The Edwards EST SIGA-SB is the standard mounting base for Signature Series intelligent detectors. It connects compatible Signature Series detectors to the signaling line circuit (SLC) and provides room-side accessible wiring terminals after installation.

The SIGA-SB supports connection to a SIGA-LED remote alarm indicator and is designed for use with the Signature Loop Controller. It mounts to a variety of North American and European electrical boxes, supporting flexible installation scenarios in commercial fire alarm systems.

The base is constructed of high-impact engineering polymer and is suitable for environments up to 120°F (49°C) and 93% relative humidity (non-condensing).
