Federal Signal EXPMOD24 & EXPMOD32 Programmable Expansion Modules

The Federal Signal EXPMOD24 and EXPMOD32 Expansion Modules provide additional programmable lighting control capabilities for emergency vehicles equipped with compatible Federal Signal siren and light control systems. Designed for police, fire, and other response vehicles, these modules simplify complex lighting installations by distributing control throughout the vehicle while reducing the need for separate flashing equipment.

Expanded Lighting Control

The EXPMOD24 provides 24 programmable solid-state relay outputs, while the EXPMOD32 increases capacity to 32 outputs. Each output supports up to 2.5 amps, with maximum combined ratings of 30 amps for the EXPMOD24 and 40 amps for the EXPMOD32.

Both modules support programmable flashing patterns, steady operation, and dimming, allowing installers to customize connected lighting equipment according to the vehicle's operational requirements.

Advanced Vehicle Lighting Integration

The EXPMOD24 features diode-protected inputs that support OEM LED brake light flashing. The EXPMOD32 provides additional functionality through three diode-isolated relays, supporting brake and taillight flashing or rear lighting blackout functions without requiring a separate taillight flasher.

FS Convergence Network Compatibility

Both modules integrate with compatible Federal Signal siren systems through the FS Convergence Network. Using Federal Signal's Convergence Network Configuration Software, installers can configure output behavior, current limits, and lighting functions. The EXPMOD24 is designed for Pathfinder systems, while the EXPMOD32 also supports compatible FSJoin-equipped systems.
