(((•))) Kockum Sonics with Valve Unit TV 784 A high-power whistle according to IMO for vessels 200 m or more in length General Information Nowadays, each vessel from 12 metres and more (length overall) must be equipped with sound signal appliances which are type approved according to the IMO regulations. Hence, one part of the responsibility Is the manufacturer's, but still one Important part Is the shipowner's regarding the choice of appropriate equip- ment for the vessel In question, the Installation and use. The reason behind the stipulated use of 1/3 octave band filters when measuring Is connected to the theory of the hearing sense. A "complex" sound like that from TYFON® or SUPERTYFON consists of several harmonic com-ponents. Consequently, the total SPL value Is considerably higher than the measured (sti- pulated) 1/3 octave value. Positioning Whistles For an all-round radiation and a limited noise level from the ship's whistles at the listening posts, the positioning of the ship's whistles Is very Important. For further Information regarding In- stallation regulations and "Combined Systems", see our leaflet Valve Unit The VALVE UNIT TV 784 has a good air flow section, ther- mostatic heating, exchangeable choke flanges and filters. The apparatus Is fitted with two colls for normal and emergency operation and lanyard as standard (see the separate leaflet Valve SUPERTYFON MKT 150/110 Is to be fixed with four M16 bolts toan outrigger or similar construction. To avoid functional trouble blow the supply pipe thoroughly clean before connecting to the signalling whistle. If the pipe line above deck Is longer than 100m, a primary FILTER TP 15/2 should be Installed at the foot of the mast to protect the signalling apparatus from water condensate and rust particles. This filter Is recommended to be drained regularly, approximately Technical Data Sound Pressure Level (1m): Air supply pressure with choke regulation: Electric power:
