SIGA-AB4G

The Edwards SIGA-AB4G is an audible sounder base for Signature Series detectors, adding localized alarm signaling capability directly at the detector location for enhanced life safety notification.
It features field-selectable high/low dB output and temporal/steady tone patterns via jumpers, operating either independently with its host detector or synchronized as a group under panel control for NFPA 72 compliance.
