2Description and Utilization
Repeater is an autonomous element designed to increase the system range. It provides connection
between the central unit and other elements of wireless net where signal is too weak for direct connection.
This may happen in an empty space at a long distance. The range in buildings is dependent particularly on
building material (walls, partitions, floors, etc.). For example, in case of reinforced concrete skeleton, which
represents efficient shielding, problem can occur even at very short distances. Repeater contains radio
module which only repeats (retransmits) received data in both directions. The device can be switched
ON/OFF by switch. LEDs „STAT“ a „CHRG“ indicate current status of device see ´Operation manual´below.
Internal accumulator ensures autonomous operation due for more than 1 year after full charging. For
permanent powering is possible to connect power adaptor 230VAC/5VDC.
Attention! For setting and controling of Repeater it is essential to have wireless Central Unit in system,
see http://www.tesla.cz/. Central Unit is not included with package of TRR3 and it is sold and delivered
extra.
Setting and configuration of TRR3 Wireless Repeater and whole system is also managed by connected
computer to Central Unit and TERAview application on PC.
TERAview application, drivers and user manual with detail configuration description is free downloaded
on website: http://www.tesla.cz/.
TRR3 Wireless Repeater can be used in these systems:
A) TERA System for Radon Concentration Measurement (Figure 1)
B) TERA System for Regulating Radon Concentrations (Figure 2)
