Aspirating Smoke Detection
combined
with Nitrogen Gas
Fire Suppression
By detecting smoke, the first sign of a fire, the innovative CNF series of ExxFire protects your systems against fire through early detection and suppression, preventing large damage to your hardware.
EN54 certified by CNPP aspirating fire detection combined with non-pressurized nitrogen fire suppression.
Operating Principle
With the help of an active suction system (3-optical sensors detection module with integrated aspiration system), which can be placed close to the source, starting fires within closed cabinets and objects are quickly detected and subsequently extinguished with non-pressurized stored nitrogen.
The resulting smoke of an incipient fire is detected at a very early stage by the 3 optical smoke detectors, 2 of which will go into alarm before the "Alarm" signal is displayed. Immediately after this "alarm message", the system releases an alarm sound and the Cool Gas Generator (CGG) will then be activated extinguishing the incipient fire.
The nitrogen is converted inside the cooling gas generator from solid into a gas form by our unique and patented solution. The outflow of the gas into the protected volume takes place at a very low pressure (3-5 bar) and ambient temperature. This innovative process prevents from any pressure increase and temperature change within the protected volume.
About CNF systems
The 3-integrated optical sensors are the most sensitive smoke detectors in the market. Our Votexx Software combines the reading of each detector and optimize the results to prevent false alarms. An electrical fan samples continuously the air in the protected volume, providing fast smoke detection.
Furthermore, ExxFire systems of the CNF-series are provided with a Flexible User Interface which shows the complete status of the system, fault codes, mute and disable. The User Interface can be placed on 3 different positions on the system to guarantee optimal access to it.
