From February 2022 updated Fire regulations require interlinked fire detection
systems to be fitted in all Scottish Homes.

By February 2022 all homes in Scotland should have:

• Smoke alarms in every circulation space on each story, such as hallways
  and landings.
• Smoke alarms in the room most frequently used for general daytime
  living purposes.
• Heat alarms in every kitchen.
• All smoke and heat alarms should be interlinked.
• Carbon monoxide alarms to be fitted where there is a fuel burning
  appliance.
• Alarm controller *  Although the alarm controller is not a
  requirement. We highly recommend this item as it allows you to control, test and silence all the alarms in a system from one place e.g. an accessible location.
