TERMINAL TRANS REPEATER
TTR-7002
This device facilitates communication by interlocking Head-End of the control room and MTR (Main Trans Repeater) devices. It receives fire, business radio signals and FM broadcast signals from the control room and MTR, modulates the frequency, amplifies them, corrects to a stable signal and transmits them to the indoor transmission line. Also It performs the function of transmitting radio signals received from indoor transmission lines to all outdoor and indoor transmission lines by frequency modulation, amplification, and correction of stable signals.
It is a two-way Terminal Trans Repeater divided into 2 bands so that communication failures do not occur even when both fire fighting and business radios are used at the same time.
The radio frequency for firefighting using a single 450MHz frequency is physically configured in both directions to implement a function that does not cause communication failures in inter-level calls.
By transmitting the frequency from the microwave (450MHz) band with high transmission loss to the microwave (20~70MHz) band with low transmission loss, the amplification process is significantly reduced and noise generation is minimized, thereby maximizing the performance of call quality.
