When the vessel is in distress, VEP8 shows bit standard will be automatically ejected from the release device, transmitter 406MHz emergency signal, Cospas / Sarsat system satellite signal is received, will be communicated to the shore-based terminal. LUT (Local User Terminal) decoding analysis to produce bit, position, and to convey the RCC (rescue center), in order to implement the emergency.
VEP8 satellite emergency position indicating radio beacon designed according to the latest national and international standards for domestic and international various vessels. Additional 121.5MHz locator transmitters to facilitate maritime search and rescue teams quickly locate the location of the incident, significantly shortening the rescue time.

Product Features:
Automatic and manual start; contain the 121.5MHz auxiliary locator transmitter to facilitate wireless relocation; automatically release the device with a hydrostatic release unit; automatically turn on at night, high-brightness flash; GPS global positioning system.
The VEP8 is available as float-free deckmounted device using HydrostaticRelease Mechanism to be activated automatically on 4m depth.
Three LEDs provide indication of 406 ( COSPAS-SARSAT) and 121.5MHz ( SARhoming Frequency ) transmitters and battery status .
Easy Changeable 2-cell Lithium battery with 5 years life . Small size and weight make PRO-5 anideal solution for pleasure boats and yachts .

Brief introduction:

Model Number:

406mhz Satellite Emergency Beacon VEP8

Application Area:

Global search and rescue in distress, which can transmit distress signal of 406MHz and pilot signal of 121.5MHz.



COSPAS, CCS,and ZY,meeting with standard of IMO/IEC



VEP8 can be activated automatically or manually when ships in distress. Then the emergency signal of 406MHz for help will be transmitted and forward to the search and rescue center by satellite. The search and rescue center will carry out the emergency rescue plan according to the received signal.



1.Low maintenance cost for battery and hydrostatic releaser.


2.Low stray, low harmonic, low power-consumption and long time for stand-by and working.


3.Double protection systems for mis-sending with more safety.


4.Easy to be found because of eight highlight LED lamps.


5.Ten types of messages with fault diagnosis and overall check for EPIRB.
