Product DescriptionThis addressable input module is designed to integrate conventional initiating devices into an intelligent fire system by providing two supervised input zones that share a single address on the communication loop, allowing efficient expansion without increasing device count. It monitors normally open or normally closed dry contact devices and continually supervises the connected wiring to detect open circuits short circuits or other abnormal conditions. The module operates directly from the signaling line circuit without requiring any auxiliary power and supports both Class A and Class B wiring configurations for maximum flexibility in commercial installations. Its compact structure allows clean placement within a standard electrical box and its intelligent protocol ensures fast reporting precise status updates and stable long term performance within large networked environments. This module is well suited for facilities that require reliable monitoring of waterflow switches pull stations supervisory switches or other contact based devices while maintaining full compliance with modern fire protection system requirements.
