Indirect System (R107 Approved)
The Alliance UNECE R107 Vehicle system utilizes CTX Indirect™ valve technology.
This technology employs the Alliance – Reacton® Detection Tube to automatically detect the fire and actuate the system.
The tubing is installed in and around the fire risk areas within the protected risk. The tubing is pressurised and in communication with the valve which holds it in the closed position.
When a fire occurs, the tubing will burst at the point of highest heat, the pressure loss in this process causes the valve to open. (This pressure loss function can be simulated through the use of a manual actuator).
The result of the valve opening allows the extinguishing agent to be delivered through a network of discharge hoses leading to strategically placed nozzles within the hazard.
