™ Model FS24X Fire and Flame Detectors INSTALLATION GUIDE and OPERATING MANUAL If the application for the Detector requires different settings, refer to Section 3.2 for detailed descriptions. Before applying 24 VDC power to the Detector, make sure 1. Wire connections are correct (Section 2.3). Each wire must be stripped properly to the correct length, loose wire strands must be removed and each wire must be securely and firmly screwed clockwise in the connector.
Additionally, do not use these Test Lamps to activate other Fire Sentry Detectors (nor any other conventional fire and flame detectors). Do not use other Fire Sentry Test Lamps or non- Fire Sentry Test Lamps to test the FSX Detectors.

700 nanometers to 7000 nanometers (0.7 to 7.0 microns). Fire Sentry’s FS24X Fire Detectors utilize a NearBand IR™ portion of the spectrum from approximately 0.7 to 1.1 microns and a WideBand IR portion from approximately 1.1 to 7.0 microns. This allows the FS24X Detectors to sense over 80% of the total radiant “Blackbody Energy”...

INSTALLATION GUIDE and OPERATING MANUAL LED Status Indicators The Model FS24X Detector uses three (3) separate, bright LED’s to indicate the Detector’s status. The Blue LED blinks (flashes) once every ten (10) seconds to indicate a Normal, safe operational condition (i.e.
Dirty Window Lens (Yellow LED flashes, the Yellow LED is ON [solid] for all other Faults). Maintenance After the FS24X Detector is installed and commissioned, there is little maintenance required. However, a complete “end-to-end” test of the entire fire detection system should be performed periodically depending on the application.

For calibrated testing, in compliance with NFPA 72 Codes for flame detectors, as manufacturers of the FSX product line, our calibrated testing using our FT-2055X Test Lamp is as follows. If the FS24X set at Highest Sensitivity alarms to a fully charged FT-2055X Test Lamp at a distance between 1 and 25 feet, then the FS24X is in normal operating condition.
