DIRECT EXTINTION: Formed by cylinder, valve, fitting clamping FIRELINE detector tube and end of line. The FIRELINE detector tube is used as a detector and a system of agent discharge. The increase of temperature breaks the tube creating a perfect cylindrical hole that serves as diffuser discharging the extinguishing agent directly onto the source of the fire. This system is ideal for enclosed spaces below 1 m3. INDIRECT EXTINTION: Composed of cylinder, valve, fitting, tube FIRELINE detector, end of line, diffusers and manual shooting. The FIRELINE detector tube is used as a detector only, firing valve and discharging extinguishing agent through the diffuser. The temperature rise breaks the tube, actuating the valve by pressure difference, discharging the extinguishing agent by diffusers located on the risk. This system is ideal for closed volumes between 1 and 5 m3.
