Fire Sprinkler Systems Austin TX. Perhaps one of the biggest benefits of a home fire sprinkler system involves insurance premiums. More specifically, these types of discounts can range from 5% to 45%; however, it should be noted that this depends on the overall design of the sprinklers, as well as the areas that are protected. Higher discounts will more than likely be available as a result of the combination of sprinkler protection and other features such as system monitoring and smoke detection. Other benefits include decreased loss of life and overall peace of mind. These systems are also important when it comes to the construction of new homes as well, as they literally protect the structure on a 24/7 basis.
