Applications, building by building
The same physics applies everywhere, but the design brief changes completely: a family home is protected by four self-contained alarms, a hotel corridor by an addressable loop, a cold store by heat detection rated to −25 °C.
Residential
Houses, flats, rented property, HMOs, sheltered housing and care homes — where the occupants are asleep, untrained, or both.
Residential protectionCommercial
Hotels, offices, retail, schools, hospitals and restaurants: escape routes, strangers, alarm zoning and cause-and-effect.
Commercial applicationsIndustrial & logistics
Warehouses, factories, cold stores and data halls — large volumes, dust, extreme temperatures and high consequence of downtime.
Industrial applicationsSpecial environments
Kitchens, bathrooms, laundries, garages, lofts and dusty workshops: the rooms where ordinary smoke detection fails.
Difficult roomsSmart & connected
Wireless interlink, app notification, remote monitoring and the specific value — and limits — of connected devices.
Connected systemsCompliance by market
Which standard applies where, and what the legislation now requires in dwellings across Europe, North America and Australia.
Standards & lawThe design questions that change by building type
| Question | Small dwelling | Managed building | Industrial site |
|---|---|---|---|
| Who is protected? | The occupants, who know the building | Strangers, guests, staff, the public | Staff and contractors, often alone or in small teams |
| Who responds? | The occupants themselves | Trained staff, then the fire service | An alarm receiving centre and an on-site team |
| Detection type | Self-contained alarms, Grade D or F | Panel-based system, addressable preferred | Panel-based, often with beam or aspirating detection |
| Fastest acceptable response | Seconds — waking sleeping people | Seconds to tens of seconds, with clear zoning | Early warning to protect assets and processes |
| Maintenance owner | The householder | A contractor under a service agreement | A contractor with a documented permit and audit trail |
| Commonest failure | Battery removed, unit expired | Detector disabled during works, panel left in test | Sensor contaminated by process dust, detection out of service during shutdowns |
A note on what all of them share
- Detection must be where the occupants sleep, not only where the fire is expected to start.
- The alarm must be audible where people are — 85 dB at three metres is a manufacturer's promise, not a design outcome. Distance, doors and background noise all reduce it.
- Every device needs an owner and a date: who tests it, when, and when it gets replaced.
- The simplest design that meets the standard is usually the most reliable. Complexity has to earn its place in a fire system, because every extra element is another thing that can be left in test mode.
