Installation
This chapter does not attempt to cover all of the standard practices and codes of installation.
Rather, it emphasizes specific points of consideration and provides some general rules for qualified
personnel. You must always observe special safety precautions.
2.1
General Considerations
This section includes important information.
•
To help obtain optimal performance, the detector should be aimed toward the centre of
the hazard or area to be monitored and protected ("detection zone") and have, to the
extent that is required, an unobstructed view of the protected area. Whenever possible,
the detector face should be tilted (aimed) down at an angle to prevent the accumulation
of dust and dirt.
•
Do not start an installation until the performance target, system configuration,
installation location and coverage considerations have been defined by the responsible
person.
To ensure optimal performance the following guidelines should be addressed:
Sensitivity
To determine the sensitivity level, the following points should be considered:
•
The size of the fire is to be detected at the determined distance.
•
The type of flammable fuel.
Spacing and Location
Consider the following factors when determining the number of detectors and their locations in the
protected area:
•
The size and shape of the protected area
•
The nature of the hazards, including materials stored or used and the protected objects
•
The sensitivity of the detectors
•
If there are any obstructed lines of sight
•
The field of view of the detectors (See Figure 9 and Figure 10)
