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.
The detector is factory sealed. While conduit seals are
not required for compliance with explosion-proof
installation requirements, steps must be taken to
prevent water ingress into the junction box area. Units
with M25 threads must use an IP66 washer.
MOUNTING AND WIRING PROCEDURE
IMPORTANT
If installing an X3300 in place of an existing
detector, be sure to move the “A” Lead (detector
power) at the controller from the +290 VDC
source to the +24 VDC source. Do not apply
290 VDC to the X3300.
Refer to the procedure below and the listed figures to
mount and wire the X3300.

PLATE ORIENTATION
Refer to Figure 2 and insure that the
oi
plate will be
oriented as shown when the X3300 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. The
oi
plate includes an arrow,
which should be pointed in the up direction, indicating
that the
oi
plate and detector are correctly oriented.
IMPORTANT
The
oi
plate must be securely tightened to ensure
proper operation of the
oi
system (40 oz./inches
recommended).
INSTALLATION PROCEDURE
1.
Install the mounting bracket assembly on the wall.
The installation surface should be free of vibration
and suitable to receive 1/4 inch (M6) screws with a
length of at least 1 inch (25 mm).
2.
Attach the detector to the mounting bracket and
tighten the nut to secure it in place. Refer to
Figures 3A, 3B, 4A and 4B.
