TTD Astra-Y

TTD – Transmitting Terminal Device - is intended for:

 – controlling two own alarm loops and processing system events by built-in      indicators, 3 outputs (Relay 1, Relay 2, OC) and transmitting signals to RTD via radio;
 – receiving signals from CP connected through LIN interface and transferring them to receiver (RTD) via radio.
 – retransmitting of the signals.
