Installed on the bridge or command station, the Mobilarm Crewguard continuously monitors the 121.5 MHz frequency for emergency signals from a Sea Marshall alerting unit.

On detecting the signal, the Mobilarm Crewguard automatically sounds the alarm and displays a man overboard warning light. Proximity to the man overboard is indicated via a simple LED display. Additional Direction Finding equipment may be necessary to locate man overboard.

The Mobilarm Crewguard can interface with onboard systems to automatically activate or deactivate devices, such as engine shut-off, auto-pilot, external sirens and strobe lights.

In a lone-worker environment, the Mobilarm Crewguard can be connected to an auto-dialer that will call up to 8 land lines or cell phones to call for help.
