In the event a crew member wearing a 1224 Salcom MOB Locator Beacon falls or is washed overboard from a commercial or recreational vessel, the beacon will activate automatically (if armed) when immersed in water.  It may also be manually activated.

Once activated, the locator beacon will transmit an emergency signal and if monitored by a locator receiver, the crew will be alerted immediately and can track and locate the missing person(s).

The emergency transmission can also be received by search aircraft, but it must be stressed that the beacon is designed for man overboard monitoring and should not be used as a substitute for an EPIRB.  

The MOB locator beacon transmits two types of identification, the unit’s serial number and a personal ID.

If monitored by a Salcom 12-25 Man Overboard Alarm and Locator Receiver, the serial number and personal ID will appear on the display.  The serial number is also transmitted in morse code making it possible to identify the unit using other receivers.

The MOB locator is about the size of a cigarette packet with its aerial incorporated in the lanyard allowing the unit to be worn around the neck The unit is waterproof and once armed it can be activated either manually or automatically if submerged in water.  The user-replaceable battery delivers at least 12 hours of continuous transmission and it has a shelf life of 10 years.

While the locator unit is primarily designed to be used as a man overboard locator, is can serve equally well as a lost diver search and location system either in conjunction with the Salcom 12-25 Alarm and Locator Receiver, or by relying on search aircraft.
