Local Extinguishing Systems

LES-RACK is a self-contained, fully automatic fire detection and protection system. Designed for direct installation into 19” racks with IP30 or higher, offering an effective solution for servers, telecommunication and control racks/cabinets.

The LES-RACK-M1 unit comes with a fully equipped fire detection, control, evaluation, communication and extinguishing system. Larger-sized server racks and adjacent cabinets can be protected with additional auxiliary LES-RACK-M1.

LES-RACK employs clean gas, flooding the protected space until the fire is completely extinguished. The unit is comprised of metal cylinders filled with agent FK-5-1-12 in accordance with TUPO (the Technical Institute of Fire Protection, Authorization Body 221). The pressureless construction solution also enables air transport. After activation, the device can be refilled with extinguishing agent directly at the installation site.
