Intelligent, addressable detectors provide analog information to the control panel. This
allows the control panel to continually process this information to determine the status
of each detector (alarm, trouble, maintenance, or normal). Each detector responds to an
address that is set in the detector head using built-in rotary decimal switches. You can
program the sensitivity of each intelligent detector. (Refer to Appendix C in the
AFP-300/AFP-400 Programming Manual for details.)

SDX-751
An Intelligent Photoelectric Smoke Detector provides analog
measurements of the optical smoke level in its chamber to the
control panel. Also available: an SDX-551TH with a 135°
thermostat and a SDX-751 low profile photoelectric detector.
CPX-551/CPX-751 An Intelligent Ionization Smoke Detector measures the level
of combustion products in its chamber using the ionization
principle and reports this measurement to the control panel. A
CPX-751 Low Profile detector is also available.
Refer to Appendix C in the AFP-300/AFP-400 Programming
Manual for details on setting alarm sensitivity.
FDX-551 An Intelligent Thermal Sensor (140°F fixed temperature).
Also available as an FDX-551R which is a combination
135°F fixed and 15°F per minute rate of rise.
RA400Z A Remote Single LED Annunciator that can be wired directly
off of an addressable detector for annunciation of that
detector's alarm status.
DHX-501/DHX-502 Duct Housings for the SDX-551 and CPX-551.
IPX-751 A microprocessor-based intelligent smoke detector that uses a
combination of photoelectric, ionization, and thermal sensing
technologies.
LPX-751 An advanced intelligent photoelectric detector that uses a
laser diode, special optics, and signal processing to obtain
extremely high sensitivity.
