Consultancy & System Design Services are services offered to customers who require engineering advice when designing a new system or scaling an existing Public Address/General Alarm System.
During the consultancy, our engineers help the customer to improve the system performance and give advice on individually tailored configuration. We further advise the customer to identify system bottlenecks and weaknesses plus suggest courses of action to improve the system’s overall responsiveness.
Finally, we are focused on the system’s reliability, allowing the customer to take proactive measures to avoid problems, now and in the future.
See more about how we ensure optimal siren coverage in our Acoustical Planning Datasheet.
As part of our comprehensive service, our engineers can be involved in any, or all, of the steps that leads to the design of a new Mass Notification System. The following Site Survey lays out the normal steps of the consultancy service.
Our System Concept Design often starts with a detailed Site Survey during which we assess the customer’s requirements for the Warning System Solution such as:
Integration to other systems such as Fire & Gas, Public Address, PABX etc.
Types of warning required
Desired System Functionality
Inspection of Site Conditions such as Hazardous Areas, Type of Dangers etc.
Background Noise Level, Noise Mapping and Acoustic Analysis

To ensure that the warning siren sound propagation will actually cover the related areas our engineers can perform field test measurements of the Background Noise Level. The noise measurements serve as the basis for a Noise Mapping and Acoustical Analysis. Creating a noise map gives a comprehensive overview that in a graphical manner helps identifying weak spots in the sound coverage from the warning siren system.
Noise mapping requires the systematic buildup of individual noise source activities and levels which are fed into a calculation engine to create a range of noise metrics. Comparing the sound output from the warning sirens to the background noise level gives a comprehensive map of sound propagation coverage.
The sound propagation coverage is compared to the sound levels and coverage areas to ensure that these correspond to the International and local standards and regulations given for the area.

The Action Matrix is a tool that helps identify the types of warning required, their initiation procedure and the area that has to be covered by the alarm. The Action Matrix procedure requires careful planning and is developed in close cooporation with the customer.
