Fire detection and thermal monitoring
Earlier detection for safer transit fleets
Detection technologies for vehicles, facilities, and critical assets
Earlier detection gives transit personnel more time to evaluate a threat, protect passengers, and prevent a manageable thermal event from becoming a destructive fire. Troman brings together optical, gas, linear heat, terminal lug, and thermal imaging technologies to monitor the areas where vehicle fires are most likely to begin.
These detectors work alongside control panels, dataloggers, displays, and notification systems to identify abnormal conditions and communicate actionable information. From engine compartments and battery enclosures to charging infrastructure and maintenance facilities, Troman, Trident, Protectowire, and moviTHERM solutions provide layered monitoring designed around the realities of modern transit operations.
Troman’s transit fire detection and thermal monitoring solutions identify abnormal heat, flame, gas, and electrical conditions early so fleets can respond before a developing threat becomes a destructive fire.
Put thermal monitoring inside the spaces where heat develops.
Compact dual-vision imaging for enclosed transit applications
The TNC20 combines calibrated thermal imaging and visible video in a low-profile housing designed for enclosed spaces. Its wide field of view makes it suitable for compact equipment areas, battery enclosures, electrical compartments, and other locations where installation space is limited.

Give the operator an immediate way to act.
Protected manual activation for Troman suppression systems
The Troman manual fire switch gives the vehicle operator direct control of the extinguishing system during an emergency. Installed within reach of the driver, the protected FIRE button can immediately activate suppression and the emergency outputs configured through the Troman controller.
A tamper seal and lift cover help prevent accidental operation while keeping the activation sequence straightforward under pressure. The switch is compatible with Troman multifunction controllers.
The Troman manual fire activation switch allows a bus operator to immediately trigger the vehicle suppression system and configured emergency protocols from the driver compartment.
Simple operation when time is limited
Break the seal, lift the cover, press FIRE.
The activation sequence is intentionally direct. Once operated, the switch sends the manual alarm condition to the controller, which carries out the configured suppression and vehicle response.
A manual layer within an automatic system
Operator control complements automatic detection.
Automatic detectors may identify conditions the operator cannot see, while the manual switch allows the operator to act on visible smoke, flame, or other urgent information. Used together, they provide separate paths to initiate the response.

Resettable linear temperature sensing for demanding vehicle areas
The Troman Terminal Lug Sensing Element provides robust, resettable temperature detection along extended or irregular vehicle hazard zones. The sensing element can be routed around multiple risk points and connected through installation components to a dedicated TLSE control module.
As the element is exposed to elevated temperature, its resistance decreases. When the configured alarm resistance is reached, the module sends an alarm to the Troman controller. The sensor is powered from both ends so it can continue operating through certain types of physical damage.
The Troman Terminal Lug Sensing Element provides resettable heat detection along extended vehicle hazard zones and sends an alarm through its control module when the sensing element reaches the configured condition.
Continuous sensing across the routed element
Monitor more than a single point.
The TLSE can follow the shape of the protected area and respond when the full length or a shorter section is exposed to elevated temperature. This makes it useful around components and spaces where a point detector may not provide sufficient coverage.
Designed to remain useful in a harsh zone
Dual-ended power supports a resilient detection path.
The element is intended for high-temperature vehicle environments and is assembled with Troman installation parts. Available lengths allow the system to be fitted to the geometry of the application.

Troman optical detection for high-risk vehicle zones
Troman’s dual-band optical detector provides rapid flame detection in engine compartments and other high-hazard vehicle zones. Its sensors monitor two wavelengths within the infrared spectrum, combining fast response with improved immunity to common false-alarm sources.
Detectors can be aimed toward individual components or arranged to protect a larger volume. When the detector recognizes a qualifying flame signature, it sends an alarm to the Troman controller, where the event can initiate operator warnings, emergency outputs, and suppression protocols.
Troman’s dual-band optical flame detector uses two infrared wavelengths to detect flames rapidly in bus engine compartments and other high-risk vehicle areas while reducing false alarms.
Fast response where fire can escalate quickly
Direct the sensor toward the components that matter most.
Turbochargers, fuel-system components, hydraulic systems, and hot engine surfaces can create environments where a small ignition event grows quickly. Optical detection provides a direct line-of-sight method for recognizing flame in these zones.
Multiple detectors can be connected on a monitored channel to cover the geometry of a compartment and communicate with Troman controllers.

Continuous line supervision for Troman detector circuits
The Troman end-of-line device completes a detector channel and provides the resistance required for continuous circuit supervision. When the device or part of the circuit is disconnected, the controller recognizes the open circuit and reports a fault.
Installed after the final detector on a channel, the compact device supports optical, gas, and linear detection circuits using compatible Weather-Pack connections. It also helps technicians isolate a fault to a specific channel during diagnosis.
The Troman end-of-line device continuously supervises compatible fire and gas detection channels and creates an immediate fault condition if the monitored circuit is opened.
A small component with an important job
System availability depends on knowing when the circuit changes.
A detector cannot provide protection if the wiring path is incomplete and no one knows it. End-of-line supervision helps distinguish an intact monitored channel from one affected by a loose connection, removed component, or damaged cable.
