Review on 🔥 SITERWELL Smoke Detector, Photoelectric Sensor Smoke Alarm with 9V Battery Included, UL Listed Fire Safety, 10-Year Life Time, Ideal for Kitchen, Home, Hotel - Pack of 4 (Model: GS528A) by Yuan Walsh

We recently bought a warehouse. The first thing I wanted to do was power it up so we could keep the air conditioning on. The second thing I wanted were smoke detectors. Not where most people would put them, but I would feel more confident knowing that we could react quickly if something happened. Although I actually only needed 2 packs, I decided to use 4 packs because we can use the other 2 later. These are standard 9V smoke detectors. Each detector comes with a mounting bracket, 2 screws, 2 anchors and a 9V battery. Installation literally took 5 minutes. Both. The LED light is a great feature. If something happens, you can not only hear, but also see. They have a lifespan of 10 years, which is also standard. I feel a lot better knowing our property is protected.
