For more than 35 years, HRS Systems has prided itself on being a dynamic, fire protection software development company providing fast, accurate, and easy-to-use software for fire protection professionals. Our goal is to provide the best available fire protection software worldwide.

Accuracy of calculations and results are of prime importance, with ease of data entry and attention to overall user experience ranking a close second.

HASS (Hydraulic Analyzer of Sprinkler Systems) was first developed for sprinkler system design and licensed for use by IBM® in 1976 as a marketing tool for the IBM® 5100 computer for use by engineers, sprinkler contractors, and reviewers. HASS has been enhanced continually and updated on an annual basis to maintain state of the art software and NFPA 13 standards compliance for analysis of the water supply adequacy based on any configuration of system piping for industrial, commercial and residential sprinkler systems.

All licensed users of the HASS software suite receive major revisions, year in and year out which often include improvements or new features at no extra charge. Consequently, the investment made in any given year is continually enhanced as updates are received. You are invited to purchase a HASS license and join the thousands who use HASS on a daily basis in over fifty countries worldwide!
