Edwards SIGA-IB4

Edwards SIGA-IB4 Isolator Detector Base

The Edwards SIGA-IB4 is a Signature Series detector base with built-in line fault isolator designed for Class A signaling line circuits. This intelligent isolation base prevents circuit loop failure from disabling entire detection zones.

Key Features:

• Fault Isolation: Short circuits cause all isolators to open within 23 ms; sequential closure isolates fault location

• Mounting: 4-inch square boxes, 1-gang boxes, 3½ to 4-inch octagon boxes

• Included Trim: SIGA-TS4 trim skirt included for finished appearance

• Sensor Compatibility: Works with full line of Signature Series sensors

Technical Specifications:

• Operating Range: 32 to 120°F (0 to 49°C), 0 to 93% RH non-condensing

• Wire Size: Accepts 12 to 18 AWG conductors (16-18 AWG preferred)

• Isolation Response: 10 ms intervals starting from nearest loop controller

Certifications:

• UL Listed: Intelligent detector base with fault isolator
