Where to Put Interlinked Smoke Alarms in Scotland

First: Understand Scotland’s Legal Requirements for Interlinked Alarms

• All homes (houses, flats, maisonettes) must have interlinked smoke alarms in the correct locations.
• Alarms must be interconnected so that triggering one activates all others (wireless or hardwired systems are both acceptable).
• In addition to smoke alarms, a heat alarm is required in kitchens (where smoke from cooking often causes false alarms).
• CO alarms are mandatory in any room with a solid fuel burning appliance (e.g., wood-burning stove, open fire) or a gas boiler/heater.
• Alarms must be mains-powered with a backup battery (replaceable or sealed for life) to ensure functionality during power cuts.

Key Placement Rules for Interlinked Smoke Alarms in Scotland

1. Hallways & Landing Areas (Mandatory)

• Every floor with living accommodation must have a smoke alarm installed in the main hallway or landing, close to bedroom doors.
• Mount alarms on the ceiling (preferred) or high on a wall (at least 30cm below the ceiling, but not within 10cm of a corner).
• Ensure the alarm is visible and not blocked by furniture, curtains, or decorations—airflow is critical for detecting smoke quickly.
• For multi-level homes (e.g., two-story houses), the ground-floor alarm should be near the staircase, and the first-floor alarm near the top of the stairs to ensure smoke travels between levels triggers all alarms.

2. Bedrooms (Recommended for High-Risk Spaces)

• While not legally required for all bedrooms, install a smoke alarm in bedrooms where someone smokes, uses electrical devices (e.g., heaters, chargers) overnight, or where a bed is positioned far from the hallway alarm.
• Avoid placing alarms directly above or within 1m of a bed—this can be disruptive if an alarm activates, but ensure it’s still within range to wake occupants.
• For en-suite bedrooms, install the alarm outside the bathroom (not inside, where steam can cause false alarms) but close to the door.

3. Avoid These Placement Mistakes

• Kitchens: Never install a smoke alarm here—use a heat alarm instead (smoke from cooking will trigger frequent false alarms). Keep smoke alarms at least 3m away from kitchen doors if possible.
• Bathrooms/Shower Rooms: Steam and humidity can damage alarms or cause false triggers. Install alarms at least 1m away from bathroom doors.
• Near Obstructions: Keep alarms away from ceiling fans, air vents, or drafty areas (drafts can disperse smoke and delay detection).
• Direct Sunlight/Heat Sources: Avoid placing alarms near radiators, lamps, or windows with direct sunlight—extreme temperatures can affect performance.
• Dusty/Grubby Areas: Attics, basements, or garages with excessive dust should use heat alarms instead of smoke alarms (dust can clog sensors).

Additional Guidelines for Flats & Special Properties

• Flats/Apartments: Each flat must have its own interlinked system (alarms don’t need to connect to other flats in the building). Install the main smoke alarm in the entrance hallway, with additional alarms on each floor if the flat spans multiple levels.
• Loft Conversions: If the loft is used as living space (e.g., a bedroom or office), install a smoke alarm in the loft area, connected to the main system.
• Basements: If the basement is used for living, storage, or contains electrical equipment, install a smoke alarm (or heat alarm if dusty) and link it to the upper-floor alarms.
• Houses with Open Staircases: Ensure the ground-floor alarm is positioned to detect smoke rising through the staircase—avoid placing it too close to the stairs if drafts are an issue.

How Many Interlinked Smoke Alarms Do You Need?

• 1-bedroom flat (single floor): 1 smoke alarm (hallway) + 1 heat alarm (kitchen) + CO alarm (if applicable).
• 2-story house: 2 smoke alarms (ground-floor hallway + first-floor landing) + 1 heat alarm (kitchen) + CO alarm (if applicable).
• 3-story house: 3 smoke alarms (one per floor’s hallway/landing) + 1 heat alarm (kitchen) + CO alarm (if applicable).

Maintain Your Interlinked Alarms for Compliance & Safety

• Test alarms monthly by pressing the test button (all interlinked alarms should activate).
• Replace batteries annually (or when the low-battery alert sounds)—sealed-for-life batteries typically last 10 years.
• Replace the entire alarm unit every 10 years (most models have an expiration date).
• Keep alarms clean by vacuuming the sensors gently to remove dust and debris.
