Assignment task

Synopsis:

Below is a section taken from a Problem Domain Description for a Fire and Security Alarm Monitoring

System $($FASAM$).$ A large building requires an automated alarm system, which monitors and controls all

fire and security alarms in the building. Normally the building is divided into zones and several alarms are

associated with each zone. Alarms alert a central manned control area that may pass these on to the

emergency services or may respond personally.

Factors, which have to be taken into account in building such a system, are:

If the control area is unmanned and an alarm is activated this alarm should not be ignored if it is

potentially serious. Emergency services should be called automatically.

Some but not all parts of the building may be equipped with sprinkler systems or systems to

shut down electrical equipment. These should be activated if a fire alarm is confirmed. They

should not be activated if there are people in the same room.

The building may be equipped with direction indicators, which illuminate the route to the nearest

exit. These should be activated when a fire alarm is confirmed. At the same time, an audible

signal should sound alerting occupiers to leave the building.

A security alarm may cause some internal doors to be locked automatically. It should be

possible to isolate complete zones by automatic door locking.

False alarms are common, and it might be normal practice to have an alarm confirmed before

alerting emergency services. There are different ways of confirming an alarm. In the case of a

fire alarm, multiple sensors detecting a problem may confirm it$.$ Can you do this task: Mitigation of the FASAM Risks

In this section, construct a single risk countermeasures matrix including relevant countermeasures that you identify as being relevant to the mitigation of the identified medium and high risks in the FASAM scenario. Your matrix should also demonstrate calculations of the $$combined effect of countermeasures$$ and $$combined risk reduction$$ aggregations. Numbers throughout the matrix can be synthetically simulated or assumed.

The technical outcome of this section is a single matrix.
