Frequently Asked Questions
What is the ALERT Man-Overboard Alarm System?
The ALERT Man-Overboard Alarm System is a marine safety system designed to notify if someone falls unintentionally into water. Because the product works within seconds, it is much easier to locate the Person Overboard (MOB). The ALERT Man-Overboard Alarm System consists of an automatic, water-activated Transmitter and a Receiver. Additionally, a Portable Direction Finder can be utilized to home in on the Transmitter’s transmission.Upon hitting the water, the Transmitter immediately transmits to the Receiver on the boat or shoreside operation, alerting others of a fall overboard. The Receiver sounds an internal siren and can be wired for additional alerting functions. The Receiver can also shutdown the engine of the vessel, and mark a position on a compatible chartplotter system.
What is the difference between the ALERT Man-Overboard Alarm System and and EPIR
The ALERT Man-Overboard Alarm System is a local transmission beacon for the boat and provides quick notification for the fastest rescue because it’s automatic water activation alerts the boat as the MOB is coming up for their first breath of fresh air. An EPIRB is designed to transmit to a satellite which will retransmit a position to the authorities. It may take many hours before a search effort is coordinated.Best way to think of this is, if you know you are going to be leaving your boat (sinking, fire, etc.) an EPIRB is a must have. However, the act of falling in the water is usually not planned and an EPIRB is not the best device for that scenario but the ALERT Man-Overboard Alarm System is.
What is the range of the ALERT Man-Overboard Alarm System?
The ALERT Man-Overboard Alarm System is a “line of sight” Ultra High Frequency (UHF) transmission system. Therefore the range is dependent on antenna placement for the ALERT Receiver and how far the person wearing the ALERT Transmitter is in proximity to the line of sight of the antenna. In most cases, the coverage range is 1,000 to 1,500 feet (300 to 450 meters) without tall buildings or topography between the antenna and the working area of the person working near water. That is why the ALERT Man-Overboard Alarm System is perfect for most vessels and shoreside operations. Once the person falls in the water, the ALERT Transmitter continues to transmit its signal and can be “homed in” by using the ALERT Portable Direction Finder.
Can I extend the amount of alerting devices?
The ALERT2 and ALERT418 Man-Overboard Alarm System Receivers have connections on the back that allow for the wiring of other devices to extend the alerting capabilities of a MOB. Many customers have connected additional external alarms, strobe lights, Internet connected devices, remote dial-up technology, and other solutions that alert both locally and remotely of a fall overboard situation.
Will the ALERT interface with my Chartplotter software?
The ALERT418 Receiver has a serial port and can be connected to Chartplotting software that accepts a NMEA 0183 compliant MOB command. The ALERT2 Receiver has “Normally Open”, “Normally Closed” contacts that can also be wired to various chartplotter software. Contact Emerald Marine Products for specific technical information.
How does the ALERT Man-Overboard Alarm System locate the person in the water?
The ALERT Man-Overboard Alarm System works so quickly that a visual of the person in the water is your best way to locate them. In the event the person does float out of sight, the optional ALERT2 Portable Direction Finder can assist in detection by sweeping the handheld antenna along the horizon. The ALERT2 Portable Direction Finder will pick-up the ALERT Transmitter’s transmission and as the direction finder is pointing in the direction of the person, the rescue skiff can follow the signal. Maximum range is one nautical mile.
How does the ALERT Man-Overboard Ssytem help the single handler?
The shipboard mounted receiver has relay contacts that can be wired into various devices such as an engine shut down or autopilot disconnect. This gives the person in the water a chance to swim back to the boat.
What do I have to do to maintain the ALERT Man-Overboard System?
There is no need for any type of annual certification. We recommend periodic testing (daily, weekly, monthly based on your company’s safety maintenance plan). Proper storage of the unit will greatly extend the product’s lifespan. The ALERT2 Transmitter uses two (2) 3.6 volt replaceable lithium batteries (included) with a 10-year shelf life. The ALERT418 Transmitter uses two (2) CR123A replaceable lithium batteries (included) with a 10-year shelf life. You can arm the Transmitter and leave it in that state for years. Replace the batteries after emergency use.
Who is using the ALERT Man-Overboard Alarm System?
The ALERT Man-Overboard Alarm System is in use by Government Entities, Tug and Tow Boats, Fishing Vessels, Pilot Vessels, Marine Terminals, Fleeting Operations, and Offshore Sailboats. Any company concerned that an accidental fall-in-the-water activity may occur should use our product.
What type of warranty comes with the products?
All ALERT products come with a 3-year parts and labor warranty.

What is the difference between the ALERT2 and ALERT418 Transmitter?
Both the ALERT2(™) and the ALERT418(r) Transmitters transmit to the vessel upon hitting water, immediately notifying the crew of a fall overboard. The ALERT418 is slightly smaller and lighter than the ALERT2. The ALERT418 Transmitter broadcast’s unit identifier information that can be displayed on the ALERT418 Receiver. The ALERT418 Transmitter is slimmer and can be attached within an inflatable personal flotation device, making it even more seamless to wear. The ALERT418 includes a bank of 6 LED lights for illumination when water-activated. Both the ALERT2 and ALERT418 Transmitters work with the ALERT2 and ALERT418 Receivers.
How many ALERT Man-Overboard Transmitters can be used?
There is no limit to the number of transmitters. Every crew member should wear one on their Personal Flotation Device (PFD).
Will the ALERT Man-Overboard Transmitter switch on if I get splashed on deck?
When mounted in its pouch (included), rain and waves splashing against it will not activate the water sensor. However, in conditions where excessive water is around the crew member, for example commercial fishing vessels where pulling lines over shoulder will drip water over the ALERT Transmitter, a Spray-tight pouch is available to protect the ALERT from sending unwanted transmissions. The ALERT418 transmitter is shipped standard with a spray-tight pouch.
Will the ALERT Man-Overboard Alarm work underwater?
Technically the ALERT2 and ALERT418 Transmitters are transmitting underwater but the transmission might not be received by the Receiver if the transmitter is deep in the water. The UHF frequency is based on “line of sight” therefore the higher the transmitter is located (as in held overhead by the person in the water) better reception will occur. This is why a PFD should be worn and the Transmitter mounted high on the PFD.
