It is very ugly but it's mandatory (the model is thicker and heavier than some models), I do not know if it is effective in smoke but the timing system is very good, I've been to all the floors, c is really very ugly when you have beautiful ceilings to the French, I see that ca I'll end up painting I have the impression of having a deodorant for the cabinets above the head, especially that it is can not hide in a corner (I do not see why we can not paint them if you are careful not to put paint on the buttons) Also this model need many batteries, if you must change batteries every year and you have 5 detectors hello invoice. Prevoir flat screw has the right size and special anchors if you have false ceilings BA13 (j've put one in the laundry room with the screw kit supplied AC s ankle is broken figure, keep al mind that you will unscrew the hood to change the batteries, so if c is not securely attached, the stuff you will stay in the hand Council: change the direction of the big stack that is not indicated in the instructions, I have galley for 10 minutes to understand why it does not work
