The IR
Flame Detector can also be ceiling mounted, positioned above the anticipated
³
flame source or at the centre of the area to be protected, perpendicular to the floor
below. If the detector cannot see the whole of the area to be protected, one or more
additional detectors may be required. Refer to the angle of view diagram Fig. 3 to establish
the detector performance. The area of detection is dependent on the detectors height
above the likely source of flame. The detector has a 90° conical field of view or 45° either
side of the viewing axis centre line. The maximum ceiling height is 20m.
If the detector is perpendicular to floor and at a height of 10m then the detector will view a
circular floor area below with a 10m radius (20m diameter circle).

To meet the requirements of EN54:10 clause 5.4, were the ratio of the response points
Dmax:Dmin should not exceed 1.41. The horizontal and vertical viewing angles a
not exceed ±32.5
Loop design
The IR
Flame Detector is powered from the loop; it draws 2.5mA in quiescent state and
³
4.2mA in alarm. In order to determine the number of flame 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.
