Product Overview

The HSC-4R is a 6-inch conventional detector base designed for 24V 4-wire fire alarm systems using Hochiki conventional detectors, including models SLR-24H, SLR-24V, SLV-24 series, SLR-835 series, DCD-135/190, and legacy DFE 135/190. The base features current-limited circuitry and a relay contact that places a direct short circuit across the loop when the detector is actuated, ensuring reliable alarm signaling and system protection.
