Product Overview

The NS6 Base is a 6-inch, electronics-free detector base designed for dependable performance in conventional fire alarm systems. It features a plastic tamper-lock lug and includes an integrated resistor for proper circuit supervision.

The HSC-220R, HSC-221R, and HSC-224R models are specifically designed for use with Hochiki conventional detectors including SLR-24H, SLR-24V, SLV-24, SLV-24N, SLV-24V, SLR-835, SLR-835H, and DCD-135/190, and are also approved for legacy DFE 135/190 detectors. The HSC-(X)R series offers a 6-inch base configuration with two sets of Form “C” relay contacts, providing added control and signaling flexibility.
