Fire Sprinkler Alternatives

[Keely C.]

Working through a messy permitting issue in Los Angeles, CA.  LADBS is requiring installation of a fire sprinkler system.  I plan to submit for a modification.  Does anyone have advice on an alternative Active Fire Protection System that is less expensive but will still satisfy the city in place of sprinklers?  Can anyone explain an alarm system that goes right to the fire station, and the costs involved?  I am also willing to put in fire extinguishers as a Passive system.  Thank you
