INSTallaTION

NOTE

The recommended lubricant for threads and O-rings
is a silicone free grease (p/n 005003-001) available
from Detector Electronics. Under no circumstances
should a lubricant containing silicone be used.

DETECTOR pOsITIONINg
Detectors should be positioned to provide the best

unobstructed view of the area to be protected. The

following factors should also be taken into consideration:
• Identify all high risk fire ignition sources.
• Be sure that enough detectors are used to adequately

cover the hazardous area.

• Be sure that the unit is easily accessible for cleaning

and other periodic servicing.

• Verify that all detectors in the system are properly

located and positioned so that any fire hazards are

within both the Field of View (FOV) and detection

range of the detector. The Q1201C Laser Aimer

is recommended for establishing the detector's

FOV. Refer to Appendix A for specific information

regarding detector range and FOV.

• The detector should be aimed downward at least 10

to 20 degrees to allow lens openings to drain (see

Figure 1). The detector should be positioned so

that its FOV does not cover areas outside the
hazardous area.

This will minimize the possibility

of false alarms caused by activities outside the area

requiring protection.

• The detector must be mounted on a rigid surface in

a low vibration area.

• Dense fog, rain as well as certain gases and vapors

(see Table 3) can absorb UV and IR radiation and

reduce the sensitivity of the detector.

• If possible, fire tests can be conducted to verify

correct detector positioning and coverage.

• For ATEX installations, the X5200 Flame Detector

housing must be electrically connected to earth

ground.

DETECTOR ORIENTATION
Refer to Figure 2 and ensure that the

plate will be

oriented as shown when the X5200 is mounted and

sighted. This will ensure proper operation of the

system and will also minimize the accumulation of

moisture and contaminants between the

plate and the

viewing windows.

Important

If removed, the

plate must be securely

tightened to ensure proper operation of the

system (40 oz./inches [28.2 N .cm] recommended).
