Installation Practices
For installations in a Hazardous Classified Area, consult the National Electric Code Handbook, Articles 500
through 517 for the proper installation practices. For locations outside of the United States, observe local
and/or regional regulations.
Model FS24X911-24-5 detectors must be connected to control panels meeting the requirements of either
NFPA 71 or the local authority having jurisdiction.
IMPORTANT: The Detector's metal conduit plug by itself cannot make a weather-tight seal. Metal-to-metal
does NOT provide protection against the ingress of moisture. It is necessary to obtain an approved material to
apply to the threads in order to maintain the "weatherproof" integrity and satisfy local/regional regulations.
Before completing the installation, check that the Detector is configured correctly for the specific
application. The FSX Detectors Factory Default Settings are:
Alarm Relay Outputs are Non-Latching and Normally De-Energized
Detector Range / Sensitivity is Medium (2)
Auxiliary Relay Verify Time is set to 5 seconds
End of Line Resistor is Disabled
Fault Relay Output is Normally Energized
Communication is set to FireBus
Factory Use Only
Digital Communication Address is set to 127
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.
2. If using conduit, ensure a proper conduit seal, (appropriate for the area classification), has been
installed and all measures to prevent moisture ingress have been taken.
3.
Consult the manufacturer for dimensional information on the flameproof joint specifications.
4. The FSX Detector is securely mounted and has an unobstructed view of the area of coverage
(Section 2.1).
5. The Detector window is unobstructed and clean.
6. To ensure optimum performance, shield the detector face from intense bright light sources when first
energized.
The Detector is now ready for Power-Up. on Power-Up, the Fault Relay will change status if the Factory
Default Setting is used (Section 3.2).
