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. Before being packaged, each horn

is tested to ensure it meets all of our manufacturing speciﬁcations. 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 lines 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 & 2

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.

5. Position the front trumpet support bracket around the narrow

part of each trumpet. Push the bracket forward until it is tight.

Using the bracket as a template, mark hole locations and drill

to size, see ﬁg 2.

6. Secure the front trumpet support bracket using the hardware provided. Tighten screw to ensure a watertight

seal.

IMPORTANT: Provided in the kit are two soft rubber strips that are placed into the ring of the support bracket to

provide a tight ﬁt and prevent vibration. Be sure to use the rubber gasket provided to protect against water leaks.

The Wolo Model 170 OCEAN ALERT® is a 12-volt air horn designed for marine use, providing an extra level of protection for boats. It is manufactured with high-quality materials and undergoes testing to ensure it meets manufacturing specifications.

Function Description:

The OCEAN ALERT® air horn produces a loud sound for signaling and safety on the water. It operates using a compressor that forces air through two trumpets. The horn is designed to be mounted on the exterior of a boat, with the compressor installed in a dry interior location. It can be integrated with a new horn button switch or connected to a boat's existing factory horn system (two-wire system) using a supplied relay.

Important Technical Specifications:

Power Requirement: 12-volt DC.
Fuse Requirement: A 20-amp inline fuse is required for the power circuit, connected directly to the power source.
Wire Gauge (Compressor to Relay): 16-gauge or heavier for positive (+) and negative (-) connections.
Wire Gauge (Relay to Horn Switch): 18-gauge or heavier.
Compressor Mounting Distance: Must be installed no further than 30 inches from the trumpet for optimal sound performance.
Compliance:
- Meets U.S. Coast Guard's C.O.L.R.E.G.S. and U.S. Inland Navigation Rules, Annex III Regulations for boats up to 20 meters / 65 ft.
- NMMA (National Marine Manufacturers Association) "type accepted."
- Meets American Boat & Yacht Council (ABYC) A-23 standard for boats up to 20 meters / 65 ft.

Usage Features:

Mounting:
- Trumpet: Should be mounted facing forward whenever possible, with the front unobstructed for optimal sound projection. A rubber gasket is provided to ensure a watertight seal when mounting to the surface. Two chrome air inlet tubes thread into the horn's base. A front trumpet support bracket is used to secure the trumpets, with soft rubber strips inserted into the bracket ring to prevent vibration and ensure a tight fit.
- Compressor: Must be installed in a dry interior location, close to the trumpet (within 30 inches) for best performance. It can be mounted vertically with the air outlet on top. A 3/16" hole is drilled for securing the compressor using a bolt, lock washer, and nut.
Air Tubing: Plastic tubing connects the compressor to the two air inlets via a "Y" connector. It should be cut to size and kept as short as possible. Kinks or sharp bends must be avoided to prevent reduced airflow and altered horn sound.
Electrical Connections:
- New Horn Button Switch (Fig. 5):
  - A horn relay is provided and must be installed in a dry interior location with terminals facing downward.
  - Relay terminal 87 connects to the compressor's positive (+) terminal.
  - Relay terminal 85 connects to the horn button switch (not provided).
  - The horn switch's other terminal connects to a negative (-) source (battery post or clean metal surface).
  - Relay terminals 30 & 86 connect to a positive (+) 12-volt source (battery, alternator, fuse block) with a 20-amp inline fuse, connected directly to the power source.
  - The compressor's negative (-) terminal connects to the boat's negative (-) battery post or a clean metal negative surface.
- Factory Horn System (Two-Wire System) (Fig. 6):
  - The supplied relay must be used to protect the factory horn button switch and wiring.
  - The two wires from the factory horn are removed.
  - Relay terminal 85 connects to one factory horn wire.
  - Relay terminal 86 connects to the other factory horn wire.
  - Relay terminal 30 connects to a positive (+) 12-volt source (battery, alternator, fuse block) with a 20-amp inline fuse, connected directly to the power source.
  - Relay terminal 87 connects to the compressor's positive (+) terminal.
  - The compressor's negative (-) terminal connects to the boat's negative (-) battery post or a clean metal negative surface.
Safety Warnings:
- Thoroughly read all instructions before installation.
- Carefully inspect mounting locations for wires, fuel lines, or other components that could be damaged by drilling.
- De-burr all drilled holes and install rubber grommets if wires are routed through metal holes.
- Ensure the 20-amp inline fuse is connected directly to the power source.
