The UL Solutions Fire Alarm Systems Certification Program (ULS FASCP) has existed for decades. It aims to improve the reliability of commercial fire alarms through a community’s adoption of more stringent fire alarm maintenance, service, and record-keeping processes. However, as the program’s implementation occurs locally, it is difficult to understand its outcomes fully.
In 2020, UL Solutions approached the International Public Safety Data Institute to determine if the use of the ULS FASCP impacts commercial fire alarm occurrences. That engagement led to a pilot study comparing two cities, which indicated a lower commercial
fire alarm rate in the community that utilized the UL FASCP.
This report (published June 2025) describes the process, methodology, and result as IPSDI and ULS continued
comparing communities that implemented the ULS FASCP versus those that did not.
