Beeping or chirping smoke detectors can be caused by a dead or failing battery, a missing battery or a missing electrical feed. As a first step, please check and replace the battery in your smoke detector. If your smoke detector does not have a side mounted battery compartment you will need to remove the smoke from the ceiling. This can be done by twisting the smoke detector to unlock it from its mounting bracket and firmly pulling the device from the bracket. Please note, that J.
