    Hmm, open plan log home, or does it have rooms? I'd plan to have one local to a device/place such as boiler or kitchen, as well as one on say the landing, rather than rely on a specific square footage. Time to detect and raise an alert , giving you time to respond/evacuate, would be a better method to determine how many you need, in my opinion.

  • If you could afford it you could have one in every room (apart from your kitchen) to detect smoke at the earliest stage of a fire as possible. Kitchens would need a heat detector due to the presence of cooking fumes. Smoke alarms are usually very good at picking up smoke even if you can't see any and from over a greater distance than you'd think. Usually any smoke produced downstairs will likely activate the upstairs alarm even if the downstairs one doesn't due to the way smoke rises. The minimum coverage for a typical house is usually top and bottom of your stairs to make sure your means of escape is not compromised by alerting you before there is an excessive build up of toxic smoke. It also means there is an alarm near to the rooms you spend most time in - your bedrooms and living room. Consideration must be made not to position near to steamy shower / bathrooms, directly above heaters, next to light fittings and also not tucked away in corners or tight up against the wall. If it is in a corner the smoke being carried in the air flow might swirl around in these areas and initially miss the alarm. Also if the alarm is on a wall then it is possible that smoke would need to fill the ceiling area first before creating a low enough plane to reach the alarm due to smoke rising and travelling to be highest areas first.
    Keeping doors closed at night will also give you additional time if a fire was to happen. Smoke would still get through the gaps in the doors to activate alarms but the closed compartments you create will contain the spread of fire better, reduce smoke damage to the rest of the property, reduce the amount of oxygen the fire has to use in that compartment and mainly buy you time to evacuate everyone safely and calmly and call the Fire Service. Your kitchen door will be the most important to keep closed due to the amount of appliances in there. Try to avoid leaving things switched on and running throughout the night to reduce the risk of fire from faults.
