REV 1
The Tyco LIM800 is a Line Isolator Module PCB designed for use within marine fire alarm systems. Its primary function is to isolate faults on an addressable detection loop, preventing a short circuit from disabling the entire loop and ensuring that the remainder of the system continues to operate normally. This makes it a critical component in maintaining the reliability and continuity of fire detection coverage onboard, in full support of SOLAS fire safety requirements.
Key Features
✓ Functions as a loop fault isolator, automatically disconnecting a short-circuited section of the detection loop while keeping the rest of the system fully operational.
✓ Technical specifications including operating voltage, response time, and physical dimensions are subject to confirmation based on configuration and installation context.
✓ Designed for compatibility with Tyco LIM800-series fire alarm panels and addressable loop architectures; system compatibility should be verified against the specific panel installation.
✓ Suitable for installation within fire alarm loop wiring throughout the vessel, including accommodation, machinery spaces, and other monitored areas as required by the system design.
✓ A direct replacement PCB assembly (ASSY 125.585.931, REV 1) supporting maintenance and service continuity for existing Tyco fire alarm installations.
Marine Applications
✓ Addressable fire detection loops aboard commercial cargo vessels, tankers, and bulk carriers where loop integrity is critical to operational safety.
✓ Passenger vessel fire alarm systems where continuous loop monitoring across multiple zones is required to meet flag state and classification society standards.
✓ Offshore platforms and FPSOs utilising Tyco fire alarm infrastructure across complex, multi-zone detection networks.
✓ Naval and government vessels requiring robust, fault-tolerant fire detection systems with reliable loop isolation capability.
✓ Fire alarm system retrofit and upgrade projects where original Tyco LIM800 module PCBs require like-for-like replacement to restore system performance.
Why Marine Engineers Choose
Marine engineers specify the Tyco LIM800 Line Isolator Module PCB because it provides dependable loop fault isolation that protects the integrity of the entire fire detection system — minimising the risk of widespread alarm failure caused by a single wiring fault, and reducing system downtime during maintenance and repair operations.
Ideal For
Commercial cargo ships, passenger ferries, tankers, bulk carriers, offshore platforms, FPSOs, and any vessel or installation operating a Tyco addressable fire alarm system requiring reliable loop isolation and system continuity.
