The BMS will slow the spread of fire as the entire air handling
system has been shut down. That’s good news for preventing
the spread of fire, but bad news for business, particularly if the
computer room that houses all the customer records is now
starting to overheat because the feed for the air conditioning has
been cut off.
Once the all-clear has been given to go back into the building, the
employees may find that they have no work to go back to. The
servers have shut down (if they are lucky) or they have overheated
and critical business information is inaccessible whilst the IT
manager implements the disaster recovery procedure to bring
online yesterday’s back-ups. This is not a good situation for today’s
customers - all for the sake of intelligent control.
1.2. The smart option
Here the same scenario
is assessed, but using the
intelligent approach. The
fire alarm has operated,
and this time it is possible
to tell if it is a false alarm.
In the event of a fire alarm
activation, the same
CCTV cameras used
to protect people and
property against theft and
vandalism can now be automatically coordinated to check for the
presence of a fire. Now the Brigade only needs to attend when
the operator sees the tell-tale signs on their monitor – a confirmed
response. In addition, the CCTV recording system will archive the
images taken from the cameras closest to the fire in the minutes
before the alarm, providing important information on the cause of
the blaze (or the false alarm).
The access control system responds to the alarm, allowing quick
and easy egress from the building, whilst also preventing access
by those without appropriate access rights to important areas
unaffected by the fire. As the fire spreads, the access control
system adjusts in accordance with the needs of the occupants and
the applications within the building.
In addition to the security benefits that truly intelligent integration
brings, the access control system also provides a muster report of
personnel locations, based on where they were last logged inside
or outside the building. This provides an accurate picture for the
emergency services to work with in a rescue scenario and increases
the chances of a successful resolution whilst also reducing the risk
posed to rescue staff.
The BMS will control air handling units, switching them on or off
in conjunction with the spread of fire and intelligently selecting
the areas of the building to isolate whilst other systems continue
to function normally. This avoids unnecessary loss of business
without sacrificing speed of response. It’s not just the fire system
that senses the effects of heat. The BMS could be used to report
temperature changes in the areas identified by the fire alarm,
helping to support, albeit with secondary information, confirmation
of a genuine fire condition. This illustrates how a little more
intelligence goes a very long way.

1.3. how Is Intelligent Integration Achieved?
Systems can be integrated by using a hardware or software
solution. The hardware solution is often very limited in the amount
of control and information that can be shared between systems,
especially those that are already established in a building.
It is similar to getting something to work on a PC. Hardware
solutions are designed to meet certain defacto standards and if
the building user’s system is in some way different, it won’t do all
that is required. A significant amount of time might be spent liaising
with different manufacturers when something does not work.
Meanwhile, the building is not fully provided for.
The software solution on the other hand is very flexible, particularly
if used with the manufacturer’s entire building solution. This
approach can grow with the building, making use of new software
releases and will readily share information between systems for
display and control from one common platform.
Systems can be added as and when required and the software
solution is not reliant upon components being in place from the
beginning. Specific modules can be introduced and engineered
to take care of their respective application. A life safety module,
for example, will provide the interface between the fire system and
the integration package, providing visual representation of cause
and effect.
In this way, an entire enterprise or building can be fully integrated
over a period of time, reducing the impact of cost whilst maximising
the effect on reducing risk. If all of the system components come
from one manufacturer, the likelihood of a compatibility issue is
reduced to zero, as the manufacturer takes total responsibility for
the entire system.
With the emphasis across Europe on risk management and control,
an intelligent approach can really help a user to manage their risks
and to comply with local requirements.
3. Conclusion
In answer to the question, is integration a buzz word, it’s certainly
a much mis-used term within the industry. However, a smart, truly
intelligent approach to integration offers so much more. It not only
makes sense with regard to safety and security, but can safeguard
