I have a nightlight in my hall where I want to place this unit. Thanks** A: No it will fit in the bottom leaving the top for your night light **Q: can it detect levels of 20,30 or 40 ppm of CO? I know alot can only detect 70 ppm of CO or above...but I'm concerned of a small CO leak of below 70.** A: This unit probably detects CO at less than 30 ppm, but is not allowed to display that level unless a button is pushed. In this case, the peak level the alarm detected since last reset is what will show, not the current ambient level. From 30 to 70 ppm, the display can show the ambient level, but the alarm will not sound until it's been in that range for 30 days, as mentioned. At 70 ppm, the alarm is not to sound for at least an hour, and no more than 4 hours. That's UL requirements, which most codes across the US adhere to. **Q: Why would anyone buy a 2-pack for $75.23 when they can buy two 1-packs for $59.94?** A: I'm going out on a limb here but a two pack includes two detectors for 75.23 a single is 59.94. So if you want two of them you can pay 75.23 or 120.00 I have no idea why someone would spent 75.00 when they could spend 120 for the same items. Hopefully someone will be able to answer this question. **Q: Does this alarm work when using an extension cord or must it be plugged directly into a wall outlet?** A: The instruction booklet that came with my First Alert carbon monoxide alarm (I do not know if I bought a "model C0615" -- my alarm has NO identifying alpha-numeric) informs me that there IS an extension cord already on the back of the alarm; it also tells how to access it. I unplugged my alarm from the outlet, turned it back-side-up and true enough the 2 pronged plug you use to plug it into the electrical outlet is part attached to a lightweight extension cord that I would estimate to be about 4 or 5 feet long. The instruction booklet says that is for use by those who want to remain standing and look at the alarm "face-to-face." Hope this helps, Fat. ## Frequently Bought Together - FIRST ALERT Dual-Power Plug-In Carbon Monoxide Detector with Battery Backup and Digital Display, CO615 , White, Pack of 3 - FIRST ALERT Dual Sensor Smoke and Fire Alarm, SA3210 , White - First Alert BRK 3120B Hardwired Photoelectric and Ionization Smoke Alarm with Battery Backup, Dual Sensing Smoke Alarm, 1-Pack --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/39066046-first-alertdual-power-plug-in-carbon-monoxide-detector-with-battery](https://www.desertcart.co.th/products/39066046-first-alertdual-power-plug-in-carbon-monoxide-detector-with-battery) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-23*
