Emergency Control Functions in Buildings

The video tutorial explains emergency control functions, which enhance building life safety by allowing fire alarm systems to interact with other building systems. It covers common types of emergency control functions, such as elevator control, HVAC shutdown, and door release, and explains how these functions are implemented through interfaces like relays. The tutorial also discusses the importance of proper wiring and the placement of interface devices to ensure fail-safe operation.
