Repeater TRR 3

Repeater TRR 3 for TERA Regulating System

The 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 the signal is too weak for direct connection. This may happen in a free space at a too long distance. The range in buildings depends particularly on the building material (walls, partitions, floors, etc.). For example, in the case of a reinforced concrete skeleton, which represents efficient shielding, a problem can occur even at very short distances.

The repeater contains a 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. 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.
