    FDC and Exterior Alarm

    I don't believe it is required. A.6.9.3.1 Audible alarms are normally located on the outside of the building. Listed electric gongs, bells, horns, or sirens inside the building, or a combination of such used inside and outside, are sometimes advisable. Outside alarms can be omitted where the...

    Domes

    I've only come across domes in the residential systems I’ve designed, but I believe we use concealed pendents near the top of the dome. If there is a chance that the pipe may freeze, is there a way to make that area a dry pipe system?

    Is learning Autosprink a waste of time?

    I went through the fire protection program at Seneca college and took both HydraCAD and AutoSprink. While I found that AutoSprink worked best for me.

    Finding min psi or gpm

    It's an existing system, they want to use it to store tires in without changing the sprinklers in the area

    Finding min psi or gpm

    I am working on a project that requires the hydraulic calculation to have a 0.39/2600 density. I'm using HASS as my calc program and I can not input the density into the program. I need to get the minimum allowable end head condition in either psi or gpm. Heads are space 10x10 and are 5.6 k-factor.
