INSTallaTION

NOTE

The recommended lubricant for threads and
O-rings is a silicone free grease (part number
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.

• Locate and position the detector so that the fire

hazard(s) are within both the field of view and

detection range of the device. Refer to Appendix A

for specific information.

• 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 field of view does not cover areas outside
the hazardous area.

This will minimize the possibility

of false alarms caused by activities outside the area

requiring protection.

• For best performance, the detector should be

mounted on a rigid surface in a low vibration area.

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

(see Table 2) can absorb UV radiation and reduce

the sensitivity of the detector.

• Verify that all detectors in the system are properly

aimed at the area to be protected. (The Det-Tronics

Q1201C Laser Aimer is recommended for this

purpose.)

• If possible, fire tests should be conducted to verify

correct detector positioning and coverage.

• For ATEX installations, the X2200 detector housing

must be electrically connected to earth ground.

DETECTOR ORIENTATION
Refer to Figure 2 and ensure that the oi plate will be

oriented as shown when the X2200 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

The

plate must be securely tightened to ensure

proper operation of the

system (40 oz./inches

recommended).
