Det-Tronics X3302 Multispectrum IR Flame Detector - Manual (Page 8)

95-8576 6 9.2
DETECTOR ORIENTATION
Refer to Figure 2 and ensure that the
oi plate will be
oriented as shown when the X3302 is mounted and
sighted. This will ensure proper operation of the oi
system and will also minimize the accumulation of
moisture and contaminants between the oi
plate and the
viewing windows.
IMPORTANT
If removed, the oi
plate must be securely
tightened to ensure proper operation of the oi
system (40 oz./inches [28.2 N .cm] recommended).
pROTECTION AgAINST MOISTURE DAMAgE
It is important to take proper precautions during
installation to ensure that moisture will not come in contact
with the electrical connections or components of the
system. The integrity of the system regarding moisture
protection must be maintained for proper operation and
is the responsibility of the installer.
If conduit is used, we recommend installing drains,
according to local codes, at water collection points to
automatically drain accumulated moisture. It is also
recommended to install at least one breather, according
to local codes, at upper locations to provide ventilation
and allow water vapor to escape.
Conduit raceways should be inclined so that water will
flow to low points for drainage and will not collect inside
enclosures or on conduit seals. If this is not possible,
install conduit drains above the seals to prevent the
collection of water or install a drain loop below the
detector with a conduit drain at the lowest point of the
loop.
Conduit seals are not required for compliance with
explosion-proof installation requirements, but are highly
recommended to prevent water ingress in outdoor
applications. Units with M25 threads must use an IP66/
IP67 washer to prevent water ingress.
WIRINg pROCEDURE
Wire Size and Type
The system should be wired according to local codes.
The wire size selected should be based on the number
of detectors connected, the supply voltage and the
cable length. Typically 16 AWG or 2.5 mm 2 shielded
cable is recommended. Wires should be stripped 3/8
inch (9 mm). A minimum input voltage of 18 Vdc must
be present at the X3302.
NOTE
Re fe r to “ Powe r C o n s u m p t i o n” i n t h e
“Specifications” section of this manual.
The use of shielded cable is required to protect against
interference caused by EMI and RFI. When using cables
with shields, terminate the shields as shown in Figures
7 through 12, and Figure 15. Consult the factory if not
using shielded cable.
In applications where the wiring cable is installed in
conduit, the conduit must not be used for wiring to other
electrical equipment.
If disconnection of power is required, separate disconnect
capability must be provided.
CAUTION
Installation of the detector and wiring should be
performed only by qualified personnel.
Detector Mounting
Install the mounting arm assembly on a rigid surface. The
ideal installation surface should be free of vibration and
suitable to receive 3/8 inch or M10 bolts with a length
of at least 1 inch (25 mm). The surface must also have
sufficient capacity to hold the detector and mounting arm
weights (see "Specifications" section). Refer to the Q9033
Mounting Arm and Collar Attachment manual (95-8686)
for additional mounting information. See Figure 3 for
dimensions.
