voltage and the cable length. Typically 16 AWG,
2.5 mm

shielded cable is recommended. Wires
should be stripped 1/2 inch (12 mm). A minimum
input voltage of 18 Vdc must be present at the
X3302.
NOTE
Refer to “Power Consumption” in the
“Specications” 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 8 through 13 and
Figure 16. 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.
WARNING
All entries must contain appropriately rated
plugs or fittings. It is required that each
plug or fitting be wrench-tightened to an
appropriate installation torque and meet the
minimum thread engagement requirements
per the applicable local standards, codes,
and practices in order to retain the dened
ratings. PTFE sealant or equivalent should
be used on NPT threads.
IMPORTANT
Devices certified for hazardous locations
shall be installed in accordance with EN/
IEC 60079-14 and NEC 505.
CAUTION
Installation of the detector and wiring
should be performed only by qualified
personnel.
Detector Installation
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,
number 95-8686, for additional installation
information. See Figure 3 for dimensions.
Relay and 0–20 mA Output Models
Follow the instructions below to install the X3302.
1. Make field connections following local
ordinances and guidelines in this manual.
– Figure 4 shows the wiring terminal strip
located inside the detector’s integral
junction box.
– Figure 5 shows the wiring terminal
identification for the X3302 Flame
Detector.
– Figure 6 shows a resistor installed within
the integral wiring compartment of the
detector (refer to “EOL, Fire, and Fault
Resistors” for details).
– Figures 7, 8, and 9 provide examples of
typical installations with a X3302 wired to a
fire alarm panel.
– If the detector is equipped with a 0–20 mA
output, refer to Figures 10 through 13.
2. Check all field wiring to be sure that the
proper connections have been made.
IMPORTANT
Do not test any wiring connected to the
detector with a meg-ohmmeter. Disconnect
wiring at the detector before checking
system wiring for continuity.
3. Make the final sighting adjustments and
use a 14 mm hex wrench to ensure that the
mounting arm assembly is tight.
EOL, Fire, and Fault Resistors (Not Used
with EQP Model)
To ensure that the insulating material of the wiring
terminal block will not be affected by the heat
generated by resistors, observe the following
guidelines when installing the resistors.
1. Resistors must be rated appropriately for
the application and have a maximum power
dissipation of 5 watts.
NOTE
This applies to ATEX/IECEx installations only.
