ACR OLAS Extender (for Core & Guardian)


Whilst the main devices of ACR OLAS work perfectly well for smaller boats up to 50ft, one of the limitations of the OLAS Guardian and OLAS Core is their range. If you have a larger vessel up to 80ft then you have the option of adding the OLAS Extender to your existing setup, giving you a much wider transmission range.


The device is compatible with the two main base alert systems, as well as the Float-On transmission device and the OLAS Tag, providing you with the peace of mind that you will get the highest transmission levels possible in case of emergency.


Why is the range of transmission important?

Due to the way the whole OLAS system works, Overboard Location Alert System, the Bluetooth connection can measure how far you are away from the main control system that is monitoring you via the watch-like Tag on your wrist.


If you are on a boat that is just 25ft long, then if you go overboard and your boat continues away from you a further 30ft, then an alarm will trigger as you’ve exceeded the distance of this virtual tether. However, on a longer boat of maybe 60ft or 80ft if the main base control device is situated at one end of the boat, then if you walk 50ft to the back of the boat, the device is going to think you’ve exceeded the distance and have gone overboard, triggering the alarm unnecessarily.


What the OLAS Extender does is increase the distance you can be away from the boat console, so you and your crew can walk around the whole vessel without the alarm triggering, however if you then go overboard and the vessel moves away, only then will the alarm sound.
