Product Overview

A Modular Fire Suppression System For Vehicles And EVs

The Sentinel is an intelligent vehicle fire suppression system built to protect engine bays, passenger compartments, EV battery enclosures, and critical vehicle systems. Using advanced IR flame detection and heat monitoring, it watches multiple zones continuously and responds automatically the moment a fire threat is detected.

Precision nozzles target the source of the fire, while GSM/4G connectivity delivers real-time alerts by mobile app, SMS, and email. Built with rugged IP67-rated electronics, The Sentinel suits passenger vehicles, EVs, public transport, commercial fleets, heavy machinery, and motorsport, delivering reliable 24/7 protection in demanding environments.

Key Capabilities

Everything The Sentinel Delivers

Engineered for the vehicles and machines that face the highest fire risk, in the toughest operating conditions.

IR Flame + Heat Detection

A dual-sensor approach pairs infrared flame detection with rate-of-rise temperature monitoring in every zone. Fast, accurate, and reliable.

Multi-Zone Protection

Up to four modules cover the engine bay, cabin, and EV battery zones independently. Normal Mode or Race Mode activation gives you precise control.

120° Precision Nozzles

SS316 nozzles with a 120-degree full-cone spray pattern. Sensor field of view is aligned with the spray cones for synchronized detection and suppression.

GSM/4G Connected

Real-time alerts by app, SMS, and email. OTA firmware updates. An API for fleet integration lets you manage multiple vehicles from a single dashboard.

IP67 Electronics

Conformal-coated PCB, automotive-grade connectors, and IP67-rated electronics, engineered to survive vehicle vibration, heat, and moisture.

Refillable Cylinder

An SS316 pressure vessel, refillable with approved water-based fluid. No re-certification is required when the refill procedure is followed, on an annual inspection schedule.

How It Works

From Detection to Response — Automatically

Detect

IR flame and rate-of-rise temperature sensors in each zone monitor continuously for fire threats, from engine bays to EV battery compartments.

Decide

Normal Mode discharges only the triggered zone, extending available fluid. Race Mode discharges all zones simultaneously for maximum response.

Discharge

120-degree full-cone nozzles, fed by braided stainless hoses, deploy suppressant precisely at the fire source across a 1.5 to 2.0m radius in open areas.

Notify

Automatic alerts via app, SMS, and email for fire events, zone discharges, low battery, and system faults. Fleet dashboard updated in real time.

FAQ

Frequently Asked Questions

What is the difference between Normal Mode and Race Mode?

Normal Mode activates only the module in the detected zone, conserving fluid and targeting the specific threat. Race Mode activates all modules simultaneously for maximum immediate suppression, which suits motorsport and high-speed scenarios.

Up to four. Each module runs independently, so a typical build might cover the engine bay, the cabin, and an EV battery compartment, with a fourth zone available for an additional high-risk area.

Yes. An open API lets you feed fire events, zone discharges, and system health into your existing fleet platform, and the dashboard manages multiple vehicles from a single view.

Yes. Race Mode discharges every zone at once, and the system supports dual FIA-style activation alongside the standard dashboard button.

Is the Sentinel compatible with electric vehicles (EVs)?

Yes. The Sentinel is designed to protect EV battery compartments as a dedicated zone, and is engineered for both traditional combustion vehicles and electric or hybrid platforms.

No. The SS316 cylinder is refillable with approved water-based fluid, and no re-certification is required provided the specified refill procedure is followed.

Modules mount at each protected zone using the supplied brackets, connected to the cylinder by 12mm braided stainless hoses in 5m standard lengths, extendable to 10m. Installation should be carried out by a qualified fitter to keep sensor field of view aligned with the nozzle spray cones.

An annual inspection, plus a refill after any discharge. The system reports low battery and fault conditions automatically, so routine health checks happen continuously rather than on a manual schedule.
