1.0 Objective of this Document
CyberData receives customer inquiries regarding products for outdoor notification. Since every
environment is slightly different, we decided to test our products at our corporate location and
provide those results as a general guideline for product selection. The testing was subjective in that
the results were based upon a CyberData employee standing in a specific location and determining
if intelligible audio could be heard.
2.0 Test Location
CyberData’s headquarters is located in an industrial park located in Monterey, California. Outside
the building are closely-spaced oak trees with good “see-through” visibility. The cul-de-sac is
relatively quiet with the exception being Upper Ragsdale Drive. The speakers are mounted on the
top corner of the building facing 90 degrees from each other. They are mounted 18 feet off the
ground. Various locations were selected at different distances and elevations. To provide an ambient
noise assessment, each location was tested for ambient noise prior to the test messages being
broadcast. This test was accomplished with a digital sound pressure meter.
3.0 Test Configuration
The system consisted of a CyberData Paging Amp being configured in High Power (802.3at) mode
registered to a 3CX server on the premises. A Grandstream SIP phone was located in the QA lab
within the building. The Paging Amp was located on the roof of the building and two of the
reentrant speakers (CD#011068) were mounted on the roof at the corner of the building with 8 feet of
speaker hook up wire. For the tests, a CyberData employee moved to an area (see map locations in
Figure 2) and measured the ambient noise level with a sound level pressure meter. The engineer in
the lab then slowly counted to ten. The requirement for intelligibility was that the standard
CyberData employee was able to clearly hear the ten count.
4.0 Summary
This test was subjective but will give a potential customer an idea of the outdoor notification
capability of the CyberData configuration.

heard. At each location, a decibel meter was used to show ambient noise before the test.
