Environment
:
•
Dust, snow or rain can reduce the detectors sensitivity and require more
maintenance activities.
•
The presence of high intensity flickering IR sources may affect sensitivity.
•
Aiming the Detector
:
•
The detector should be aimed toward the center of the detection zone and have a
completely unobstructed view of the protected area.
•
Whenever possible, the detector face should be tilted down at a 45º angle to
maximize coverage and prevent accumulation of dust and dirt.
•
Do not start an installation unless all conceivable considerations regarding
detection location have been taken into account.
Installation should comply with
NFPA 72E or any other local and International
regulations and standards
, as applicable to flame detectors and installation of Ex
approved products.
2.2
Unpacking the Product
Upon receipt of your detector, check and record the following:
6
Verify the appropriate Purchase Order.
Record the Part Number (P/N) and Serial Number of the detectors, and the installation
date in an appropriate Log-book.
7
Open the package before installation and visually inspect the detector.
8
Verify that all components required for the detector installation are readily available
before beginning the installation. If the installation is not completed in a single
session, secure and seal the detectors and conduits / cable entries.
2.2.1
Checking the Product Type

For wiring, use color-coded conductors or suitable wire markings or labels. 12 to 20 AWG
(0.5 mm² to 3.5 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 (see
General Instructions for Electrical
Wiring
on page 40).
