ACR Exposure OLAS Core Wireless Man Overboard Alarm & Emergency Light Receiver (EXPOLASCORE)

The ACR Exposure OLAS Core gives crews a dedicated onboard man-overboard alarm without requiring a permanent connection to the engine kill switch. It monitors paired wearable OLAS transmitters and warns when one leaves wireless range or enters the water, sounding a loud alarm and illuminating a red emergency light. Powered by 5V USB, the portable Core can move between boats and work with the OLAS mobile app for recovery guidance.

Key Features & Benefits

• Monitors Up to 25 Transmitters: Tracks compatible OLAS Tags, T2 transmitters and Float-On lights around the vessel.
• Independent Onboard Alarm: An 85dB audible alert and 55 lumen red light notify crew without requiring a phone to remain the only alarm.
• Portable USB Power: Runs from a suitable 5V USB supply without engine-kill-switch wiring.
• Scalable Vessel Coverage: Coverage on vessels up to 50ft without an Extender; compatible with one or two Extenders for larger boats.
• App-Assisted Recovery: When paired with the OLAS app, a mobile device can record the alert location and assist with return navigation.
