ATTENTION
:
FSX Power-Up
– After the application of 24 VDC input power or resetting the Detector,
wait a mimimum of (thirty) 30 seconds to allow the Detector’s sensors to normalize to
the
environment’s spectral background conditions.
FSX Testing
- As with any intelligent flame or fire Detector, please wait a minimum of
thirty (30) seconds between tests (i.e., butane lighter, FSC test lamp, or test fires) to
allow the Detector’s sensors to fully normalize to the spectral background conditions.
Changing the Detector Settings
– To activate changes to the settings using SW1,
SW2 and SW3, reset the Detector by cycling (OFF, then ON) 24 VDC input power.
1. Make sure that the external 24 VDC input power is turned
U
OFF
U
before connecting the Detector.
2. Avoid wire splices. However, if wire splices are required, all splices should be soldered and properly
insulated. The use of good wiring practices simplifies installation, improves reliability and facilitates
maintenance.
3. For applications requiring analog/digital communications, please refer to Section 3.2 of this Instruction
Manual.

Installation Practices
U
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.
IMPORTANT
U
: 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 “weather-proof” integrity and satisfy local/regional regulations.
