  • Information

Exposure OLAS Core Portable Wireless Overboard Alarm

The Exposure OLAS Core is a compact, portable overboard alarm and emergency light system. It reacts within 2 seconds of a person falling overboard and can easily be switched between vessels without the time and cost of wired instillation. The Exposure OLAS Core can connect with up to 15 Exposure OLAS transmitters and cover a vessel up to 50ft.

What it does

The Exposure OLAS Core wirelessly tracks Exposure OLAS transmitters around the vessel. When a person wearing a transmitter falls overboard the in-built alarm is triggered and a high-power emergency red light gives visual indication and illuminates the surrounding area, all within 4 seconds.

As well as triggering the Alarm, the Exposure OLAS Core connects with the free Exposure OLAS mobile application providing an easy to read arrow back to the alert position plus essential MOB last known position information and an auto populated VHF prompt screens to support the crew during the stress of a recovery operation.

Why use the Exposure OLAS Core

The Exposure OLAS Core gives skippers complete confidence that in the event of a MOB incident, the entire crew are alerted instantly and can take immediate recovery actions.

Losing a crew member overboard is every sailors’ worst nightmare. The larger the boat, the more difficult it can be to know immediately that a MOB incident has occurred, especially in the dark with crew members forward of the mast.

It can happen all too easily even in benign conditions. Wearing a physical tether, whilst advisable, is not always practical, and indeed falling overboard on a tether has been proven to be no guarantee of survival if the boat is at full speed and the skipper is not immediately aware of the incident.

Who is it for

The Exposure OLAS Core connects to 15 crew members via wearable Exposure OLAS Tag transmitters, creating a virtual lifeline. Larger vessels can be fitted with an Exposure OLAS Extender which increases the range from 50ft to 80ft. Suitable for anyone heading out on the water looking for added security and peace of mind. The Exposure OLAS Tags are compact, light eight and have user replaceable batteries, suitable for adults, children, pets or important items which may fall overboard.

Exposure OLAS Core Integration

Any Exposure OLAS Core transmitting devices, the OLAS Tags and OLAS Float-On LED light, within range can be tracked by the Exposure OLAS Core , allowing freedom for the crew to move around the deck, with total confidence that an early warning system will alert them instantly of a MOB incident, so a swift recovery can be actioned.

Connects to 15 Exposure OLAS Transmitters (OLAS Tags or OLAS Float-On)

Connecting up to 15 Exposure OLAS transmitters allows the Exposure OLAS Core to be used on onboard larger vessels. Exposure OLAS transmitters are not only designed for crew, simply by attaching a transmitter to objects such as MOB flotation devices, the dog or a yacht tender, you can always be aware if something has gone missing.

Extender compatible

An Exposure OLAS Extender, which is also 5V USB powered with an internal rechargeable battery can be used to cover areas where the transmitter signal may be blocked. This allows complete scalability and portability to vessels up to 80ft.

Portable with low power consumption – 5V USB

The portable module is powered by 5V USB power supply enabling it to be used on different vessels without requiring hard wiring.

Inbuilt Alarm

An 85db alarm will sound to indicate an Exposure OLAS transmitter has gone out of range. The Exposure OLAS Core can be linked up with the Exposure OLAS app so that alarms can be placed in 2 locations on the vessel.

Inbuilt Emergency Light

A high-power emergency Red light will illuminate, offering clear visual indication of an alert, whilst also acting as a light to illuminate the area to aid with recovery at night.

System Feedback

The Exposure OLAS Core clearly indicates how many Exposure OLAS transmitters are connected during the setup process. Transmitters can be Added/Removed from the system either using the mobile App or through simple inbuilt switching process.

Mobile App Features

The Guardian fuction is easily operated via the Exposure OLAS App, free to download from the App Store for iOS and the Google Play Store for Android.  The Exposure OLAS app requires a device running the minimum of IOS11 or Android 5.1 to work. The Exposure OLAS App is a powerful tool for controlling the Guardians functions and for aiding in fast rescue.
