Edwards EST SIGA-AB4GT CO Compatible Sounder Base

The Edwards EST SIGA-AB4GT is a CO-compatible sounder base for Signature Series detectors that adds local audible output at the device. It supports temporal signaling and, when used with a temporal pattern generator, can separate Fire and CO tones. It may operate as a local alarm with its host detector or as part of a synchronized group under panel control. Key Specifications: Type: Detector sounder base for Signature Series heads Output/Tone: Temporal signaling for Fire and CO when used with a temporal pattern generator Power: 16 to 33 VDC riser input Operation: Follows host detector alarm or group activation via system programming; supports synchronization on compatible systems Mounting: Flush to standard North American and European boxes; optional surface box available Operating Range: 32 to 120 °F; 0 to 93 percent RH, non-condensing Notes: Use with SIGA-TCDR for Fire and CO tone separation Compatible Detectors: SIGA-OSD – Photoelectric smoke detector SIGA-OSHD – Optical smoke and heat multisensor SIGA-OSCD – Optical smoke and CO multisensor SIGA-OSHCD – Optical smoke, heat, and CO multisensor Other Signature Series smoke and heat heads Related Models & Accessories: SIGA-TCDR – Temporal pattern generator for Fire and CO tone separation SIGA-AB4G – Standard audible sounder base SIGA-AB4G-LF – 520 Hz low-frequency sounder base AB4G-SB – Surface-mount box for sounder base System Compatibility: Signature Series control panels using a Signature loop controller.
