SAFETYCAR Automatic Fire Suppression System User Manual & Installation Guide
Please read this guide carefully before installing or using the product and retain it for future reference.
The flexible yet durable tube of the SAFETYCAR® Automatic Fire Suppression System can be mounted under the bonnet, above the engine or in any other enclosed vehicle space you wish to protect. Installation is simple and usually takes less than 30 minutes in most vehicles.
What Is the SAFETYCAR Automatic Fire Suppression System?
The SAFETYCAR Automatic Fire Suppression System is an automatic fire suppression system designed to provide cost-effective and reliable protection for vehicle engine compartments.
Offering 24/7 fire monitoring and detection, it activates automatically without manual intervention to release a high-performance clean fire extinguishing agent. The system operates without a power supply and can be installed in passenger cars, classic and vintage automobiles, and track cars.
The system features a specially designed tube containing a precise volume of SCL25™ Clean Agent for optimum performance in vehicles. The durable polyamide tube is engineered to provide long-lasting protection within the demanding conditions of vehicle engine bays.
How Does the SAFETYCAR Automatic Fire Suppression System Work?
When a fire occurs, the system’s temperature-sensitive tube bursts at the activation temperature.
The SCL25™ Clean Agent stored inside the tube is released as a fine, pressurised mist to rapidly suppress flames before dispersing as a gas.
SCL25™ Clean Agent is non-conductive, non-corrosive and suitable for use around sensitive vehicle electronics. It leaves no powder or messy residue and is effective against Class A, Class B, Class C and electrical fires.
The system requires no vehicle electrical connection and remains active continuously, including while the vehicle is parked and unattended.
