Edwards Systems Technology

Edwards Systems Technology (EST) is a global leader in fire detection, emergency communications, and life safety systems. Founded in 1872 and currently a brand under Carrier Global Corporation, the company specializes in integrated building technologies, including the EST3 and EST4 fire control platforms. While primarily an industrial safety firm, EST is a significant player in the healthcare technology sector through its specialized nurse call systems and hospital-grade emergency notification platforms. Its solutions are widely deployed in clinical environments to ensure patient safety and streamline staff communication. The company is distinct from Edwards Lifesciences, as EST focuses on building infrastructure rather than cardiovascular medical devices.
