Fire Alarm

Fire Alarm System Category
- M - Manual Fire Alarm System
- L1 - All Areas
- L2 - Defined Areas in Addition to L3
- L3 - Escape Routes & Rooms Onto Escape Routes
- L4 - Escape Routes
- L5 - Defined Specific Areas
- P1 - Full Building Protection
- P2 - High Risk Area Building Protection
Manual Fire Alarm System
These are the least sophisticated of systems, which rely on the building’s occupants to detect a fire and provide a warning to others. When a fire is discovered, employees must activate the alarm manually, in order to alert everybody else in the building to the danger.

A typical example of a manual fire alarm system is a series of break glass units, which are installed at each point of exit in a building. This allows those escaping a fire to raise the alarm as they leave the danger zone.

Manual fire alarm systems can be effective but due to reliance on individuals, it means that there can be an increased risk of employee and visitor safety, especially if the site is not highly populated with few people to raise an alarm.
L1 All Areas
This is the most comprehensive fire alarm system, which features detectors in all areas of a building where a fire could feasibly start. Detectors are linked up to a centralised alarm system which alerts the whole building should a fire break out.

The objective of this setup is to ensure that inhabitants are given the earliest possible warning, should an emergency occur.
L2 - Defined Areas in addition to L3
Fire alarm systems that fall into this category feature automatic detectors in all rooms that form part of an escape route, including corridors. Detectors also need to be installed in all high-risk rooms, such as kitchens, boiler rooms and areas with heavy plant machinery.

L2 systems are effective at providing an early warning to occupants beyond the source of the fire and those working in high risk areas. Examples of properties that typically employ this system include factories or medium sized residential premises.
L3 - Escape Routes & Rooms Onto Escape Routes
Standard life protection systems feature detectors in all escape routes and rooms that open onto an escape route. The objective of this system is to ensure that all inhabitants of the building are given enough warning to escape a fire, before their exit is impeded by the presence of flames, smoke or toxic fumes.

This category of fire alarm system is typically adopted in regular sized office blocks and commercial buildings that have flights of stairs.
It would be the ideal standard for Hotel type accommodation as a minimum
L4 - Escape Routes
An L4 category fire alarm system consists of detectors within escape route areas only, such as in corridors and stairways. Any circulation areas that make up part of the escape passage should also be fitted with a detector when the site is classed within this fire alarm category.

Commercial properties that generally adopt this category of system are those that have a lower level of risk.
L5 - Defined Specific Areas
L5 fire alarm category systems are those that are installed to tackle a specific fire risk in a certain area of a building. For example, if there is a room in a building that poses an exceptional hazard because of the items stored there or business activities carried out there.

An L4 category system may be appropriate for the building in general but an L5 system will recognise the level of risk presented.
P1 - Full Building Protection
A P1 fire alarm system involves installing detectors in all areas of the building. The objective of a system like this is to protect buildings that are critical to the operations of a business.

By implementing maximum protection across a whole site, those in charge of fire safety can ensure that any fire that breaks out is detected and neutralised as quickly as possible. This lowers the risk of damage and disruption and in turn, the financial impact that a fire could inflict on a company.
P2 - High Risk Area Building Protection
In a category P2 fire alarm system, fire detectors are installed in high risk areas only. Whilst a system like this does not provide the same level of cover as a P1 solution, it does provide early detection for the most likely sources of a fire.

This early detection will decrease the time it takes for the fire services to arrive on the scene and will help to minimise any damage to the property and losses to the business

The description of a units’ function shall give a clearly understood definition. Permanent typed labels
(Dyno tape or similar approved) shall used to identify distribution boards and isolators.

The installation shall be divided into separately controlled circuits, as required to maintain
phase balance and phase distribution within the building, further sub dividing where necessary to ensure
compliance with British Standards including earthing and equipotential bonding. Dedicated ‘clean earth’
systems shall be provided to all communications/AV equipment.

Equipotential Bonding is not a requirement where an extraneous potential difference is not possible. MAB has a mix of metallic and non metallic pipework entering the building. The highest risk being where staff are likely to work off metal benching or shelves. Noted this will apply to legacy buildings where less modern distribution equipment and circuit protection exists. Where entering services are polyethelene and bonding may be unnecessary.

New distribution boards shall be manufactured from sheet steel and be fitted with miniature circuit breakers (mcbs) or residual current devices (RCD/RCBO). Each distribution board shall be fitted with a hinged lockable door and an integral isolator. Metered distribution boards or separate meters should be used to comply with Part L of the Building Regulations using TM39 as a guide.
