Criticality Accident Alarm System (CAAS) User Experience

I am interested in speaking with professionals who have direct experience using Criticality Accident Alarm Systems (CAAS) manufactured by Pajarito Scientific Corporation (PSC). In particular, I would like to better understand the age and current performance of existing PSC systems, identify operational and maintenance challenges, evaluate overall user satisfaction, and explore future plans, including system upgrades, expansion of existing installations, or the potential consideration of alternative CAAS providers. Ideally, I would like to speak with individuals involved in the operation, maintenance, engineering, or procurement of these systems.
