Hi.
We have mains smoke alarms in the shared area of our flats. One was beeping so I took out the capacitor pack (5 x Gold Cap 2.3V 10F) and plugged in a standard 9v battery. This shut the thing up but IS IT SAFE? I have no knowledge of capacitors or how they work but assume they're "one way" and not rechargeable - my concern is that the 9V will blow up or something on receiving current! Forgive my naivete.
I would like to replace the alarm but we have no idea where this thing is wired into, where the fuses are, etc (possibly in the flat of the guy who's never here)
But main question for now really just is - is this safe?
TIA.
