The ACR OLAS Guardian is a small wireless engine kill switch that acts within two seconds of a person going overboard. It has the dual function of also acting as an instant Man Overboard (MOB) Alarm system. OLAS GUARDIAN offers powerboat, motorboat, and RIB drivers the security of knowing 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 vessel. They are free to move around their boat without constantly having to remember to attach, detach, and re-attach a physically wired kill cord. The GUARDIAN provides coverage for vessels up to 50 feet and is scalable via the use of the OLAS EXTENDER for use on vessels up to 80 feet.
NOTE: As of April 1, 2021, the U.S. Coast Guard implemented a new law passed by Congress requiring the use of engine cut-off switches (ECOS) and the associated engine cut-off switch link (ECOSL) on recreational vessels. The law is relevant to all federally navigable waterways and specifically applies to recreational vessels with the following characteristics:
- Vessels less than 26 feet in length
- Vessels with an engine capable of 115 lbs. static thrust (approximately 2-3 hp)
- Vessels built in January 2020 or later
Exemptions to the Engine Shut Off System law are as follows:
- The law is not applicable to law enforcement or other government-owned vessels
- There is no requirement to wear the Engine Shut Off System link if either the main helm is installed within an enclosed cabin or if the vessel does not have an ECOS and is not required to have one
- The Engine Shut Off System link does not need to be attached/active when the vessel is operating at less than displacement speed (ie. the vessel isn’t operating on plane). This applies to common activities such as idling, docking/trailering, trolling, and operating in no-wake zones.
The GUARDIAN functions as a wireless kill cord, which when connected to your engine’s kill switch will stop the engine within two seconds of becoming disconnected. Given that the OLAS GUARDIAN also wirelessly connects up to 15 crew members via wearable OLAS transmitters (OLAS Tags or OLAS Float-On Lights), it essentially creates a virtual kill cord attached to each transmitter. Within two seconds of an OLAS transmitter losing connection, either by going overboard or via separation by distance, the engine will cut out, and a loud alarm is triggered. The engine can be restarted after five seconds, and a rescue can be performed. The rescue process is then simplified by the GUARDIAN’s ability to connect with the ACR OLAS mobile app which, in the case of a MOB incident, provides an easy to read directional screen showing the direction where the alarm was triggered and advises on the correct mayday call.
The system offers a comprehensive list of distinct advantages including:
OLAS Mobile App Operation
OLAS Guardian is easily operated via the OLAS Mobile APP, which enables you to set how long it should take for before the engine is shut off. The app also enables selecting if the external alarm when a Tag wearer is out of range should activate on both the GUARDIAN and your mobile device.
Run alongside existing engine shut off switch
The award winning OLAS 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 the full wireless cut-off capability.
After 5 seconds the kill switch is deactivated enabling the engine to be restarted
An 85db alarm will sound to indicate an OLAS transmitter has gone out of range
Inbuilt Emergency Light
A high-power emergency Red light will illuminate, offering a clear visual indication of an alert whilst also acting as a light to illuminate the surrounding area
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
When you board your vessel and switch on the power, OLAS Guardian will automatically connect to any switched on OLAS transmitting devices within 2 meters 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.
The system can be placed in a 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 15 OLAS Transmitters (OLAS Tags or OLAS Float-On)
Up to 15 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. Perfect for large crew, family, or the boaters with lots of pets
An OLAS Extender can be used to cover areas where the transmitter signal may be blocked. This allows use on larger vessels up to 80ft and the ability to scale the system up if required.
Set up and monitoring
The Guardian module can be connected to your vessel’s power supply to ensure it is always connected when you have the power running. The power wires can simply be spliced into an existing power supply from the boat’s battery.
Through panel mounting
The compact, stainless steel switch requires minimum adjustment to your existing center console, allowing it to be fitted through an 18mm hole
Color-coded control switch
The color-coded control switch makes the system easy to control and setup, without the need for the OLAS App. During the setup process, it will indicate the automatic setup stages with red indicator light. When the system is running it shows a green light, switching back to red in an alarm situation.
OLAS Mobile App data and monitoring
Monitoring tracked OLAS Transmitters enabling customized ID names for easy identification
It records the GPS location of the Alert position and guides the user back to the location and advises on the correct mayday call.
Selects which devices initiate the engine cut-off
It monitors the battery level of OLAS tags
Adds/removes tags from the sample
Activates/Deactivates the Alarm system
Operate as an external Alarm
The GUARDIAN indicates how many OLAS transmitters are connected during the setup process.
Transmitters can be Added to the system either using the mobile application or through a simple inbuilt switching process.
