safeSEA S200 AIS SART

The safeSEA S200 is an advanced Search and Rescue Transponder (SART). It operates on the VHF frequencies of the AIS system (161.975 and 162.025 MHz) and includes a GNSS (GPS) receiver. In case of distress, it transmits your exact position directly to chartplotters and AIS systems on nearby vessels to speed up rescue operations.

Unlike traditional radar SARTs (such as the S100 model) that respond to X-band radar signals, the S200 continuously transmits positioning data via the AIS network. This allows your position to be displayed much more accurately on the navigation screens of nearby boats.

The lithium iron disulfide (LiFeS2) battery module ensures continuous operational autonomy of over 96 hours, even in extreme cold conditions down to -20°C.

The S200 battery (reference LB3S) has a storage lifespan of five years before any significant capacity loss. An expiration date is clearly marked at the base of the device to indicate when replacement is needed.

Yes, the safeSEA S200 is designed for the harshest marine environments and is certified waterproof to a depth of 10 meters.

The S200 integrates NFC connectivity. By bringing a compatible smartphone close, you can use the dedicated mobile app to check the battery status, review the self-test log, and confirm GNSS acquisition, all without consuming the beacon's main power.

Activation is designed to be simple, even with gloves on:

Remove the device from its mount.Break the transparent protective cover.Push the red switch down while holding the green switch to the left.Release the green switch to lock the device in the active position.

Upon activation, the green LED emits a single flash. It will then flash once every 5 seconds to indicate the device is active. A triple green flash signals that the GNSS position has been successfully acquired.

Absolutely. The S200 meets the stringent requirements of SOLAS standards, the European Marine Equipment Directive (MED/4.55 - Wheelmark), as well as UK (UK MER) and Canadian (ISED) regulations.

Yes, the battery module (part number 711S-00609 / LB3S) is user-replaceable. A hex key is included with the device to simplify this maintenance task.

The S200 is a very compact cylinder measuring 227 mm in height with a maximum diameter of 82 mm. It is very light, weighing only 315 grams with its battery (227 g without the battery).

The device comes with a wall-mount bracket for the boat. In a liferaft, it can be secured in an upright position to the canopy using its tether attachment point, or mounted on an optional telescoping pole (reference 711S-01802) to maximize signal range.

No, the SART is not a primary distress alert device. It is used for proximity location by nearby vessels. Your boat should ideally be equipped with an EPIRB beacon or an ASN radio to alert land-based search and rescue authorities.

During a test, the LED indicates the status:

3 green flashes: GNSS position acquired and test passed.3 orange flashes: Test passed but the battery will need to be replaced soon.3 red flashes: Test failed.

Currently, Ocean Signal's dedicated app for querying the beacon via NFC is available for download on Android devices only.

The transponder is designed to operate reliably in extreme temperatures ranging from -20°C to +55°C. It can be stored undamaged between -30°C and +70°C.

The device provides a transmission power of 1 Watt (EIRP), ensuring excellent VHF AIS signal transmission range to nearby vessel receivers.

It uses a 3.0V nominal Lithium Iron Disulfide (LiFeS2) battery module. Note: this advanced chemistry is not designed to be recharged; never attempt to recharge the battery.

The package includes: the S200 AIS SART transponder, the LB3S battery module, a wall-mount bracket with 4 screws, an Allen key for battery installation, and a quick start guide.

To disable the SART, reverse the activation procedure: push the green switch to the right while releasing the red switch so it returns to its initial position.
