SEM-SAFE® high-pressure water mist system The building was fitted with a SEM-SAFE® high-pressure water mist fire fighting system from Danfoss. The installation work commenced in December 2010 and was completed in September 2011. The installation was timed to coincide with the main construction work schedule. The system consists of the SEM-SAFE® electric pump unit, 3,800 m pipes and 722 nozzle heads. Approving authority The system design was approved by Alarm Control Alco Oy Ab, one of the three inspection companies accredited by the Finnish Safety Technology Authority. The design was then inspected by the Pirkanmaa Provincial Fire Department. The final installation was tested and inspected by Alarm Control Alco Oy Ab. The fire test criteria were not needed due to a prior acceptance of the system’s components. The main contractor and the commissioner of the building explain: • Water mist was chosen over conventional sprinklers due to: - Minimized water damage upon system activation - Aesthetic appearance compared to a sprinkler system • The investment cost was lower than anticipated, and viewed to be within an acceptable range compared to a conventional sprinkler system. • The same pump unit also suplies water to the neighboring 6-storey senior care service home, also fitted with a SEM-SAFE® high-pressure water mist system. SEM-SAFE® nozzles: • Architecturally attractive • Aesthetic design • Short installation time • Efficient cooling The SEM-SAFE® system for high-rise buildings offers several advantages: • No need to place a large resorvoir • No need for large water supply resorvoir • No risk of pressure loss. ® Danfoss Fire Safety A/S · Middelfartvej 9 · DK-5000 Odense · Denmark Tel. +45 7488 7800 · E-mail firesafety@danfoss.com · www.semsafe.danfoss.com Danfoss Fire Safety A/S can accept no responsibility for possible errors in catalogues, brochures and other printed material.
