safeSEA S200 AIS SART

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

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

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

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

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

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

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

Remove the device from its bracket.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 will flash once. It will then flash once every 5 seconds to indicate the device is powered on. A triple green flash signals that the GNSS position has been successfully acquired.

Yes. The S200 meets the stringent requirements of SOLAS regulations, 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) can be replaced by the user. A hex key is provided with the device to facilitate this maintenance operation.

The S200 is a very compact cylinder measuring 227 mm in height with a maximum diameter of 82 mm. It is very lightweight, 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 telescopic 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 successful. 3 orange flashes: Test successful but the battery will soon need replacing. 3 red flashes: Test failed.

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

The transponder is designed to operate reliably in extreme temperatures ranging from -20°C to +55°C. It can be stored without damage 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 vessels' 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 its 4 screws, a hex key for battery installation, and a quick start guide.

To deactivate 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.
