Ocean Signal SafeSea S100 SART

Ocean Signal SafeSea S100 SART (Search and Rescue Transponder) is a dedicated 9GHz X-band radar transponder designed to assist in the rescue of liferafts and survival craft. It complies with IMO SOLAS regulations and is a mandatory safety requirement for many commercial and regulated vessels. 

Core Functionality

• Radar Visibility: Once manually activated, the S100 remains in standby until it is swept by an X-band radar from a nearby vessel or aircraft.
• Visual Alert: It responds by transmitting pulses that appear on the searching vessel's radar as a line of 12 dots (blips), providing an exact bearing and range to the survival craft.
• Proximity Indication: As the rescue vessel gets closer, the dots on the radar display transform into concentric circles. 

Technical Specifications

• Operating Life: Provides over 96 hours in standby mode followed by 12 hours of active transmission.
• Battery: Uses a user-replaceable, non-hazardous Lithium/Iron Disulfide (Li/FeS2) battery with a 5-year replacement interval.
• Durability: Waterproof up to 10 meters and operational in temperatures from -20°C to +55°C.
• Size: Compact (227mm height x 65mm diameter) for easy packing into liferaft containers. 

Deployment and Use

• Mounting: Should be mounted at least 1 meter (3.3 ft) above sea level for maximum effectiveness. It comes with a quick-release storage bracket and a telescopic pole.
• Activation: Requires a simple manual two-step process: breaking a protective cover and sliding/holding a switch.
• Testing: Features a built-in test mode to verify operation without triggering a full distress signal.
