The design of laboratory alarm systems involves creating a system that can detect and alert in case of emergencies, such as fires, chemical spills, or gas leaks. It typically includes sensors, a control unit, and an alert mechanism. Sensors monitor conditions and send signals to the control unit, which processes the information and triggers the alert if necessary. Alarm systems can be integrated with building automation systems for centralized monitoring and control. Design considerations include reliability, ease of maintenance, and compliance with safety standards.
