    Shared Alarm Systems

    That just about nails it. Thank you, I have been searching for a while. So, they probably need to run it past their local fire marshall/regulating body, but it seems as though per the wording of NFPA 72 it is acceptable. Thank you for your quick response!

    Shared Alarm Systems

    I do believe that NFPA does say distinct, but that also raises debate as to what 'distinct' means. Is a separate tone or code from the same system distinct...etc... I have also seen the term, clear and identifiable, but that also allows the same debate to ensue. Thank you for your response...

    Shared Alarm Systems

    I am currently doing a review of codes to see if there is any code that would prohibit using the fire alarm horns (With a separate code) to use for Ammonia leak detection alarms. So far what I have seen from ASHRAE/IMC/IFC/NFPA, there is nothing that requires the fire system to have its own...

    Clean Room Sqft/Ton refrigeration

    I think it should be higher because we also have a 25 hp re-circulation fan from which we need to handle a heat load as well.

    Clean Room Sqft/Ton refrigeration

    Thanks guys, There is only a very small heat load from equipment in the room, and the outside air is set at 20% right now. I will do the calcs over again just to make sure I am not missing anything.

    Clean Room Sqft/Ton refrigeration

    Hi all, I have been reading around on this forum for many years, and finally have a question to ask for myself. Really I am just looking for a guideline to make sure I am in the correct ballpark with my numbers. I am designing a new air handling unit for a Pharma facility, and have gotten to...
