SIGA-CT1

The Edwards SIGA-CT1 is an intelligent single input module from the Signature Series, designed to interface Class B normally-open dry contact devices like pull stations, heat detectors, or waterflow switches with Signature Loop controllers.
It features configurable "personality codes" downloaded from the loop controller for Alarm, Supervisory, Monitor, or delayed-latching functions, with on-board microprocessor signal analysis and automatic device mapping for enhanced system diagnostics.
