Instructions
For the correct and effective use of this e

p
ment, to maintain safet
y
and avoid hazards
it is essential that you read and understand these instructions fully, act accordingly
BEFORE installing, operating or maintaining the equipment.
2.1
Warnin
g
s
This e
q
ui
p
ment is certified and intended for use in
p
otentiall
y
hazardous areas. Install and
use
the equipment in accordance with the latest regulations.
For Euro
p
ean (ATEX) installations IEC/EN60079-14
‘Electrical
Installations
in Hazardous Areas’
and
ICE/EN60079-17 ‘Inspection and Maintenance in Hazardous Areas’ should be strictly observed.
For installations in North
A
merica the National
Electrical
Code
(NEC)
should be strictl
y
observed.
In other countries the appropriate local or national regulations should be observed.
The e
q
ui
p
ment must be
p
ro
p
erl
y
earthed
to
p
rotect
a
g
ainst
electrical
shoc
k
and minimise
electrical interference.
Do not drill holes in any housing or enclosure as this will invalidate the explosion protection.
Ensure that the enclosure lid is fully tightened and locked into position before energising the
equipment.
Do not o

must
be

and
the e

O
p
erators must be

ro
p
erl

trained and aware of what actions to take in the event of a fire bein
g
detected.
Cable to be used for installation is to be selected with a temperature rating of greater than 25
degrees Celsius above the maximum ambient temperature. The metric cable entries are fitted
with an internal stop. This will result in threads of the cable gland being visible. Do not over
tighten.

2.2
Cautions
Use only approved parts and accessories with this equipment.
Do not attempt to replace the window as the glass and the front cover are individually matched
pairs to meet the stringent requirement of the Hazardous area certification.
The threaded portions of the detector are flame paths. These threads and the flame paths
around the window are not to be repaired.
To maintain safet

g
Do not open the detector assembly in a hazardous area when power is applied. The detector
contains limited serviceable components and should never be opened except by trained
personnel.
Caution
The wiring procedures in this manual are intended to ensure functionality of the device under
normal conditions. Due to the many variations in wiring codes and regulations, total compliance
to these ordinances cannot be guaranteed. Be certain that all wiring complies with the all local
ordinances. If in doubt, consult the authority having jurisdiction before wiring the system.
Installation must be done by trained personnel.
Caution
To prevent unwanted actuation or alarm, extinguishing devices must be inhibited/isolated prior
to performance testing or maintenance.

Detector Orientation
Detectors should be mounted with the earth stud/status led directly below the lens to ensure the
120° horizontal field of view is achieved.
Detector Positionin
g
Detectors should be positioned to provide the best unobstructed view of the area to be
protected.
The followin
g
factors should also be taken
into
consideration:
•
Identif
y
all hi
g
h risk fire i
g
nition sources. Ensure that enou
g
h detectors are used to
adequately cover the hazardous area.
•
Locate and
p
osition the detector so that the fire hazard(s) are within both the field o
f
view and detection range of the device.
•
For best
p
erformance, the detector
should
be
mounted
on
a
ri
g
id surface in a low
vibration area.
•
Extremel
y
dense fo
g
or blizzard
conditions
could
eventuall
y
block the vision o
f
the
detector.
•
For indoor a
pp
lications, if dense
smoke is ex
p
ected to accumulate at the onset of a
fire,
mount the detector on a side wall (approximately 1 metre, 3 feet) down from the ceiling.
•
The FS301 flame simulator can be used to verif
y
correct detector
p
ositionin
g
and
coverage.
•
The FDS300 has

,
this

•
The detector carries out continuous
internal
hardware
dia
g
nostic testin
g
to ensure
correct operation is relayed to the control system.
•
The FDS300 is not designed to annunciate diagnostic failures of signal returns via
external wiring. Control systems and fire panels generally have fault monitoring for
such an eventuality.

Installation
The FDS300 design has been developed to allow simple installation. The detector comprises
two key components, the detector enclosure and the detector internal assembly. The detector
assembly located in the front of the enclosure should not be removed except by trained
personnel. Unauthorised removal or disassembly of the detector assembly will invalidate the
warranty. Only the rear end cap can be removed for terminal access.
3.1
Detector Enclosure
The detector electronics are housed in an enclosure certified for use in hazardous areas. For
the exact certification and conditions of use see certification label on the device, or the exam

Firm, vibration free mountings are essential for trouble free operation of optical systems and the
detector should be fixed to a rigid mounting. When mounting on a wall in this orientation allow
for the cable gland and cable as this may restrict the downward rotation of the detector.
