Edwards SIGA-AB4G-RC

The Edwards SIGA-AB4G is a Signature Series audible sounder base that adds a local sounder function to any Signature Series single-function smoke detector, mounting into a standard 2-1/8" deep, 4" square North American electrical box (or the optional AB4G-SB surface box). Jumpers on the base select steady or temporal tone and high or low dB output, and the base can sound independently with its own detector or be grouped with other bases on the same circuit for a synchronized zone or system alarm using a SIGA-CRR polarity-reversing module and a G1M-RM signal master.

Key Features

• Adds local audible sounder output to any Signature Series single-function smoke detector
• Field-selectable temporal or steady tone via jumper (default: temporal)
• Field-selectable high or low dB output via jumper (default: high)
• Can operate as an independent local alarm or as part of a synchronized group/zone alarm
• Uses the same address and programming label as the detector it supports

Technical Specifications

• Power: 24 Vdc in/out, looped to the next base or listed EOL relay
• Data: Data in/out terminals for the Signature Series data loop
• Mounting: Flush to a 2-1/8" deep, 4" square North American electrical box, 4x4 octagonal concrete ring, or 100mm European box; or surface-mount to the optional AB4G-SB box (6.8" dia. x 1.8" deep)
• Group synchronization: SIGA-CRR polarity-reversing module + G1M-RM signal master (both optional)
• Not for use with combination smoke/CO detectors in Fire-plus-CO mode (use SIGA-AB4GT instead)

Certifications

• UL 268 and UL 464 listed as a smoke detector accessory / audible signal appliance
