This HURRICANE built-in electropneumatic horn with integrated compressor from Marco is the HR1 model in a white finish for 12 V DC. The horn is designed for flush mounting in a bulkhead, panel, or cabinet and delivers a sound pressure of 120 dB(A) at 1 meter.
The compressor is built into the horn, so the signal is emitted immediately upon activation via an electrical push-button. The design requires no separate air hose between the horn and compressor. The sound frequency is 300 Hz, providing a characteristic low, maritime tone.
The front grille is made of white ASA plastic, while the mounting bracket is made of steel. The mounting/horn dimension is 202 × 120 mm. Since overall dimensions may vary between technical documents, the available mounting space and cutout should be verified before installation. The mounting assembly includes a diaphragm, gasket, and Ø 5.5 mm fastening holes.
The electrical installation must be performed with correct polarity and 90° Faston terminals. For 12 V, a 6 mm² cable is recommended for cable runs up to 10 meters and 10 mm² for cable runs up to 20 meters. The horn is specified at 18 A with a maximum current of 20 A. The installation must be secured with a 25 A slow-blow fuse and a 30 A relay.
The HR1 is NMMA Type Accepted with code 2521490 in the category for horns for boats between 5–12 meters. Applications include pleasure boats, commercial vessels, ferries, and inflatable boats.
The manufacturer number is 13408012, while M134-080-12 appears as an older alternative cross-reference. The complete white grille set R3500002 is available as a documented spare part. The Marco R4M relay with manufacturer no. 12000002 is a documented accessory for the installation; it is not confirmed that the relay is included.
