Q. I need to take a chirping Ei150 series smoke alarm off the base to stop the noise. Can I switch the power back on after that or do I have to wait til I received the replacement smoke alarm?
A. You can switch the power back on straight away after removing the alarm. This does not damage the system.
Q. My 13 year old Ei151tl smoke alarm is bleeping, even when I remove it from its base. I think it has a sealed battery.
A. The alarm should chirp for about 5 to 10 minutes and then stop. After that the detector will be dead.
