RDL TX-PSD1 – Paging Sound Detector for 25/70/100 V Lines
What is the RDL TX-PSD1?
The RDL TX-PSD1 is a paging sound detector that triggers an open-collector output when audio appears on a constant-voltage speaker line. It controls RDL modules or other equipment during pages in commercial paging systems.
How does it work?
The 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 falls below threshold, indicated by a green LED. When triggered, the SLAVE terminal is pulled to ground through an open collector to control equipment with ground-activated inputs that permit a 24 V pull-up. For switching speaker loads directly, RDL offers the TX-PCR1 with DPDT relay contacts. RDL lists TX mounting accessories such as the TX-RA5 19-inch racking system and MB-1 mounting kit for this module.
What are the key features?
- Constant-voltage input — A switch selects 25 V, 70 V or 100 V speaker line inputs.
- Transformer-isolated input — The amplified audio input is isolated by a transformer.
- Adjustable sensitivity — A trimmer and threshold LED set the trigger level from -40 dB to -15 dB.
- Adjustable release delay — The output stays active for 3 to 25 seconds after the audio stops.
- Open-collector SLAVE output — The SLAVE terminal pulls to ground at 25 mA to control other modules or equipment.
