FST-851. Intelligent thermistor sensing circuit for fast response. Designed to provide open area
protection with 50 foot spacing capability. A fixed temperature sensor with 135°F fixed
temperature alarm. FlashScan capable. The FST-851R incorporates a thermal rate of rise of 15°F
(9.4°C). FlashScan capable. The FST-851H is a high temperature sensor with 190°F fixed
temperature alarm.
FSI-751. Analog, addressable, low profile intelligent smoke detector that incorporates an
ionization sensing chamber. Designed to provide open area protection.
FSP-751. Same as FSI-751, but uses a photoelectric sensing chamber. The FSP-751T adds
thermal sensors that will alarm at a fixed temperature of 135°F (57°C). Designed to provide open
area protection.
FST-751. Intelligent thermistor sensing circuit for fast response. Designed to provide open area
protection with 50 foot (15.24 m) spacing capability. The FST-751R incorporates a thermal rate of
rise of 15°F (9.4°C).
FSD-751P. Photoelectric Duct Detector. The FSD-751RP includes an alarm relay. The FSD-
751PL and FSD-751RPL are low-flow detectors.
HPX-751 (HARSH™). A special smoke detector that provides early warning smoke detection in
hostile environments where traditional smoke detectors are not practical. CLIP mode only.
FSH-751 (HARSH™). A special smoke detector that provides early warning smoke detection in
hostile environments where traditional smoke detectors are not practical. FlashScan capable.
IPX-751. A microprocessor-based intelligent smoke detector that uses a combination of
photoelectric, ionization, and thermal sensing technologies. CLIP mode only.
FAPT-751Acclimate Plus™ is a Combination Photoelectric/Heat Detector. This intelligent,
addressable, multi-sensing, low-profile detector can automatically adjust its sensitivity. It uses a
combination of photoelectric and thermal sensing technologies that are designed to increase
immunity to false alarms.
LPX-751. Early detection laser detector, similar to the FSL-751 VIEW®, but limited to CLIP
mode operation only.
FSL-751 VIEW® Low Profile Laser Detector. An advanced intelligent photoelectric detector
that uses a laser diode, special optics, and signal processing to obtain extremely high sensitivity.
FlashScan capable.

Accessories
RA400Z. A Remote Single LED Annunciator that can be wired directly off of an addressable
detector for annunciation of that detector's alarm status.
2.6 Addressable Modules
Control Modules and Monitor Modules provide an interface between the control panel and
conventional notification and initiating devices. Each module can be set to respond to an address
