Overview
▪ The module is used to monitor the opening and closing states of the fire door, and can report states of the fire door to the fire door monitor.
▪ With a built-in high-performance microprocessor, the module accurately distinguishes the door states, including closed, left-door open, and right-door open.
▪ HW & SW-based filtering improves the anti-jamming capability of the module.
▪ Low-power two-bus connection is used.
▪ Electronic coding, simple and convenient.
▪ Fire door: Both left and right doors are monitored.
