TYFON® MKT 75/260 with Valve Unit TV 784

A high–power whistle according to IMO for vessels up to 75 meters in length

General Information
TYFON series MK 75/– of all sizes have always had an efficient sound spectrum fulfilling the highest demands — on vessels as well as in a great many civil defence and disaster alarm stations on land. Their popularity can be summarized in practical terms:
• a sound spectrum which gives excellent signal quality for detection — by several strong penetrating com-ponents,
• a sound generated in a simple classical way giving full strength also under hard and varying environmental conditions.

Positioning Whistles
IMO describes the importance of appropriately positioned whistles. The best solution from all aspects is a combined system with a frequency difference of at least 10 Hz, but preferably more. Good combinations can be chosen with our variants in the MKT 75/– series, e.g. 260 and 440 Hz, 350 and 440 Hz.
For the prescribed all–round sound radiation, funnel or front wall mounting are generally not acceptable when only one whistle is used.

Valve Unit
The VALVE UNIT TV 784 has a good air flow section, thermostatic heating, exchangeable choke flanges and filters. The apparatus is fitted with two coils for normal and emergency operation and lanyard as standard (see separate leaflet KSM 264). .
