Overview
Signals received from local temperature sensors or remotely from a safety management system triggers an automatic fire door (AFD) to close – likely via a spring-loaded mechanism – to prevent the spread of smoke and fire. The opening of an AFD is controlled by a motor, and door opening and closing and high temperatures are detected by sensors. In addition to these mechanisms the controller is required to activate audible and visual alarms.
Renesas' range of 8/16-bit microcontrollers has functions and interfaces suitable for a variety of application requirements.
