Refer to the Technical Bulletin 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:
FCP-350-P Multi-criteria Smoke Detector (Compatibility ID HD-3)
FCP-350-PTH Multi-criteria Smoke and Heat Detector (Compatibility ID HD-3)
FCH-350-135/FCH-350-190 Fixed Temperature and Rate of Rise Detector (Compatibility ID HD-3)
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.
