SIGA-REL

The Edwards SIGA-REL is an intelligent analog addressable releasing module designed for controlling sprinkler, pre-action, deluge systems, and clean agent suppression systems like CO2, Halon, or foam release.
It provides field-configurable options for release timing, abort functions, and service disconnects with manual switches, integrating directly with Signature Loop controllers without requiring separate releasing panels.
