To Glyn Balkwill: A colleague has passed along to me an inquiry you had on automatic sprinkler systems, as well as several responses to your inquiry. As a fire protection engineer with extensive museum related experience (I've headed the Smithsonian's fire protection engineering division for over 15 years), I would be happy to answer any and all questions you may have regarding these or other fire systems. My phone number is 202-287-3613, my fax # is 202-287-3243, and my Internet address should be with this note. *************************************** Andy Wilson (202) 287-3613 OEMSFR01@SIVM ***************************************
