Following the changes in the fire reform act, the
responsibly of fire alarms in businesses lies with the
premises occupier.
Security Wise (N.W) Ltd. can provide an independent risk
assessment to determine the category of Fire Alarm
required. Following the Risk Assessment, Security Wise
can install and maintain the system for you.
Below we have listed the different categories of Fire
Systems with a brief description of their objectives.
These categories are set by BS 5839: Fire Detection
and Fire Alarm Systems for Buildings.
Fire alarm systems are installed in buildings to satisfy
one or more of the following objectives: Protection of
Life, Protection of Property, Protection against
Business Interruption, Protection of the Environment.
The following table shows the different categories of
Fire Alarms Systems that Security Wise (N.W) Ltd. can install.
Category L Systems - For the Protection of
Life
|
| L1 |
Installed throughout all areas
of a building to offer the easiest possible
warning of a fire to allow for the longest
possible time for escape. |
| L2 |
Installed in defined areas of a
building. Meets the standards of L3 systems +
the additional objective of providing early
warning of fire in specified areas. |
| L3 |
Designed to give a warning of
fire at the early stage to enable all occupants
except those in the room where the fire
originated to escape before escape routes become
impassable due to fire, smoke or toxic fumes. |
| L4 |
Category 4 systems cover escape
routes and circulation areas only. Therefore,
detectors will be placed in escape routes,
although this may not be suitable depending on
the risk assessment or if the size and
complexity of a building is increased. Detectors
might be sited in other areas of the building,
but the objective is to protect the escape
route. |
| L5 |
This is the "all other
situations" category e.g. computer rooms which
may be protected with an extinguishing system
triggered by automatic detection. Category 5
systems are the "custom" category and relate
to some special requirement that cannot be
covered by any other category. |
Category P Systems - Automatic Systems for
the Protection of Property
|
| P1 |
The system is installed
throughout the building - the objective being to
call the fire brigade as early as possible to
ensure that any damage caused by fire is
minimised. Small low risk areas can be excepted,
such as toilets and cupboards less than 1m². |
| P2 |
Detection should be provided in
parts of the building where the risk of ignition
in high and/or the contents are particularly
valuable. Category 2 systems provide fire
detection in specified parts of the building
where there is either high risk or where
business disruption must be minimised. |
