Mounting and wiring procedure – Det-Tronics X3300 Protect-IR Multispectrum IR Flame Detector User Manual

Page 7

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. Conduit seals are not
required for compliance with explosion-proof installation
requirements. Units with M25 thread must use an IP66
washer to prevent water ingress.

MOUNTING AND WIRING PROCEDURE

Refer to the procedure below and the listed table and
figures to mount and wire the X3300.

PLATE ORIENTATION

Refer to Figure 5 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

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

plate must be securely tightened to ensure

proper operation of the

system (40 oz./inches

recommended).
