The system uses fuse links for mounting the curtains. Fuse links work on the same technology as fire sprinklers. Sprinklers are held in the closed position by a fusible alloy wire. When the fire reaches a predetermined temperature, the alloy melts and opens the valve for the sprinkler. By using fuse links to attach the mounting hardware of the curtains and strip doors in the data center, Simplex is able to ensure that the curtains will fall away and the sprinklers will be fully operational. <br><br>Simplex has specially formulated vinyls which meet the standards of the California (United States) State Fire Marshall, the requirements of American Society for Testing and Materials (ASTM), and the National Fire Protection Association (NFPA). <br><br>Regarding the aesthetics of these systems, Simplex has also installed several systems using hard wall partitions. For data centers that are in high visibility locations and receive a good deal of VIP visitors, these panels are an ideal solution. They do require additional add-ons so that the fire sprinkler system will meet approval. <br><br>Also keep in mind, at least in the United States, that many electrical utilities provide a rebate for installing these systems. When you ad the rebate from Pacific Gas & Electric (PG&E), the NetApp system paid for itself in about five weeks.

To get around this we have developed an active airflow system which effectively gets the same results as containment but is done by an air curtain.<br><br><a href="http://www.adaptivcool.com" rel="nofollow">www.adaptivcool.com</a>GrisoLM1Mon, 08 Sep 2008 15:16:22 -0000
