RDL notes it is ideal for muting local speakers during an area page in commercial paging systems.\u003c\/p\u003e\n\u003ch2\u003eHow does it work?\u003c\/h2\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/rdlnet.com\/wp-content\/uploads\/2024\/01\/tx-pcr1.jpg\" alt=\"RDL TX-PCR1 Paging Controlled Relay for 25\/70\/100 V Lines\" style=\"max-width:100%;height:auto\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003cp\u003eThe amplified source connects through a transformer-isolated detachable terminal block, with a front-panel switch selecting 25 V, 70 V or 100 V; the 25 V setting also accepts 8 Ω sources up to 75 W. A sensitivity trimmer and red threshold LED set the trigger level, and a delay trimmer holds the module triggered for 3 to 25 seconds after audio stops, shown by a green LED. When triggered, 8 A DPDT relay contacts can connect local speakers to the paging line and return them to the local amplifier after the page. An open-collector SLAVE terminal can control additional TX-PCR1 modules or other equipment.
