smoke sensor. The simple twist-lock mounting system installs easily onto a wall or ceiling, while the tamper-resistant locks help prevent removal of the battery to keep the alarm secure. Half as thick as a standard alarm, the smoke detector has a sleek, slim design that blends in seamlessly with most decor.

Then it started beeping so I sent it back. It has no wires, but makes baseless claims about having a 10 year battery inside. Save yourself! **Q: is this a hardwired unit with the 10 year battery backup or does the power come soley from the battery, with no hardwiring at all?** A: No wiring at all, the battery provides 10 years of power. Once it's dead the battery cannot be replaced and you will have to replace the whole unit. **Q: is this detector the same or a newer version of model no. p1210 ?** A: I can say for sure that when one of my P1210 alarms started going off continuously for no reason after about a year of use, in early 2018 First Alert warranty service replaced it with one of these PR710 models. Whether that's because the P1210 is manufactured specifically for Costco and PR710 is the general model, or because the P1210 has been discontinued and replaced by the PR710, I'm not sure, but my guess is the PR710 is the newer version and First Alert was using Costco to clear out old stock of the P1210. The only apparent difference is the shape of the test/silence button (they both fit on the same base) so it could be that the electronics inside are identical. **Q: Why can’t ship to my address in los angeles california** A: Thank you for your question. Some California municipalities may require hard-wired smoke alarms, this unit is battery powered. ## Frequently Bought Together - First Alert Slim Photoelectric Smoke Alarm with 10-Year Sealed Battery, PR710, White - First Alert SMCO210, 10-Year Sealed Battery Combination Smoke & Carbon Monoxide Alarm with Slim Profile Design, 1-Pack - First Alert CO710 Carbon Monoxide Detector with 10-Year Battery and Digital Temperature Display , White --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/701783889-first-alert-slim-photoelectric-smoke-alarm-with-10-year-sealed](https://www.desertcart.us/products/701783889-first-alert-slim-photoelectric-smoke-alarm-with-10-year-sealed) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-17*
