Description
AUTRONICA
DZZ-2/10
DIODE SAFETY BARRIER PCB CARD
The Autronica DZZ-2/10 is a diode safety barrier PCB card designed for use within marine fire alarm systems. Safety barriers of this type serve a critical role in intrinsically safe circuit designs, limiting the energy that can pass into a hazardous area loop and thereby preventing ignition sources from reaching flammable atmospheres. In the context of onboard fire detection, this card helps maintain safe and reliable signal transmission between the fire alarm control panel and field-mounted detectors, particularly in zones where explosive or flammable atmospheres may be present. Operational integrity of the fire alarm system depends on the correct functioning of components such as this barrier card.
Key Features
✓ Functions as a diode-type safety barrier, restricting fault energy from reaching hazardous area detector circuits — a fundamental requirement in intrinsically safe fire alarm loop designs.
✓ Specific voltage, current, and power ratings are subject to confirmation against the original system documentation; performance characteristics are typical of Autronica barrier components used in this product family.
✓ Designed for compatibility with Autronica fire alarm system architectures; exact panel or controller compatibility should be verified against the installed system configuration.
✓ Typically installed within the main fire alarm cabinet or a dedicated barrier mounting assembly in a safe area; installation context and mounting arrangement depend on vessel configuration.
✓ As a PCB-level component, replacement should be carried out by qualified personnel following Autronica service procedures; correct handling of static-sensitive components is essential during installation.
Marine Applications
✓ Fixed fire detection systems aboard tankers, gas carriers, and other vessels where intrinsically safe detector loops are required in hazardous or classified zones.
✓ Engine room and machinery space fire alarm circuits where isolation of field wiring is necessary to meet safety system integrity requirements.
✓ Cargo hold and pump room detection loops on chemical tankers and LPG or LNG carriers where explosive atmosphere protection is mandated.
✓ Offshore support vessels and platform supply vessels operating fire alarm systems in environments subject to strict hazardous area classifications.
✓ Retrofit and maintenance scenarios where an existing Autronica fire alarm system requires barrier card replacement to restore full system functionality.
