It is a three floors level area, what are the minimum requirements to convert such wet system to a double interlock pre-action system? ________________________________________ From: [email protected] [[email protected]] On Behalf Of Reed Roisum [[email protected]] Sent: Friday, September 04, 2009 3:46 PM To: '[email protected]' Subject: RE: Fire Sprinker System Changes in Vis Lab
Jaber, What kind of advisement are you looking for? The plan for protecting this space with NOVEC 1230 and using VESDA early warning detection sounds like the way to go. Are you questioning removing the sprinkler system? You will most likely need AHJ approval to install only the clean agent system in lieu of sprinklers (although this isn't IBC world is it?). You might want to advise the owner to consider having a sprinkler system 'back up'. Sounds like a pre-action system would be warranted with the level of fear it sounds like they have. You can also try to dispel some of the unfounded fears they probably have regarding accidental discharges, but don't expect them to be ok with a wet system remaining in this space. There are a number of other considerations to be made...such as sealing of the room. Does it have a drop ceiling? We can discuss more once I know what you are after. Reed A.

Have a look at his draft letter highlighted bellow and advise us accordingly. Thanks in advance. ------------------------------------------------------------------------------------------------- Changes to sprinkler system in Vislab Area of building one. The current sprinkler arrangement in the vislab section of building puts our visualization equipment at significant risk. The water based system if it goes off could easily ruin millions of dollars of equipment in a very short period of time. Including all Sony projectors that drive the CAVE and MPR areas. For this reason it is imperative that we make changes in these spaces to the current fire system. Visualization laboratory a plan for corrective action has been prepared and is recommended as the best course of action. First the building fire detection system should be extended to the Vis lab Data Center, Recording Room, DS1, DS2/3, CAVE and MPR Projection spaces. This will ensure timely notification of any emergency to the response team. Second the current sprinkler system in the above areas should be closed and drained of water to ensure no accidents can cause loss of equipment through water damage. Additional Fire Extinguishers should be placed in these areas as well. Third a permanent solution utilizing VESDA detection system and NOVEC fire suppression system should be installed in all of these areas. The installation should be carried out in such a way to minimize laboratory downtime to a maximum of a single week. We believe this can be done by the careful removal of the most delicate equipment from the lab space, covering the remainder in protective plastic and having NOVEC piping installed and configured after the delicate equipment has been removed. A similar adjustment must be made to the two lecture hall projection rooms containing Sony 4K projectors. We believe that these changes would be in the best interest of a long term protection of its investment in its visualization equipment.
