A smoke alarm is a self-contained device with its own sensor and sounder, usually fitted in homes. A fire alarm system is a network of detectors, call points and sounders wired back to a control panel, normally used in commercial and multi-occupancy buildings. Panel systems can be zoned and monitored, while domestic smoke alarms are typically interlinked so that one sounding triggers the others.

Most homes need optical smoke alarms in circulation spaces and main living areas, a heat alarm in the kitchen and a carbon monoxide alarm in any room with a fuel-burning appliance. Alarms are usually interlinked so all of them sound together. Exact requirements vary between new builds, rentals and existing homes, so check the current building regulations for your location.

Many commercial premises do, although the type and grade of system depends on the size, use and occupancy of the building. A fire risk assessment normally determines what level of detection and warning is required. Smaller, low-risk premises may need less, but always check current regulations and seek advice from a fire safety professional before choosing equipment.

Often yes, provided they are from the same manufacturer's system. Many ranges offer RF base modules or RF-enabled mains alarms that bridge wired and wireless devices, which is useful for extending protection to an outbuilding or loft without chasing cable. Brands are rarely cross-compatible, so stay within one range and follow the manufacturer's pairing instructions.

Domestic alarms are generally tested weekly or at least monthly using the test button, and replaced at the end of the life stated by the manufacturer. Commercial fire alarm systems are tested routinely, often weekly from a call point, and serviced by a competent person at set intervals. Follow the manufacturer's guidance and any requirements in your fire risk assessment.

Smoke alarms are typically fitted on the ceiling of every circulation space, such as hallways and landings, and in the main living room, with a heat alarm in the kitchen. Alarms should be interlinked so they all sound together. Requirements differ between Northern Ireland, England, Scotland, Wales and the Republic of Ireland, so check current building regulations and BS 5839-6.

Mains-powered alarms with a backup battery are usually required in new homes and major refurbishments, and they are normally interlinked by cable or radio. Sealed 10-year lithium battery alarms suit existing homes and rental properties where running new cables is difficult. Radio-interlinked alarms combine easy installation with whole-house warning. Check what regulations require for your property.

A carbon monoxide alarm is usually fitted in any room with a fuel-burning appliance, such as a boiler, stove or open fire, typically between one and three metres from the appliance. Many regulations now require CO alarms when new appliances are installed. Follow the alarm manufacturer's positioning instructions and check current building regulations for your area.

Most smoke and heat alarms should be replaced around ten years after installation, as sensors become less reliable over time. Many alarms show a manufacture or replace-by date on the side. Test alarms regularly using the test button and replace any that fail or are past their date. Sealed-battery models are replaced as a complete unit.
