NS4-100 HOCHIKI

Product Overview

The NS4 is a 4-inch, electronics-free conventional detector base designed for reliable and secure installation in fire alarm systems. It features a plastic tamper-lock lug and comes equipped with a 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 series, SLR-835 series, DCD-135/190, and legacy DFE 135/190 models. The HSC-(X)R series utilizes a 6-inch base design and includes two sets of Form “C” relay contacts for expanded system functionality.
