NOTES:
Alarm current for 2-wire operation applies to the FACP Initiating Device Circuit and detector.
Alarm current for 4-wire operation applies to the Auxilliary Power Supply and detector.
NS4-100 and NS6-100 must be current limited by the FACP
Standard base is ivory color, W suffix indicates white color
Refer to the Technical Bulletin HA-06-434 issued 07/21 (accessible at www.Hochiki.com) for the following UL listed
compatible detectors. Connect these detectors only to a listed-compatible control panel. Refer to the control panel
installation manual for additional instructions. Smoke detectors are not to be used with detector guards unless the
combination has been evaluated and found suitable for that purpose:
SOC-24V/SOC-24VN/SOC-24VW Smoke Detector (Compatibility ID HD3)
SOE-24V/SOE-24V (WHT) Multi-criteria Smoke Detector (Compatibility ID HD3)
SOE-24H/SOE-24H (WHT) Multi-criteria Smoke and Heat Detector (Compatibility ID HD3)
DCD-135/DCD-135W Fixed Temperature and Rate of Rise Detector (Compatibility ID HD3)
DCD-190/DCD-190W Fixed Temperature and Rate of Rise Detector (Compatibility ID HD3)
DSC-EA/DSC-EAW Rate of Rise Dry Contact Heat Detector
DFE-135/DFE-135W/DFE-135C Fixed Temperature Dry Contact Heat Detector
DFE-190/DFE-190W/DFE-190C Fixed Temperature Dry Contact Heat Detector
Detectors must be installed and maintained in accordance with applicable NFPA standards, local codes and any authority
having jurisdiction. Refer to NFPA 72 "National Fire Alarm and Signaling Code" for installation guidelines and testing
procedures. Smoke detectors should be tested in accordance with NFPA 72, section on "Inspection, Testing and
Maintenance".
Seal conduit openings in the electrical box with 3M Weatherban #606 nonflammable sealing compound (or equivalent)
to reduce the stack effect. Attach the detector to the base by turning the detector clockwise until it stops.
