Your purchase of a Wolo OCEAN ALERT

Air Horn will complement your boat while offering an extra

level of protection. Wolo’s products are manufactured with the ﬁnest materials. Each horn is tested to ensure

it meets all of our manufacturing speciﬁcations, before being packaged. If you need help installing your new

Wolo horn, our technicians are available to answer your questions, Monday thru Friday, 9 AM to 4 PM EST

at 1-888-550-HORN (4676).

Before installation of the horn is attempted, it is important to read these instructions completely. The lives of

people can be dependent on a proper installation of the horn. The person doing the installation must have

knowledge of the proper method for mounting and securing the horn to the exterior of the boat as well as

knowledge of the boat’s electrical system. Again, read the instructions completely and note any messages

marked “IMPORTANT” or “WARNING’’. A safe installation will prevent injury or damage to the boat.

WARNING: Installation of the OCEAN ALERT requires drilling. The installer must carefully inspect both sides

of the selected mounting locations to ensure that there are no wires, fuel line and or any other components that

could be damaged by drilling.

WARNING: If any wires are routed through drilled holes; always de-burr ensuring that there are no sharp

edges. Install a rubber grommet into all metal holes that wires are being routed through.

MOUNTING TRUMPET: Fig. 1

IMPORTANT: The horn should be mounted

facing forward whenever possible. The NMMA

Certiﬁcation Program requires this for boats 39’

or longer.

1. Locate the desired mounting location of the

trumpet. For best results, the front of the horn

should be unobstructed so that the sound can

carry straight ahead.

IMPORTANT: FOR BEST PERFORMANCE

AND SOUND, ALWAYS MOUNT THE

COMPRESSOR CLOSE TO TRUMPET,

KEEPING THE HOSE LENGTH AS SHORT

AS POSSIBLE. THE COMPRESSOR

MUST BE MOUNTED IN A DRY INTERIOR

LOCATION).

2. Use the horn’s gasket as a template, mark

hole locations and drill to size.

3. Thread the two chrome air inlet tubes into the base of the horn.

4. Mount and secure the horn as shown in Fig. 1.

IMPORTANT: Be sure to use the rubber gasket provided to protect against water leaks. Tighten the base plate

nuts that thread onto air inlet tubes evenly to ensure a watertight seal.

The Wolo Model 160-24 OCEAN ALERT® MINI is a 24-volt air horn system designed for marine use, offering both a functional horn and an added layer of safety for boats. Manufactured with high-quality materials, each horn undergoes rigorous testing to ensure it meets Wolo's manufacturing specifications before packaging. Wolo provides technical support for installation questions, available Monday through Friday, 9 AM to 4 PM EST, at 1-888-550-HORN (4676).

Function Description:

The OCEAN ALERT® MINI is an air horn system that produces a loud signal for marine vessels. It is designed to meet various maritime regulations and standards, including the U.S. Coast Guard's C.O.L.R.E.G.S. and U.S. Inland Navigation Rules, Annex III, for boats up to 20 meters (65 ft). It is also "type accepted" by the National Marine Manufacturers Association (NMMA) and meets the American Boat & Yacht Council (ABYC) A-23 standard for boats up to 20 meters (65 ft). The system comprises a trumpet (horn), a compressor, air inlet tubes, plastic tubing, a "Y" connector, a rubber gasket, and a relay. The horn's primary function is to provide an audible warning signal, crucial for safe navigation and compliance with maritime regulations.

Important Technical Specifications:

Voltage: 24-volt system.
Fuse Requirement: A 15-amp inline fuse is required to protect the electrical circuit. This fuse must be connected directly to the power source.
Wire Gauge:
- Relay terminal 87 to compressor's positive (+): 16-gauge wire or heavier.
- Horn switch to negative (-): 18-gauge wire or heavier.
- Relay terminals 30 & 86 to positive (+) 24-volts: 16-gauge wire or heavier.
- Relay terminal 87 to compressor's positive (+): Not less than 16-gauge wire.
- Compressor's negative (-) to boat's negative (-): Not less than 16-gauge wire.
Compressor Mounting Distance: The compressor should not be mounted further than 30 inches from the trumpet for optimal sound performance.
NMMA Certification: The NMMA Certification Program requires the horn to be mounted facing forward for boats 39 feet or longer.

Usage Features:

Installation: The installation process involves mounting the trumpet and the compressor, followed by electrical wiring.
- Trumpet Mounting: The horn should be mounted facing forward whenever possible, with its front unobstructed to allow sound to carry straight ahead. A rubber gasket is provided to ensure a watertight seal during mounting. The two chrome air inlet tubes are threaded into the base of the horn.
- Compressor Mounting: The compressor must be installed in a dry interior location. For best performance and sound, it should be mounted as close to the trumpet as possible, ideally within 30 inches, with the air outlet on top.
- Air Tubing: Plastic tubing connects the compressor to the horn's two air inlets via a "Y" connector. It is crucial to avoid kinks or sharp bends in the tubing, as this can reduce airflow and alter the horn's sound. The tubing should be kept as short as possible.
Wiring Options:
- New Horn Button Switch: This method involves installing the provided relay close to the compressor. Relay terminal 87 connects to the compressor's positive, terminal 85 to a new horn button switch (not provided), and the switch's other terminal to a negative (-) source. Terminals 30 and 86 connect to a positive (+) 24-volt source, protected by the 15-amp inline fuse. The compressor's negative (-) terminal connects to the boat's negative (-) battery post.
- Boat's Factory Horn System (Two-Wire System): This method utilizes the boat's existing horn wiring. The provided relay is essential to protect the factory horn button switch and wiring, as the original factory horn draws less amperage. The two wires from the factory horn are removed. Relay terminal 85 connects to one factory horn wire, and terminal 86 connects to the other. Terminal 30 connects to a positive (+) 24-volt source with the 15-amp inline fuse. Terminal 87 connects to the compressor's positive, and the compressor's negative connects to the boat's negative (-) battery post.
Safety Warnings:
- Thoroughly read all instructions before installation, as proper installation is critical for safety.
- The installer must have knowledge of proper mounting techniques and the boat's electrical system.
- Inspect both sides of selected mounting locations for wires, fuel lines, or other components that could be damaged by drilling.
- If wires are routed through drilled holes, de-burr the holes and install rubber grommets to prevent damage to the wires.
- Always test the horn signal system before using the vessel to ensure it is functioning at peak performance. A working horn signal system is vital for the safety of all on board.

Maintenance Features:

Warranty: Wolo Manufacturing Corporation provides a twelve-month warranty from the date of purchase, covering defects in workmanship and materials. If a defect is proven, Wolo will repair or replace the item free of charge, provided it is returned within the warranty period with proof of purchase.
Warranty Exclusions: The warranty does not cover damage due to fire, casualty, accident, neglect, abuse, abnormal use, modifications, faulty installation, or natural causes.
Obtaining Warranty Service: To obtain service, the product must be returned prepaid with the original bill of sale, a brief description of the problem, and a check or money order for $10.00 to cover return shipping. Returns should be sent to Wolo Manufacturing Corp., One Saxwood Street, Deer Park, NY 11729, Attn: Warranty Service. Technical support can also be reached via email at tech@wolo-mfg.com.
Watertight Seal: The rubber gasket provided for trumpet mounting helps protect against water leaks, ensuring the longevity of the horn system. Evenly tightening the base plate nuts onto the air inlet tubes is crucial for maintaining this seal.
