The Bosch PLN-1EOL End-of-Line Supervision Board is a crucial component for maintaining the integrity of supervised public address or voice alarm systems. This advanced PCB detects the 20 kHz pilot tone essential for system monitoring.
Bosch's PLN-1EOL board supports voice alarm or PA systems by indicating the operational status through LED lights and closing contacts when the tone is detected. When the tone fails, contacts open and the LED turns off, efficiently signaling system faults.
