12-25 Man Overboard Alarm and Locator Receiver
The Salcom 12-25 Man Overboard Alarm and Locator Receiver compliments Salcom Man Overboard Locator Beacons and is capable of providing a Man Overboard Alarm system and a Man Overboard Location System in a single device. It can also detect transmissions from most models of Man Overboard Beacons (MOB), Personal Locator Beacons (PLB) and EPIRBS since all of these devices transmit on the same 121.5MHz distress frequency.
The 1225 receiver displays the identification and transmission time of activated Salcom Man Overboard Locator Beacons. It also displays signal strength which can be used to give an indication of the approximate location of an activated Man Overboard Locator Beacon using the direction finding technique described in the user’s manual.
A relay output is provided which can be used to trigger a “Man overboard” or “Engine Kill Switch” on some GPS receivers. An input for an external GPS receiver is available so that GPS coordinates can be automatically displayed when a MOB locator beacon is activated.
This data is retained as a GPS reference to the position of the vessel at the time the initial man overboard emergency transmission was received. The vessel can then turn about and proceed back to that location.
The small receiver can be hand held or bracket mounted. It has an easy to read LCD display and is both mains and battery powered.
Since the frequency of the MOB Locator Beacon transmission is the same as the homing transmitter of an EPIRB, it can also be used by Search and Rescue to pinpoint a survivor.
