Introducing the GSA-REL
Description
The GSA-REL Releasing Module (Figure 1) is a Signature Series component

Figure 1: GSA-REL Releasing Module
The GSA-REL controls operations for deluge, preaction, and automatic fire
extinguishing systems. The release circuits control the release of gas and other
fire suppression agents by controlling the release solenoids. The release circuits
operate in unison and cannot be controlled separately.
Prerelease circuit 1 supports audible notification appliances that sound alert,
prerelease, and release signals. Prerelease circuit 2 supports visual notification
appliances.
