Review on 🔥 Futuristic 10 Year Heat Alarm: Fireangel HT-630 for Unmatched Safety by Sirious Cavalli

Although I have admitted that I was lied to at first that I thought I needed to install a lithium-ion battery because the description incorrectly says one is required, NO ADDITIONAL BATTERY IS REQUIRED. EMPTY RECTANGULAR INSERT on the back of the device LOOKING LIKE THE BATTERY COMPARTMENT (AS SHOWN IN THE PHOTO), NOTHING! Don't pay attention! The battery is located inside the device, therefore the alarm can only be activated if the device is rolled into a flat back! Attach the flat thin backplate to the wall, screw the device into the flat backplate and you're done. I've been looking for a HEAT alarm for a long time (I have many smoke alarms) but I needed it for a forgetful friend. Who leaves the heat under the pans! A smoke alarm would be too late as the fire had already started, I needed a heat alarm and it works great! The shrill alarm clock draws your attention very effectively. I installed it vertically on a nearby wall near the stove and it works fine. The manufacturer's recommendation is to amend the instructions to better explain the empty chamber and the need to INSTALL the device on a flat back to trigger the alarm. Work!
