The NS6 and NS4 Series is designed specifically for use with Conventional Models SIJ-24 Ionization Smoke Detector, SLR-24 Photoelectric Smoke Detector, SLR- 24H Photoelectric with Heat Smoke Detector, SLR-835 Photoelectric Smoke Detector, SLR-835H Photoelectric Smoke Detector with heat, or DCD-135/190 Fixed Temperature/Rate-of-Rise Heat Detector. The base is an electronics free 6" base featuring a plastic tamper-lock lug. Each base is equipped with a resistor. The NS4 base is a 4" version of the NS6 base.
Models HSC-224R, HSC-220R and HSC-221R are designed specifically for use with the Conventional Models SIJ-24, SLR-24V, SLR-24H, SLR-835, SLR-835H or DCD-135/190. The HSC-(X)R series is a 5" base with two sets of Form "C" relay contacts.
Models HS-224R, HSC-220R and HSC-221R are also approved for use with the previous Conventional Models SIH-24F, SLK-24F, SLK-24FH and the DFE 135/190.The HSC-4R is designed specifically for 24 volt 4 wire applications using Conventional Models SIJ-24, SLR- 24V, SLR-24H, SLR-835, SLR-835H or DCD-135/190.
The 6" diameter base is current limited. Relay contact place a direct short occurs across the loop when the detector is actuated. Model HSC-4R is also approved for use with previous Conventional Models SIH-24F, SLK-24F, SLK-24FH and DFE 135/190.
The HSC-L Base Series is designed specifically for use with the Fixed Temperature Heat Detector 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.
