 Spacing and Location
The number of detectors and their locations in the protected area are
affected by:
 Size of the protected area
 Sensitivity of the detectors
 Obstructed lines of sight
 Cone of view of the detectors
 Environment
 Dust, snow or rain can reduce the detectors sensitivity and require
more maintenance activities.
 The presence of high intensity flickering of IR sources may affect
sensitivity.
6.3 Preparations for Installation
Installation should comply with NFPA 72E or local regulations, as applicable
to flame detectors. The detectors can be installed with the use of
general-purpose common tools and equipment.
1 The detector package includes Detector assembly, Tilt Mount
P/N 768004, Protective Cover P/N 768005 and 3 mm Hex Key.
Since this detector is for indoor applications only, do not assemble the
Protective Cover unless it is necessary.
2 Verify the appropriate Purchase Order. Record the Part No. and the
Serial No. of the detectors and the installation date in the appropriate
Log-book.
3 Open the container package prior to detector installation and visually
inspect the detector.
4 Verify that all components required for the detector installation are
readily available before commencing the installation. If the installation is
not completed in a single session, secure and seal detectors and
conduits.
5 For wiring, use color-coded conductors or suitable wire markings or
labels.
16 to 22 AWG (0.4 mm² to 1.4 mm²) wires may be used for site wiring. The
selection of wire gauge should be based on the number of detectors used on
the same line and the distance from the control unit, in compliance with
specifications.
