Data sheet SEM-SAFE® high-pressure water mist nozzle installation kit SEM-SAFE® high-pressure water mist system SEM-SAFE® is a high-pressure water mist fire fighting system that uses micro-droplets released through the nozzle into protected areas. Water is discharged in a form that ensures fire suppression, control or extinguish. When water is forced through nozzles at high-pressure, a super-fine mist is formed that has a two-fold extinguishing effect. As well as cooling the fire it simultaneously starves the fire of oxygen. The cooling effect also lowers the likelihood of re-ignition. A SEM-SAFE® system comprises several SEM-SAFE® high-pressure water mist nozzles connected by stainless steel piping to a modular SEM-SAFE® high-pressure pump unit. Stainless steel SEM-SAFE® high-pressure water mist section valves are supplied with the SEM-SAFE® system in order to separate the individual fire sections. The SEM-SAFE® pump unit can feed either automatic frangible glass bulb nozzles or open nozzles in `wet’, `pre-action’ or `deluge/dry’ applications. General description of SEM-SAFE® high-pressure water mist nozzle installation kit The SEM-SAFE® high-pressure water mist nozzle can be installed using a dedicated nozzle installation kit. The SEM-SAFE® nozzle installation kit has been developed to fit the SEM-SAFE® high-pressure water mist nozzle and is compatible with any kind of installation. The solution has been developed to facilitate the work of the installer. With the SEM-SAFE® nozzle installation kit the nozzle can be installed last, thus increasing work flexibility for the installer. In addition, the pressure testing can be done before the nozzle is finally installed in the ceilling. For increased simplicity, the SEM-SAFE® nozzle installation kit is suitable for drop-hose installation and fixed piping. The SEM-SAFE® nozzle installation kit has an aesthetically designed cover plate that, with the help of magnets, securely “clicks” to cover the nozzle. With this installation solution, any maintenance and inspection as well as ceiling changes can be done without interfering with the high-pressure water mist nozzle and system. This means that significant time and cost in installation and maintenance can be saved. 901-90-00029 www.semsafe.danfoss.com
