Addressable Devices
Addressable devices include intelligent detectors, monitor modules, control modules and manual pull 
stations.
Intelligent Detectors
Intelligent addressable detectors provide analog information to the control panel on a Signaling Line 
Circuit (SLC). This allows the control panel to continually process this information to determine the 
status (alarm, trouble, maintenance or normal) of each detector. Each detector responds to an SLC 
address that is manually set in the detector head using built-in rotary decimal switches. The detectors 
send a unique Type Code to aid the automatic programming feature in the control panel.
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. Designed to provide open area protection.
FST-751 - Intelligent thermistor sensing circuit for fast response. Designed to provide open area 
protection with 50 foot spacing capability. The FST-751R incorporates a thermal rate of rise of 15°F 
(9.4°C).
FSD-751 - Photoelectric Duct Detector. The FSD-751RP includes an alarm relay.
HPX-751 - A special smoke detector that provides early warning smoke detection in hostile 
environments where traditional smoke detectors are not practical.
