Marine Electric Horn (STORM-7300)

STORM-7300 Electric Marine Horn incorporates three main functions, marine horn, cabin interphone and general alarm. It has advantages of high acoustic pressure, comprehensive functionality, high reliability, long service life and simple installation.

The high power electric horn is able to make 131 dB @1m acoustic pressure to achieve one nautical mile effective audibility range. It is applied for vessel over 20 meters but under 75 meters in length. It can work under serious marine environments with excellent outdoor performance, anti-water/dust (IP56), corrosion and high-low temperature resistance. Patent No. ZL201020522870.2, ZL201030282705.

With integrated chip control, the horn makes stable frequency sound. It incorporate a push 'at-will' button to produce blast manually. Besides there is one automatic fog horn button, which can produce prolonged and short blast codes repeatedly according to IMO/SOLAS requirement. The hand-held microphone can make PA talk both outward sea and interphone talk between navigation bridge and cabins. It incorporate one general emergency alarm button, which can make emergency alarm sound both on the horn and cabin interphone speakers under emergency situation.

(C)PA Talk Outward
When 'Transfer Switch' on 'Horn', we can use the microphone to make PA talk outward sea.

2. Cabin Speaker Operation
Turn 'Transfer Switch' to 'Cabin Speaker', then the electric horn will be turned off.

When 'Cabin Speaker I' button light on, we can use the microphone to talk to concering cabin, the sailor in cabin can also reply to navigation bridge through direct talking to cabin speaker without other operation, the sound will be played by internal speaker in control amplifier.
