Jotron Tron 45S EPIRB - Bulkhead Bracket
Tron 45S Manual EPIRB
Bulkhead Bracket Version
When activated, the Jotron Tron 45S/SX begins transmitting vessel identity to the geostationary and polar orbiting satellites equipped with COSPAS/SARSAT transponders.
These satellites receive the information and forward it to a Ground Receiving Station (LUT), where the position will be calculated and transferred to a Mission Control Centre (MCC).
At this point, necessary demands will be sent to the correct Rescue Control Centre (RCC), where rescue operation details will be co-ordinated and Search & Rescue Forces (SAR) will be dispatched to provide assistance.
Features
- Operates on the SARSAT/ COSPAS frequency 406 MHz.
- Identification and positioning via satellite.
- Transmits also on the air traffic emergency frequency 121,5 MHz for homing.
- Designed for small vessels and various other applications.
- Manual or seawater activation.
- Manual switch panel and strobe light.
- Light weight and small size.
- Standard 24 hours operational time.
