Product information
The Marine Series 65 Base Mounted Ultraviolet (UV) Flame Detector
is designed to protect areas where flaming fires may be expected.
The detector is sensitive to UV radiation emitted by flames during
combustion. Since it requires only UV radiation the flame detector
responds even to stationary flames with no flicker like cigarette
lighters and blue gas flames.
The detector is set to respond to UV radiation (185 to 260 nm)
emitted by almost all flames including those invisible to the naked
eye, e.g. hydrogen fires.
The detector has a single UV sensor with a narrow spectral
response in order to discriminate between flames and most
spurious sources of radiation and is designed for use in internal,
fully enclosed areas.
CAUTION: The detector will also detect electrical discharges
from lightning or arc welding.

Electrical considerations
The detector signals an alarm state by switching an alarm latch
on increasing the current drawn from the supply from 550 �A
to a maximum of about 75 mA. This fall in the impedance of the
detector is recognised by the control panel as an alarm signal.
The alarm current also illuminates the detectors integral LEDs. A
remote indicator connected between the L1 In terminal and the -R
terminal will have a voltage equal to the supply voltage less one
volt across it and so will illuminate.
To ensure correct operation of the detector the control panel must
be arranged to supply a maximum of 33 V dc and a minimum of
12 V dc in normal operation.
The supply may fall to 6 V dc in alarm conditions if a supply current
of at least 10 mA is available at this voltage.
To ensure eective illumination of the integral LEDs and any
remote indicator, the supply to the detector should exceed 12 V.
To restore the detector to quiescent condition, ensuring all flames
are extinguished interrupt the supply to the detector for a minimum
of one second.
Note: When using the detector the following must be avoided; outside
viewing, UV lamps, electrical sparking, welding and sources of
radiation, UV light sources, prolonged ambient temperatures above
60ºC and obstructions to the field of view.
Applications for UV flame detectors
UV flame detectors are designed for use in enclosed spaces and
require a clear line of sight within the area to be protected. They
are unaected by draughts or convection currents.
They are fast acting and respond to a flame more than 25 m away
(refer to Figure 1).
Installation
If fitting to an XP95 Zone Monitor do not fir more than one device
per zone.
If fitting to a conventional control panel please verify the quantity
per zone with the panel manufacturer.

Figure 2: Ceiling mounting example
The flame detectors can also be ceiling mounted, positioned above
the anticipated 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 -
Figure 2 - 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 90º conical field of view or 45º
either side of the viewing axis centre line. The maximum ceiling
height is 20 m. If the detector is perpendicular to the floor and at
a height of 10 m then the detector will view a circular floor area
below with a 10 m radius - 20 m diameter circle.
