Yes they do. These are 406 MHz Emergency Distress Signal devices: "Distress alerts transmitted from ELTs, EPIRBs, SSAS, and PLBs are received and processed by the International Cospas-Sarsat Programme, the international satellite system for search and rescue (SAR). These beacons transmit a 406 MHz distress signal every 50 seconds, varying over a span of 2.5 seconds to avoid multiple beacons always transmitting at the same time."
