1Introduction
This document describes technical specifications and user operation of TRR2 Wireless Repeater.
Product was developed and manufactured in the Czech Republic. All rights reserved TESLA. Offer or
delivery of products or services related to the product does not include transfer of ownership rights.
Before using the product, please read this manual carefully and understand all operating and safety
precautions. Compliance with operational and safety precaution can prevent from damage to equipment or
injuries to personnel. Operating and safety instructions in the document are marked as follows:
Attention! This formatted text indicates the operating and safety instructions.
The product may only be used in the specified manner and for its intended purpose. The product may be
provided to third persons along with this documentation only.
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. It is also supplied from non-
rechargeable replaceable lithium battery which is sufficient for approximately 1 to 2 years of operation.
Attention! For setting and controling of Repeater it is essential to have wireless Central Unit in
system, see http://www.tesla.cz/en/tera-centrala/. Central Unit is not included with package of TRR2
and it is sold and delivered extra.
Setting and configuration of TRR2 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/en/ke-stazeni/.
TRR2 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)

Figure 1 - TRR2 Wireless Repeater in TERA System for Radon Concentration Measurement
Figure 2 - TRR2 Wireless Repeater in TERA System for Regulating Radon Concentrations
Regulating system diagram description - Radon measuring probes located in building transmit their
current radon concentration values to central unit wirelessly. Central unit analyzes this information and on
the basis of measured (set) concentration level value it sends wireless command to actuator which is
hardwired with power relay. Power relay switches on a fan which decreases radon concentration within an
area. After decreasing of radon concentration, actuator receives a command to switch off the fan. This cycle
repeats depending on increasing or decreasing volume activity of radon in building.

4/5
Repeater is random for location in measured property so that longer radio range is reached in wireless
net. In case of time continuous radon concentration measurement or in case of setting in regulation system
Repeater must be placed in optimal distance from Central Unit. Distance (radio range) between TRR2 and
central unit is up to 600 m in open space. In buildings it depends on number of walls, building material, etc.
Strength of radio signals (RSSI) is monitored by Central Unit.

TRR2 has distance (radio range) up to 600 m in open space. In buildings it depends on number of walls,
building material, etc.
Battery: SAFT LS 14500 3.6V, 2.600Ah (or equivalent)
5Operating Instruction
Switching on:
Remove screws and housing and insert battery (see figure below, red arrow indicates positive pole, blue
arrow indicates negative pole). Inserted battery switches Repeater on. Reinstall housing and screw in the
screws. Reverse the procedure to switch the device off or for battery replacement.
When installing antenna, hold antenna by knurled end.
Configuration:
Setting and configuration of Repeater and whole measuring system is realized by Central Unit connected
to PC and TERAview application. Central Unit is not included with package of TRR2 and it is sold and
delivered extra; see http://www.tesla.cz/en/tera-centrala/.
TERAview application, drivers and user manual with detail configuration description is free downloaded
on website: http://www.tesla.cz/en/ke-stazeni/.
For successful retranslator configuration in measuring system it is necessary to know retranslator radio
channel number (communication wireless channel) and P2P address (identification in wireless net). Both
parameters are printed out on retranslator serial number plate. Retranslator radio channel number is
possible to change by TERAview application and it must be identical to central unit radio channel number.
P2P address is permanent and it occur in one big wireless net only once. P2P address of Central Unit can be
identical to P2P address of other elements in network.

6Basic Maintenance
Battery replacement:
Current battery charge status of Actuator can be monitored wirelessly by Central Unit (see ´Operating
instruction/Configuration´). In case of low battery capacity Central Unit displays warning message.
To replace discharged battery see paragraphs ´Operating Instructions / Switching on´. Replace it with
appropriate battery type (see ´Product Specification´). Batteries can be ordered from TESLA manufacturer
or distributor (see ´ Accessories´).
7Repairs
Any repairs and non basic maintenance must be performed exclusively by Tesla manufacturer.
