What is the planning process?

After a customer inquiry, we work immediately to provide you with an offer tailored to your geographical location. If necessary, an on-site visit may be required.


SESCO Sound Level Planning

First of all, an exact sound level planning of the siren type is made under given, topographical conditions. For this purpose we use our in-house SESCO SOUND LEVEL PLANNING

This provides you with a quick and uncomplicated overview of which siren type and which location is best suited to your requirements. You can get an overview of our siren types here:

Overview electronic sirens »

Here is an example of how such a planning could look like:


Circular radiation 180°- Setup SES-600-2L with alignment angle 1°:

Circular radiation 360°- Setup SES-600-360 with alignment angle 323°:

Circular radiation 0°- Setup SES-600-0-4L (4 Line) with alignment angle 119°:

Circular radiation 0°- Setup SES-600-0-2L with alignment angle 45°:

Sound pressure level (SPL)

A siren signal should have a sound pressure level of at least 66 dB SPL outdoors. Since levels below 66 dB SPL are often no longer perceived inside buildings, a level of at least 71 dB SPL should be aimed for.

In any case, the siren level should be at least 10 dB above the average of the existing ambient noise. 

The maximum permissible sound level exposure time per day is specified by law.
