🔥 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) Review

It's been difficult to find an inexpensive battery operated photoelectric fire alarm (responsive to smoldering/smoke, not ionization) fire alarm, but this Chinese-made unit seems to do the check to complete. It's not a super good build (but then it costs a little over $10), but it feels reasonable. I set it up in a small workspace with lots of electronics and a bunch of low voltage charge lead-acid batteries. I wanted an extra level of security but didn't want any false alarms due to ionized…

This is NOT a 10 Year Battery Powered Smoke Alarm (which uses a sealed lithium battery to power the device for approximately 10 years). "10 years" in a product name might make you (and me) think you won't change batteries for ten years. However, with this "10 year” smoke alarm, every time it starts beeping you will need to change the battery, maybe a 9V alkaline battery for a few months or a year. According to the National Fire Protection Association (NFPA), smoke detectors should be replaced…

Read other reviews carefully. I didn't do my homework well enough and it's going to cost me money. Maryland passed a law requiring a 10-year lifespan for fire alarms. I have replaced my perfectly good Walmart branded products (which had their batteries changed annually) with these. They cost three times more than the Walmart brand. But they last 10 years, right? NO. Read the fine print. The detector should last 10 years (like any detector in my experience). It came with a battery. The battery…

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…

No fires to date and 18ft ceilings required a tall ladder. I just looked up and he blushed a little and said everything was fine. I had a false alarm instead of the previous smoke detector which was blown off the wall with a broom because it was only silent when the fire was raging and the apartment below me was burning out (the photo would show it but my hands were shaking badly to draw the event. This device detects a flame as well as smoldering ahead of a fire and provides the best early…
