6. Approvals
6.1 ETSI
The standards used in the evaluation of this product establish the threshold values for use in residential
areas, business and commercial areas as well as in small businesses whereby the use of the product is
intended for a business environment.
This includes the following, typical sites and spaces:
-
Residential buildings/living spaces such as houses, apartments and rooms, etc.;
-
Retail areas such as stores, supermarkets, etc.;
-
Business premises such as municipal offices, banks, etc..;
-
Entertainment businesses such as cinemas, public establishments, etc.;
-
Outdoor locations such as gas stations, parking lots, sports facilities, etc.;
-
Small business offices such as workshops, service centers, etc.
All areas of application are characterized by the fact that they are connected to the public low-voltage
power supply. When using in a location in a severely electromagnetically disrupted environment such as
typical industry environments, problems are likely to occur as a result of the product's inadequate
interference immunity.

6.2 Wireless Communication reliability
The communication reliability for the Elpro radio sensor system, often referred to as Quality of service
(QoS) is based on the following principles:
"The used modulation is of the "Gaussian Frequency-Shift Keying (GFSK)" type. This is a type of
frequency shift keying modulation that uses a Gaussian filter to smooth positive/negative frequency
deviations:
- FCC compatible
- Address match for detection of incoming package
- Automatic retransmission of data packages
- Automatic CRC and preamble generation
- Build in test function for the radio signal
- Use of frequency hopping in the 915MHz band
- Limited number of sensors and transmitters used
- Installation requirements
Risk assessment
for Receivers and
Transmitters The Elpro wireless system is made up of a receiver and a transmitter function in the wireless datalogger
and in each radio sensor. The receivers are divided into three classes, each having its own set of minimum
performance criteria. The classification is based upon the impact the equipment has on persons in case
of a failure.
The Elpro radio sensor system complies to a class 2 system:
A failure causes loss of function but not physical risk of a person
