SIGA-AB4G-LF

The Edwards SIGA-AB4G-LF is a low-frequency audible sounder base for Signature Series detectors, providing 520 Hz signaling specifically designed for enhanced audibility in sleeping areas and compliance with NFPA 72 sleeping room requirements.
It adds localized low-frequency alarm capability directly at the detector location, operating independently with its host detector or synchronized as a group, with field-selectable volume settings and temporal pattern support when paired with a SIGA-TCDR temporal generator.
