SCS–1002 system is designed to be installed at the seagoing and river vessels to provide in–call annunciation from a button console to the watchman post which may be transmitted from refrigerator chambers, ship’s hospital and other facilities and premises with restrictions of [hindered] mobility where a certain level of danger implies.
Primary system characteristics
No. in–call posts controlled 1 / 5 / 10 / 32
Maximal no. of in–call posts included up to 128 (max. 32 simultaneously displayed on the screen)
Power supply voltage
  • 24 (18–36) VDC – for system devices;
  • 24 VDC or 220 VAC, 50 Hz – for annunciation devices.
Integral protection of the system devices
