The NS6 and NS4 series bases are designed specifically for use with Hochiki’s conventional models:
Photoelectric smoke detectors: SOC-24V, SOC-24VN, SLR-24V, SLV-24, SLV-24N, SLV-24V, SLR-835, SLR-24H
Photoelectric with heat smoke detector: SLR-835H
Fixed temperature/rate-of-rise heat detector: DCD-135/190
The NS6 base is an electronics free 6" base featuring a plastic tam-per-lock lug. Each base is equipped with a resistor. Please refer to the chart (left) for additional specifications. The NS4 base is a 4" version of the NS6 base.
Models HSC-224R, HSC-220R and the HSC-221R are designed specifically for use with the Hochiki conventional models SOC-24V, SOC-24VN, SLR-24H, SLR-24V, SLV-24, SLV-24N, SLV-24V, SLR-835, SLR-835H, DCD-135/190. The HSC-(X)R series is a 6" base with two sets of Form "C" relay contacts.
Models HSC-224R, HSC-220R and the HSC-221R are also approved for use with Hochiki’s previous conventional model DFE 135/190.
The HSC-4R is designed specifically for 24 volt 4 wire applications using Hochiki conventional models SOC-24V, SOC-24VN, SLR-24H, SLR-24V, SLV-24, SLV-24N, SLV-24V, SLR-835, SLR-835H or DCD-135/190. The 6" diameter base is current limited. Relay contact place a direct short circuit across the loop when the detector is actu-ated.
Model HSC-4R is also approved for use with Hochiki’s previous conventional model DFE 135/190.
The HSC-L base series are designed specifically for use with the Hochiki fixed temperature heat detectors (models DFE-135/190).
The HSC-L series is a 6" base featuring a current limiting resistor, latching annunciator output and a latching circuit so the alarm LED will remain lit until the control panel has been reset.
Bases are available in bone or white to match the detector. Bone (off-white) is the standard color for detectors and bases for most applica-tions.

Resistor shown is for example only. Not all annunciators have in line resistance.
Annunciation device must be current limited to 20 mA @ 24VDC
Maximum. Not limiting current could result in damage to the
detector or cause a no alarm condition.
