The first task that MSI carried out, was to examine and understand the various causes of the unwanted alarm activations. We found that unwanted alarm activation causes generally fall into two groups:
1) Operator / client related causes
The largest number of operator related causes occur at alarm setting and unsetting times. The majority of these causes can be resolved by operator understanding which can be improved by training and education. MSI reviews all its clients alarm activations on a daily basis to ascertain the cause of each. If ever the cause is found to be as a result of operator error, we will initiate additional training or instruction for system operators.
2) Alarm installing company related causes
These causes are more diverse, but predominantly involve the System design specification, the design of the detection equipment, the processing of the information that the detectors generate to the control equipment and the evaluation of this information by the control equipment before the alarm activates and before it makes a request for attention by setting off sounders, calling keyholders and alarm receiving centres etc.
The traditional analogue detectors in common use, will react to anything outside their preset tolerance band, by immediately signalling an alarm condition to the control equipment which, upon receipt of this signal, will immediately generate an alarm condition requesting attention by setting off sounders , calling keyholders and alarm receiving centres etc., leaving the alarm receiving centres to filter the effect (i.e. interpret the validity of the information that they receive), before calling the Police or other Response Organisation to attend to the premises. 
So what is it that affects the traditional analogue detection equipment, that makes them produce unwanted alarm activations and how can these affects be nullified?
Quite simply, External Causes, such as electrical or electromagnetic interference and over sensitivity caused by environmental conditions.
