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.
TTD Astra-Y
TTD – Transmitting Terminal Device - is intended for:
