No problems here at all! - No problems linking and installing these six smoke detectors, replacing six very old firex detectors, both battery-only and battery-wired units. I've been frustrated for years late in the evening or middle-nighttime with one detector chirping because of a low 9-volt battery. Hopefully, these will indeed last 10 years (but even five years will be satisfactory). Linking one at a time is simple: Out of the box on a convenient table, with units mounted to their bases to be activated, press the button 4 times on one unit, then after it starts flashing (searching), press the button twice on another unit. Repeat for all units. Finally, test the links by holding down the button on any one unit continuously until not only does it start to alarm, but longer until others begin to alarm as well. All linked units begin to sound-off. Mounting was simple to the existing firex base mounts. For battery-only units, the X-sense holes were compatible. For battery-wired units, the firex bases serve as a convenient template for drilling holes in the X-sense bases that match the existing wiring box screws. I never had to open the screws/mollys provided by X-sense. Four units are upstairs, and two units are downstairs, separated by only about 30 feet straightline distance and through at least four drywall/flooring/carpet barriers. Mine was simple, close-distance linking without complications of extensive metal appliances or HVAC ducting. No problems here at all! Review: Reliable 10-year battery smoke detectors - I recently installed these interconnected smoke detectors and I’m extremely satisfied. The 10-year battery life is incredibly convenient, eliminating the need for frequent replacements. They work flawlessly, and when one alarm goes off, all the connected units sound, providing extra safety for the entire home. Installation was straightforward, and the build quality feels solid and reliable. Overall, a high-quality, trustworthy smoke detection system that I would definitely recommend. ## Features - Detection Anywhere: Features wireless interconnection so that if one alarm is triggered, they all go off, and they stay connected using radio frequency with a transmission range over 820 ft (250 m) in the open air - Ready to Use: The multi-pack detectors have already been connected for instant use, and you can connect up to 24 Link+ wireless alarms at a time - Customizable Wireless Network: For a customized network, add new devices to the existing network, or disconnect the devices and create multiple networks - Battery Powered Smoke Alarm: Built with a 10-year sensor and powered by a sealed 10-year lithium battery that doesn’t need to be replaced - Premium Quality Material: This smoke detector is made from an upgraded premium material that is durable, corrosion-resistant, and flame-retardant ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09K4Z262N | | Alarm | Audible | | Best Sellers Rank | #110,092 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #138 in Smoke Alarms | | Brand | X-Sense | | Built-In Media | 1 Γ— User Manual, 3 Γ— Smoke Alarms SD19-W with Sealed 10-Year Lithium Battery, 6 Γ— Screws and Anchor Plugs | | Customer Reviews | 4.4 out of 5 stars 811 Reviews | | Manufacturer | X-Sense Electronics., Ltd. | | Model Number | SD19-W | | Power Source | Battery Powered | | Power source | Battery Powered | | Product Style | RF Interconnected Model | | Style | RF Interconnected Model | | Unit Count | 3 Count | | Unit count | 3 Count | ## Product Details - **Brand:** X-Sense - **Style:** RF Interconnected Model - **Power source:** Battery Powered - **Item weight:** 0.7 Kilograms - **Alarm:** Audible ## Images ![X-Sense 10-Year Battery Wireless Interconnected Smoke Detector Fire Alarm with Over 820 ft Transmission Range, SD19-W, 3-Pack - Image 1](https://m.media-amazon.com/images/I/61zJWQlWq3L.jpg) ![X-Sense 10-Year Battery Wireless Interconnected Smoke Detector Fire Alarm with Over 820 ft Transmission Range, SD19-W, 3-Pack - Image 2](https://m.media-amazon.com/images/I/61hGGlP72eL.jpg) ![X-Sense 10-Year Battery Wireless Interconnected Smoke Detector Fire Alarm with Over 820 ft Transmission Range, SD19-W, 3-Pack - Image 3](https://m.media-amazon.com/images/I/61ogG+tiImL.jpg) ![X-Sense 10-Year Battery Wireless Interconnected Smoke Detector Fire Alarm with Over 820 ft Transmission Range, SD19-W, 3-Pack - Image 4](https://m.media-amazon.com/images/I/61EqhgbHXvL.jpg) ![X-Sense 10-Year Battery Wireless Interconnected Smoke Detector Fire Alarm with Over 820 ft Transmission Range, SD19-W, 3-Pack - Image 5](https://m.media-amazon.com/images/I/619wzwHkUJL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quickly linked and installed to replace old battery-eaters.

The 10-year battery life is incredibly convenient, eliminating the need for frequent replacements. They work flawlessly, and when one alarm goes off, all the connected units sound, providing extra safety for the entire home. Installation was straightforward, and the build quality feels solid and reliable. Overall, a high-quality, trustworthy smoke detection system that I would definitely recommend. ### ⭐⭐⭐⭐⭐ Simple setup, perfect synchronized operation in case smoke is detected. *by S***R on 11 June 2025* These smoke detectors work perfectly! Just as advertised. After setup of all 6, I tested them one at a time with real smoke and they all alarm together. I followed the simple setup instructions and was done setting them up in 5 minutes. The trick is to plug all the detectors into their bases on a table, and do the setup procedure. Putting the base onto the detector activates a switch on the back of the detector to "turn it on". They won't do anything until the bases are put on. After setting them up, then install them throughout the house. ## Frequently Bought Together - X-Sense 10-Year Battery Wireless Interconnected Smoke Detector Fire Alarm with Over 820 ft Transmission Range, SD19-W, 3-Pack - X-Sense Remote Controller RC01 Pro for X-Sense Link+ Wireless Smoke & Carbon Monoxide Detector Alarms (1-Pack) - X-Sense Smoke and Carbon Monoxide Detector Combo, Wireless Interconnected Combination Smoke and Carbon Monoxide Detector with 10-Year Battery, Up to 24 X-Sense Link+ Wireless Alarms, SC01-W, 3-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.id/products/723568267-x-sense-10-year-battery-wireless-interconnected-smoke-detector-fire](https://www.desertcart.id/products/723568267-x-sense-10-year-battery-wireless-interconnected-smoke-detector-fire) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-09-17*
