Hey there,

I had this problem, do you live in a apartment block? If so, it is most likely connected to a main system, but the individual alarms still have 9v batteries in them to protect against power cuts, this battery is running low and needs replacing Or you can do what I did and just rip them off the ceiling in anger.

Why do smoke detectors make a beeping noise when the electric goes off they are not hooked to any electric?

When the electricity goes out, a smoke detector may make a final beep as it's capacitor is discharged, as a warning. If the smoke detector has a battery backup, some detectors will beep just to let you know the power is off, and some other units will only beep when the power is off AND the battery is low. Usually there is a legend on the back of the unit that will tell you what the different beeps mean.


Will a short circuit cause smoke detectors to beep after resetting the circuit breaker?

If your smoke detector is bleeping you have a serious risk of fire and the circuit breaker must not be reset until the fault that caused it to trip is investigated.


Can you change a hard wired smoke detector with the electric on?

It is not safe to change a hard-wired smoke detector with the electricity on. Turn off the circuit breaker for the smoke detector before attempting any replacement to avoid the risk of electric shock. It's always best to follow safety protocols when working with electrical components.


Why does my smoke detector beep intermittenly with a brand new battery on Is there a smoke detector that does not beep intermittenlybut has a light indicator for battery operation?

More than likely the cool temperature is causing a marginally good battery to fail the automated battery test. This test applies a brief resistive load to the battery that simulates the power required to sound an alarm. If the voltage falls below a predetermined level, an audible chirp is generated to indicate battery replacement is needed. Cool temperatures affect the battery chemistry in such a way that the voltage will be lower during this test. As a side note, use of lithium batteries in a unit designed for alkaline batteries will exacerbate this problem.


What is the branch of science that compares man made with biosystems?

Biomimicry is the branch of science that compares man-made systems with biosystems in order to design innovative solutions inspired by nature. It involves studying natural processes, structures, and systems to create sustainable and efficient technologies and products.
