The fl ame detector has an angle of view of approximately 90°, as shown in the diagram
below.
Fig 2 Angle of view of XP95 Flame Detector
The fl ame detector should be positioned at the perimeter of the room, pointing directly at
the area of the anticipated fl ame or at the centre of the area to be protected. If the detec-
tor cannot 'see' the whole of the area to be protected, one or more additional detectors
may be required.
The fl ame detector is not affected by normal light sources but should be positioned so that
sunlight does not fall directly onto the viewing window.
Loop Design
The XP95 fl ame detector is powered from the loop; it draws 2.2mA in quiescent state and
4.2mA in alarm. In order to determine the number of fl ame detectors that can be con-
nected to a given loop, please refer to the Loop Calculation program, which can be
downloaded from the Apollo website or requested from Apollo's Technical Sales depart-
ment as a CD.

Address Setting
Before installing the fl ame detector it is necessary to set the address using the DIL switch,
which is accessed by removing the front cover, using a 5mm hexagonal key. 7 segments of
the switch are set to 0 or 1, using a small screwdriver or similar tool.
A complete list of address settings is shown in the following table.

Table 2 DIL switch address settings
We recommend that the address be set before the fl ame detector is mounted on the wall.
Sensitivity Setting
The eighth segment of the DIL switch referred to in the previous section is used to set the
sensitivity of the fl ame detector to class 1 or class 3. For most practical purposes the switch
should be set to class 1, the sensitivity required to detect fl ames as described in the section
'Quantities required and positioning of detectors'.
In exceptional cases the fl ame detector may be set to class 3 operation in order to avoid
nuisance alarms being caused by radiation sources that are close to the detector and
cannot be moved.
To set the DIL switch to class 1, switch to position '1'. To set to class 3, switch to position '0'.
Installation
The fl ame detector is mounted using either the mounting plate, which is supplied with the
detector, or the adjustable mounting bracket, part no 29600-203, which is bolted to the
mounting plate.
The standard mounting plate (supplied) is used for horizontal viewing, eg, along corridors or
along the length of industrial processes or vertical viewing inside fume cupboards or over
hoppers. It has two fi xing holes of 8.5mm diameter at 74mm centres.
