OSSH is a system of handles for fire doors which light up to be detected in critical conditions and provide informations such as emergency indicating escape routes with the color of light.OSSH interacts with external systems (FDS,ESD, SMS,SMCS) via communication protocols such as modbus.Ossh is a truly smart handle: the management electronics are placed in the ceiling in a special junction box, wired with a BUS485 system that carries a network signal throughout the vessel and power supply to the handle through the lock clash. It is simply installed, even in the case of retrofitting, as an unambiguous safety means of hazard communication via BUS485.
The system is designed for use on board naval units - yachts, platforms and terminals; everywhere there is a need to also have ATEX certification (ships with alternative fuels such as F.C., LNG, Hydrogen, ammonia ) .The system integration" with the FDS – GAS Detection – LLL system is practicable, approaching the matter also with a risk analysis from which emerge that the systems are "additional / additional" and can be an added value for scenario cases such as evacuation / emergency related to security.
Our company is leading manufacturer of locks for marine fire doors and OSSH system is provided in kits which do not vary in size and shape from the standard ones.This makes it quite easy retrofit, adding important safety tools on any existing ship; ship owners can improve safety onboard their vessels by simply fitting OSSH kits on their ships' firedoors. OSSH handles represent a system of mitigation of spread risk for pathogenic agents; a benefit to shipowners, passengers and crew , in compliance wit Rina's additional note of Classe BIOSAFE SHIP with reference to “Surfaces with high utilization rate active materials”.
