Testing ALERT Transmitters

We offer step-by-step instructions to test the transmitter on your ALERT Man-Overboard Alarm System as part of your regular man-overboard procedure drills. When you regularly test the transmitter, you increase your chances of a successful man-overboard rescue procedure.

Testing the ALERT2 Transmitter

  1. Arm the ALERT2 Transmitter by turning the cap clockwise until the cap is closed tight. Failure to close completely may allow water to enter electronics compartment and damage the unit.

  2. Immerse the ALERT2 Transmitter in a bucket of water, or wet fingers and touch both metal probes on Transmitter. One of the metal probes is located inside the black nylon boot.

  3. A green LED will light up, indicating that transmission to the ALERT2 Receiver has begun. The green LED will continue to flash in intervals until the Transmitter is unarmed. The Receiver will produce an audible sound once transmission has begun.

    If it doesn’t, make sure the cap is firmly screwed shut. If the cap is firmly screwed shut but the green LED does not flash, nor the alarm sound from the Receiver, contact Emerald Marine Products.

    If the green LED does flash but the ALERT2 Receiver does not sound the alarm, make sure the Receiver is turned on. If the power is on but the Receiver fails to alarm (a red LED on front panel will also light up), contact us. 

  4. The ALERT2 Receiver will continue to sound its Alarm until it’s turned off with the power switch. The ALERT418 Receiver Alarm can be silenced, but will continue to display fall overboard information from an ALERT Transmitter until the Transmitter is reset and the ALERT418 Receiver is powered off. 

  5. Disengage the ALERT2 Transmitter alarm transmission by unscrewing cap until the green LED light stops flashing. Make sure the unit is wiped dry if unscrewing the cap completely (in the event of changing batteries).

  6. If testing additional ALERT2 Transmitters, power off the ALERT2 Receiver and repeat procedures 1-5.

Testing the ALERT418 Transmitter

  1. The ALERT418 Transmitter is in active mode at all times. There is no need to take additional steps to arm the unit.

  2. Immerse the ALERT418 Transmitter in a bucket of water, or wet fingers and touch both metal probes in-line with the 'Reset' button.

  3. Flashing green and red LEDs followed by white LEDs indicate active transmission to the ALERT2 Receiver. The Receiver will produce an audible sound once transmission has begun.

    If only the red LED flashes, replace the unit’s batteries.

    If white LEDs fail to flash, contact Emerald Marine Products.

  4. The ALERT2 Receiver will continue to sound its Alarm until it’s turned off with the power switch. While the ALERT418 Receiver Alarm can be silenced, it will keep displaying fall overboard information from an ALERT Transmitter until the Transmitter itself is reset and the ALERT418 Receiver is turned off.

  5. To stop transmission, press the 'Reset' button on the Transmitter.

  6. If the ALERT418 Transmitter fails to reset, make sure the two metal probes on the cap of the transmitter is dry and press the 'Reset' button for a longer amount of time. If this fails to reset the device OR a red LED flashes, contact Emerald Marine Products.
  7. If testing additional ALERT418 Transmitters, power off the ALERT2 Receiver and repeat procedures 1-5.
