• GE FHSD720C, GE Security FHSD700C Series Product Guide 1 Introduction Welcome to the GE Security FHSD700C Series Product Guide. This document is written to provide you with information on technical specifications, cabling, and how to install, configure and operate these detectors. FHSD700C Series detectors are aspirating smoke detectors that provide early warning of fire by analyzing air drawn through an air sampling pipe network. A highly sensitive detector chamber is able to detect smoke at very low concentrations. Embedded and PC software enable the configuration of a wide range of user defined parameter

• GE FHSD720C, FHSD700C Series Product Guide GE Security 2 Principle of Operation Air samples are drawn through the pipe network from the protected area through wide or small bore pipe systems. Wide bore tubes generally have sampling holes drilled at intervals within the protected area while small bore tubes normally sample air at their end points. The aspirator draws air from the pipe network into the detector inlets where the samples are combined, filtered, and directed to the laser detection chamber. Systems incorporating a rotary valve have an Overall position which draws air equally from all sectors. In contrast, the FHSD721C / FHSD721DC
