also, does it work to preserve a flower? i found a pretty flower outside and i was wondering if it would harden and make it shiny. is it sold at walmart or micheals? like specific stores please
Some are also supplied by the mains, but that would mean it wouldn't need the batteryhmmm strange. Perhaps it has a smaller battery in it to create a beep when the larger main source battery has been removed, to annoy you and force you to replace the battery quick.
it beeps like that because it is connected to the wiring that goes through the house. Detectors are manufactured to have a small power conduit installed. Once you change the batteries o remove them the beep is more frequent as it is alerting you to the fact that you need to add batteries. Add them then push the test button you should be good.
kind of reminds me of the 2nd predator movie . they discovered the predator was using infrared imaging to detect his prey. so they wore suits designed to mask their heat signature . but the predator did detect something and switched views and saw them as cooler than their environment .he killed them. if you block your heat you still interrupt the flow of air molecules and sooner or later you will be spotted.
It's made to do that, with an internal reserve power source. Would you rather have a smoke detector that sits quietly with dead batteries? Solution: Put in new batteriestoday!
To let you know the battery is dead so you can replace it. They are designed this way so that you do not have a fire without it going off and then sue the smoke detector company for a bad part.
