Fire Detection System – Alarmwise UK

Current UK fire alarm regulations state that all business premises must have ‘an appropriate fire detection system’. This basically means that a fire could easily be detected and people within the building could easily be warned.

There are 3 main types of fire alarm system:

Conventional Fire Alarm
Addressable Fire Alarm
Wireless Fire Alarm

Whilst the category of fire alarm you need will be specified in your fire risk assessment, the type of fire alarm system which should be chosen is decided from what is ‘appropriate’ for your business. Your fire risk assessment will determine and state which category standard your fire alarm systems need to meet for your site.

Types of Commercial Fire Alarm Systems

Category M systems are Manual

Alarms under this category are manual fire alarm systems where the alarm needs to be activated, for example by a person activating a break glass unit. These basic systems rely on a person to discover the fire and act on.

Category L systems are for life protection

L1 – Earliest possible fire detection
L2 – Fire detection in specified areas
L3 – Protecting paths to fire escape
L4 – Protection of fire escape routes
L5 – Localised fire protection

Category P Fire Detection Systems

Whereas Category L systems are designed to protect life, Category P systems have the primary aim of protecting a property from fire.

P1 – Complete fire alarm protection for earliest possible warning
P2 – Fire detectors for defined parts of a building

Fire Detection

Our commercial fire alarm systems are made up of a wide range of fire detection devices. Below, you will find a complete list with further information about the role they play within the fire alarm system.

Optical Smoke Detector

Optical detectors are capable of detecting the visible smoke produced by materials which smoulder or burn slowly, i.e. soft furnishings, plastic foam etc.

Combined Optical and Heat Detector

With its ability to detect a wide range of fires, from smouldering to flaming types, the combined optical and heat multi-sensor detector is suitable for a range of applications.

Ionisation detectors

Ionisation detectors, although rarely used today, are suitable for clean burning fires such as petrol, methylated spirits, or paint thinners as they are more sensitive to this type of fire than optical detectors.

CO and Heat Detector

A combined CO and heat detector provides very early warning of slow smouldering fires. Ideal for sleeping risks, the CO fire detector is also well suited to many applications where heat detection is insufficient but smoke detection causes false alarms.

Smoke, Heat and CO Detector

The multi-sensor smoke, heat and CO detector is suitable for when the environmental conditions are challenging. It uses the three sensor elements together to accurately determine the presence of fire.

Heat Detector – Rate of Rise

Rate of rise detectors detect abnormally high rates of rise of temperature.

Heat Detector – Fixed Temperature

Fixed temperature detectors detect abnormally high (static) temperatures.

Beam smoke detectors

Designed for use in buildings with high ceilings such as warehouses and atria, the beam smoke detector spreads a beam from one wall to another (up to a max of 100 metres apart) in order to detect smoke at higher levels.

Flame Detector

The flame detector is ideal for protecting large open areas as it’s ideal for fast response to flaming fires typically caused by flammable liquids.

Air sampling

Air sampling detection works by actively drawing air from the protected area through sampling holes in a pipe network. Sampled air is then filtered before being analysed by detectors.
