FedSig Expansion Module

Master the most complex emergency vehicle upfits by distributing power intelligently with a Federal Signal Pathfinder Expansion Module (EXPMOD). Operating over the proprietary FS Convergence Network, these potted, under-hood capable modules (available in 24-channel and 32-channel configurations) drastically reduce heavy-gauge wire routing. Instead of running dozens of thick cables through the firewall, a single data cable commands the expansion module to execute fully programmable flash patterns, OEM lighting control, and high-amperage accessory switching locally at the front or rear of the vehicle.

Key Features & Upfitter Specs

Scalability: Adds 24 or 32 fully programmable solid-state relay outputs to your core Pathfinder siren and light controller system.
Programming: Every output is entirely customizable via Convergence Network Software for specific flash patterns, dimming, and current limits.
Durability: Fully potted, weather-resistant design allows for secure mounting under the hood, behind grilles, or in exposed rear cargo areas.
Integration: Dramatically reduces installation labor by utilizing serial data connections to execute complex OEM integration (e.g., brake/tail flashing).
Networking: Connect up to four expansion modules to a single Pathfinder system, easily identified via hardware Module Identifier (MID) dials.
