Exposure OLAS Guardian Wireless Engine Kill Switch


The OLAS Guardian is a wireless engine kill switch that acts within two seconds of a person falling overboard. It has the dual function of also acting as an instant, Man Overboard Alarm system. The Guardian simply connects with up to 25 OLAS transmitters and can cover a vessel up to 50ft.

Exposure OLAS Guardian Wireless Engine Kill Switch


OLAS Guardian means power boat and RIB drivers are assured that their boat will stop in an instant, should the skipper or crew get separated from the boat, reducing the chances of a serious accident from a loose, unmanned, uncontrolled powerboat. They are free to move around their boat without constantly having to remember to attach, detach and re-attach a physical wired kill cord.

OLAS Guardian is for drivers of power and motor boats, and all skippers and boat owners concerned about onboard safety. It wirelessly connects up to 15 crew members via wearable OLAS transmitters (wrist Tags or OLAS Float On Light) creating a virtual kill cord.

Key Features & Advantages

  • Run alongside existing Kill switch - The Guardian can be used in-place of or alongside an existing kill cord switch and will operate if the physical kill cord has not been attached to the driver. On most engines, a simple parallel connection to the existing kill switch will enable full wireless cut-off capability.
  • Automatic restart - After 5 seconds the kill switch is deactivated enabling the engine to be restarted
  • Inbuilt Alarm - An 85db alarm will sound to indicate an OLAS transmitter has gone out of range.
  • Inbuilt Emergency Light (if externally mounted) - A high-power emergency Red light will illuminate, offering clear visual indication of an alert whilst also acting as a light to illuminate the surrounding area.
  • Relay selection - The OLAS App allows individual relay selection for easily adjusting if the OLAS transmitter triggers the engine cut-off/relay, or only triggers the Guardian's inbuilt MOB alarm.
  • Automatic connection - When you board your vessel and switch on the power, The Guardian will automatically connect to any active OLAS transmitting device within a 2m range.
  • No connection alert and override - If you board the vessel and no transmitters are switched on, the Guardian will sound an alert. This alert can be stopped either by connecting the OLAS transmitter to the Guardian or the Guardian can be manually switched off. After which the vessel can be driven as usual using the existing physical, safety kill cord.
  • Pause mode - The system can be placed into pause mode. This is used when you need to leave the boat with the engine idling, such as walking down a pontoon, knowing the OLAS transmitter will go out of range.
  • Connects up to 25 OLAS Transmitters (OLAS Tags or OLAS Float-On) - Up to 25 transmitters allow larger vessels to connect crew and objects to the Guardian. Simply by attaching a transmitter to object such as a MOB flotation device or yacht tender you can always be aware if something has gone missing.
  • Extender compatible An OLAS Extender can be used to cover areas where transmitter signal may be blocked. This allows use on larger vessels up to 80ft and the ability to scale the system up if required.
