Installation - MSA Ultima OPIR-5 Safety Manual

INSTALLATION

WARNING: Under NO circumstances should equipment be connected or disconnected
when under power. This is contrary to hazardous area regulations and may also lead to
serious damage to the equipment. Equipment damaged in this manner is not covered
under warranty.
For complete information on the installation of the Ultima OPIR-5 Gas Detector, refer to
the respective product instruction manual. Be sure to closely follow alignment
instructions.
Location Considerations
There are no standard rules for placement, since the optimum location varies with each
application. Some factors to consider when selecting locations:
•
The system should be accessible for occasional response checks. The line of
sight between the Source and Receiver units should be free from objects that
may block the beam and interruptions caused by frequent human or animal
crossings. The Receiver unit should be mounted so that the display is visible to
aid in alignment and so that direct sunlight does not enter the front window.
•
Do not mount near strong magnetic fields or degradation of performance may
result. Although the Ultima OPIR-5 Gas Detector is Radio Frequency
Interference (RFI) resistant, it should not be mounted too close to radio
transmitters or similar equipment.
•
The units should be reasonably protected (i.e. covered by a hood if temperatures
exceed the environmental specifications in the product instruction manual).
Mount away from sources of excessive vibration and away from high voltage/high
current power lines and from concentrated sources of heat.
An aperture plate is required if the open path length is less than 20 meters (Ultima OPIR-
5 Gas Detector standard range).
It is important to obtain the highest alignment number possible within the allowed range.
NOTE: Frequent inspection, cleaning, and sensitivity checking is suggested for gas
detectors mounted in dirty environments.
No special or additional detector mounting, wiring, power, or tool requirements exist
beyond the standard installation practices documented in the Ultima OPIR-5 Gas
Detector instruction manual.
