Exposure OLAS GUARDIAN MOB System for engine shutdown

OLAS GUARDIAN Exposure Lights

The GUARDIAN is integrated into the Exposure OLAS system to automatically shut down the engine in case of man overboard (MOB).


The GUARDIAN is a device that is integrated into the MOB OLAS system of Exposure for the detection in case of a man or a pet falling overboard.

The GUARDIAN, designed specifically for motorboats, works with OLAS TAG(the small bracelet) and OLAS Float-On receivers. If a person or animal wearing these receivers falls overboard, the GUARDIAN detects it and deactivates the engine.

GUARDIAN is useful to stay in the place where the accident occurred, save valuable time and concentrate immediately on detecting the unfortunate person on sight. If it is the captain who falls overboard and the rest of the crew is on deck, then the GUARDIAN could also make a difference to the survival of the man at sea and the safety of the crew.

The GUARDIAN can connect up to 15 receivers and the installation requires only a 21 mm hole in the console to house an elegant switch, equipped with a siren and LEDs, to better warn of the eventuality.
