Description
CONSILIUM AB.
ISOLATOR-A
PART NO: N1790
IS ISOLATOR
INTRINSICALLY SAFE ISOLATOR
4 -24.8 VDC E
The Consilium N1790 Isolator-A is an intrinsically safe isolator designed for use within marine fire alarm systems. Its primary function is to isolate sections of a detection loop in the event of a short-circuit fault, preventing a single wiring fault from disabling the entire loop. This makes it a critical component in maintaining the integrity and continuity of fire detection coverage onboard vessels, directly supporting life safety and SOLAS compliance requirements.
Key Features
✓ Functions as an intrinsically safe loop isolator, automatically isolating short-circuit faults on the detection loop while keeping the remainder of the loop fully operational.
✓ Operating voltage of 4–24.8 VDC as indicated in the product data; additional electrical ratings are subject to confirmation against the specific installation configuration.
✓ Compatible with Consilium fire alarm and detection systems; exact panel and controller compatibility should be verified against system documentation prior to installation.
✓ Designed for mounting within fire detection loop wiring runs in both hazardous and non-hazardous areas typical of marine environments, supporting intrinsically safe circuit requirements.
✓ Suitable as a direct replacement part within existing Consilium fire alarm installations, helping to restore loop fault tolerance and minimise system downtime during maintenance.
Marine Applications
✓ Cargo vessels and bulk carriers where fire detection loops cover large deck areas and fault isolation is essential to maintain zonal coverage.
✓ Offshore platforms and support vessels requiring intrinsically safe equipment in or near potentially hazardous atmospheres.
✓ Passenger ferries and cruise ships where continuous fire alarm loop integrity is mandatory under flag state and SOLAS regulations.
✓ Tankers and chemical carriers where intrinsically safe fire detection components are specified throughout hazardous zone wiring systems.
✓ Naval and specialist vessels with complex fire detection networks where loop isolators are installed at regular intervals to contain wiring faults.
Why Marine Engineers Choose
The Consilium N1790 Isolator-A is a trusted isolator component within Consilium fire alarm installations, valued for its role in maintaining loop resilience and ensuring that a single point of failure does not compromise fire detection across an entire vessel zone.
Ideal For
Suitable for cargo ships, tankers, offshore vessels, passenger ferries, and any commercial or specialist vessel operating a Consilium fire alarm system that requires intrinsically safe loop isolation.
Technical Support
Technical support is available for the Consilium N1790 Isolator-A covering onboard installation guidance, fault diagnosis, and remote troubleshooting. Assistance can be provided to help engineers integrate or replace this isolator within existing fire alarm loop configurations.
