Notifier N100-ISO. Fault Isolator Module.

Notifier N100-ISO Fault Isolator Module

The Notifier N100-ISO Fault Isolator Module enhances the reliability of addressable fire alarm systems by protecting the signaling line circuit (SLC) from short circuits. This module automatically detects and isolates faults, preventing a single wiring failure from disabling the entire loop. It is ideal for installations where system continuity is critical, such as hospitals, schools, airports, and commercial buildings.

By maintaining uninterrupted communication across the rest of the loop, the N100-ISO ensures faster diagnostics and minimal disruption during emergencies.

Reliable Fault Isolation for Addressable Loops

The N100-ISO continuously monitors the SLC for short circuits. When a fault is detected, the module immediately isolates the affected segment, allowing the remaining loop to continue functioning. This automatic action helps the fire alarm system remain operational while isolating the issue for later repair.

Once the fault is cleared, the module automatically restores the loop to its normal condition, eliminating the need for manual resets.

Seamless Integration and Compatibility

Designed for use with Notifier intelligent fire alarm control panels, the N100-ISO integrates directly into the SLC. It occupies one address but does not use up any of the device addresses on the loop, preserving capacity for other modules or detectors. Installers can position the module between every 15 to 20 devices, following system design guidelines to ensure proper loop segmentation.

Because of its plug-in design and LED status indicator, the module simplifies both installation and troubleshooting.

Compact Design and Flexible Mounting

The Notifier N100-ISO features a compact, low-profile housing suitable for mounting in standard 4-inch electrical boxes. Its durable construction supports long-term reliability in various indoor environments. In addition, its front-facing LED provides visual confirmation of normal operation or isolation mode, allowing for easy identification during maintenance checks.

Technicians can quickly access wiring terminals, which helps speed up installation and reduces setup errors.

The Notifier N100-ISO Fault Isolator Module plays a crucial role in protecting intelligent fire alarm systems from wiring faults. With its automatic short-circuit isolation, compact design, and compatibility with Notifier addressable panels, it ensures system resilience and operational integrity. For any project where uninterrupted communication is essential, this module provides the fault tolerance required to keep safety systems active and reliable.
