This does depend how sensitive your alarm is though. Some smoke detectors are that sensitive that even a steam iron will set it off. **Q: Is it jog proof and will it read cd-r's?** A: It’s a smoke detector that fits securely to the house ceiling with no movement. Nothing to do with a cd-r involved in installation. **Q: Hi, will this work with 5GHz / full fibre broadband Wifi?** A: I don’t think so, as to my knowledge it’s not Wi-Fi enabled ## Frequently Bought Together - FireAngel Optical Smoke Alarm 2-Pack - FA6620 10-Year Battery Smoke Alarms for Home with Test/Silence Button - Replacement for FireAngel ST-622/ST-620 - Early Smoke Detector Fire Alarm - White - FireAngel Carbon Monoxide Alarm and Detector - FA6813 10-Year Sensor Life CO Alarm for Home with AA Batteries - Travel, Portable Carbon Monoxide Detector - CO Detector Monitor with Test Button - FireAngel Heat Alarm with 10 Year Sealed For Life Battery, FA6720-R (HT-630 replacement, new gen), 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.kg/products/422676184-optical-smoke-alarm-2-pack-fa6620-10-year-battery-smoke](https://www.desertcart.kg/products/422676184-optical-smoke-alarm-2-pack-fa6620-10-year-battery-smoke) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-09-12*
