FAQs (1)
Q. I have just purchased a Kidde 4MCO CO alarm. The alarm has been fitted but it is chirping as though it has a faulty battery. Please could you advise?
A.

Before installing the alarm, please ensure the switch on the back of the unit has been moved to the "on" position. The alarm will then recognise the back-up battery is present and working correctly.
