Quick Answer
A Personal Locator Beacon (PLB) and Emergency Position-Indicating Radio Beacon (EPIRB) both send distress signals to emergency responders, but the activation process differs. A PLB is activated manually by the user, while an EPIRB is automatically activated in the event of a maritime emergency, such as a sinking boat. Activation signals sent by both devices use specific frequencies.
Activation Process of PLB
The activation process for a PLB is relatively straightforward. First, ensure the device is properly registered and approved by the relevant authorities. Next, turn on the device by flipping a switch or pressing a button. Then, locate the activation button, usually a red or orange button, and press it firmly for a few seconds to send the distress signal. Some PLBs require a specific sequence of button presses or a combination lock to prevent accidental activation.
Activation Process of EPIRB
An EPIRB, on the other hand, is designed to automatically activate in the event of a maritime emergency. This device is typically deployed by a boat’s crew in the event of a distress situation, such as a sinking vessel. EPIRBs usually have a built-in immersion sensor that detects when the device is submerged in water. Once activated, the device sends a distress signal to emergency responders on a specific frequency, 406 MHz, which is monitored by satellites. The activation process is typically automatic, with the device springing into action as soon as it is submerged in water. However, some EPIRBs may require manual activation in certain situations. It’s essential to understand the specific activation process for your EPIRB, as it may vary depending on the device and its manufacturer.
