Engine Protection with Automatic Fire Suppression

Rear or enclosed combustion engine spaces concentrate heat, fuel, and moving components. This, paired with intensive operations, make them a primary fire risk area on vehicles.

Protect the critical engine compartment with a fully integrated Firetrace system, combining reliable heat detection with proven automatic suppression.

What's the Risk?

Fluid Leaks

Fuel, oil, and hydraulic fluids can escape from worn hoses or fittings and accumulate within the engine compartment. When these flammable liquids contact hot surfaces, they can ignite and spread rapidly.

High Engine Temperatures

Engines generate significant heat during normal operation, with components like exhaust manifolds and turbochargers reaching extreme temperatures. These hot surfaces can ignite nearby fluids or debris without warning.

Heavy Vibration

Constant vibration during operation can loosen fittings, damage wiring, and accelerate wear on critical components. Over time, this increases the likelihood of leaks or electrical faults that can lead to fire.

Solutions Overview

Firetrace systems are designed to detect and suppress fires at the source, quickly and reliably.

How It Works:

Engine Protection with LHD

DETECT

Heat from a fire is detected by the LHD cable, triggering a electric signal that is immediately sent to the control module.

ACTIVATE

The control module alarms, checks for programmed delays or manual inputs, then signals the valve solenoid to release system pressure.

SUPPRESS

The suppression agent is discharged through system nozzles, quickly blanketing the protected area to suppress the fire at its source.

More on LHD

Linear Heat Detection provides continuous monitoring along the full length of the cable. When a fire occurs, heat melts the insulation, the wires touch, and a signal is sent to trigger the system discharge.

Installed throughout the hazard area, LHD delivers fast, accurate detection where traditional methods may be challenged.

Firetrace sources LHD directly from sister company Thermocable, bringing you more tailored solutions without compromising performance.

New Control Module

The Firetrace Control Module provides clear, reliable system management in one compact interface. Built-in driver controls simplify operation while offering complete visibility into system status and readiness.

When the LHD wires touch, it receives the detection signals, coordinates system response functions, and helps ensure fast, reliable system activation.

Module includes integrated test modes, reset, mute, system delays, and manual release functions, helping operators respond quickly and confidently when it matters most.
