Air sealing wired smoke detectors
I can’t seem to find this answer in the forum.
I’m having connected wired smoke detectors installed in the bedrooms of our 1.5fl 1915 bungalow. Obviously they will be going into the ceiling with small attic above which I have no access to (running a wire from the kneewall). What is the best way to ask the electrician to install it, to keep air leakage to a minimum? He states it will be a 4″ hole x 3 detectors.
