AIS Alarm box webOcean Signal has announced that it started shipping its new  to customers across the world in April.

Developed to ensure that everyone on the vessel is alerted to a possible Man Overboard (MOB) or a crew in need of rescue, the AIS Alarm Box is available from Ocean Signal’s global network of distributors and dealers.

The device is the latest addition to the UK communication and safety at sea specialist’s range of compact and easy-to-use products, expanding the company’s innovative portfolio of GMDSS and safety equipment for commercial, fishing and recreational users.

James Hewitt, Sales and Marketing Manager, Ocean Signal, said: “We are delighted to confirm we are now shipping the new Ocean Signal AIS Alarm Box. We are confident that this device will be of significant benefit to our customers as it detects any AIS MOB or AIS SART signal, including our rescueME MOB1, and sounds an audible alarm to provide crucial indication in the event of an emergency.”

Ocean Signal’s waterproof AIS Alarm Box has been developed to help save lives in the event of a man overboard incident by providing visual and audible indication the moment any AIS-MOB or AIS-SART signal is received.

The Alarm Box receives NMEA0183 input from an AIS receiver and detects all received or specific AIS SART and MOB devices, including Ocean Signal’s award-winning rescueME MOB1. Ensuring the source can be immediately identified, the Alarm Box can be programmed by USB from a Windows PC to alarm on all SARTs, all MOBs or up to 30 individual SART/MOB MMSI numbers or combinations of these. As soon as an AIS transmission is detected, a tone-specific internal alarm is sounded to identify the source – AIS-SART, AIS-MOB, Active or Test Message.

Measuring 90mm x 72mm x 72mm, the Alarm Box operates within a temperature range of -15°C and +55°C and is waterproof up to a depth of one metre.

It is compatible with Ocean Signal’s rescueME MOB1 – the world’s most advanced Man Overboard locating device, incorporating both AIS and DSC technologies within the most compact product on the market at 30% smaller than similar products.
