Kidde GSA-CRR

The Kidde GSA-CRR is a polarity reversal relay module that reverses 24VDC riser polarity to activate all sounder bases on a fire alarm loop. When integrated with a Kidde Signature Series loop controller, this module provides a Form C relay contact rated for 2 Amps @ 24Vdc pilot duty, enabling coordinated alarm signaling across distributed audio alerting devices.
