Fire Alarms

Fire Alarm Systems

Securitel believe that protecting your business premises and your employees from the risk of fire is of paramount importance. Not only that, but it’s the law as well! Ensuring your premises is fitted with a suitable fire alarm system and adequate fire detection is one step towards mitigating the risk of fire.

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:

  1. Conventional Fire Alarm
  2. Addressable Fire Alarm
  3. 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 needs to meet for your site.

Fire Alarm Categories

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 protection for earliest possible warning
  • P2 – Fire detectors for defined parts of a building

Fire Detection

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, metholated 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 detector

Designed for use in buildings with high ceilings such as warehouses and atria, the beam 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.

Video fire detection

CCTV cameras relay images to a main computer where they’re analysed. Certain patterns are actively monitored to detect either visual smoke or infra-red radiation from heat.

It’s essential that your fire alarm system is installed and commissioned by a company who is accredited by a third-party body such as BAFE. British Approvals of Fire Equipment (or BAFE) will inspect a registered company every six months’ to ensure they are installing and maintaining fire alarms to a recognised standard. They also check several other requirements such as insurance cover, quality control and the company’s and engineers’ performance to specified codes of practice.

By ensuring your fire alarm system is installed by an accredited company, you’re safeguarding yourself against fire safety legislation breaches.

Choosing a BAFE accredited company also ensures you are covered legally should anything go wrong with your system, as you can demonstrate that you considered competence when having the system installed.

Securitel is a BAFE accredited company. Therefore, you have the peace of mind that not only do we meet or exceed the highest possible business performance standards, but we also security screen all relevant staff for your safety. We take pride in ensuring your fire alarm installation not only meets the required fire safety standards, but also meets the requirements of your individual business. You, your business premises and the safety of your employees is our main priority.


Once your fire alarm is installed, your Securitel engineer will commission the system. You will be issued with an official notice that your system complies with fire safety legislation, such as a BAFE Certificate of Conformity.

Once your fire alarm system is commissioned, your engineer will demonstrate how to use the system and the fire alarm panel and will also show you (or your nominated competent person) how to perform the weekly test.
