When any subscriber on the switch is turned on, a call from another subscriber is provided with a short tone or intermittent light of normal duration. When transmitting, the call is only provided by a discontinuous light signal. Set No. 2 has a wide range of operating temperatures, withstands the effects of salt fog. Some elements have a high degree of protection against water IP55.
The equipment of "OKA" meets the requirements of the Russian River Register and is suitable for installation on passenger ships.
The most frequently used places for the installation of equipment "OKA":
The main deck is the central span,
Right / left boards;
Buck / feed;
Devices of equipment, depending on the location of their installation, have the following degrees of protection:
IP20 for devices installed in dry rooms (BPU-50, SSCK2);
IP44 for instruments installed near the front wall of the wheelhouse (K-10S);
IP55 for instruments installed on the open decks of the ship and in noisy rooms (SSCH2, 10GR-D4.01KT, SSCH-2C with a luminaire).
