When are standard response sprinkler heads a better choice than quick or fast response heads (5mm vs. 3mm bulb)?
Are there applications where it would be preferable to have a slower response time?
As far as I know, quick and standard response heads cost the same, come with the same k-factors, and the same temperature ratings.
Why would the slower one be chosen? When would you choose a Tyco TY-B instead of a TY-FRB?
