    Entry number 263092

    keyword=tech/ elevated VESDA

    I made a precautionary entry to the Hall due to elevated reading from the VESDA system On entry we noticed a fairly strong ozone smell but no smoke of any kind by smell or visually. The AHU has hit the alert set point and has been isolated and the 2 other open bay sensors are close to the alert set points but have not been isolated so as to give us an indicator if the level continues to raise. While I was in the Hall I checked the dump compressor and the Moeller power supplies and ruled them out as the cause.
