INSTALLATION AND STARTUP
NOTICE
These guidelines are ONLY intended as a general directive for the placement of the OI-6000. This information should NOT serve as a complete list when considering all potential parameters for the proper location of the unit. It is STRONGLY advised that a third party Certified Industrial Hygienist, or other Certified Safety Professional, conduct a site survey and annotate the location and quantity of detection devices that should be installed for EVERY installation of EVERY site.
2 INSTALLATION AND START-UP
2.1 PRODUCT PLACEMENT
The installation instructions, and any other information supplied by Otis, provide only basic guidelines relating to the properties of toxic gas and the effects of environmental conditions on the OI-6000 device. Sensor placement should be determined in consultation with the site safety personnel, as well as those knowledgeable of: (1) the site/facility where the equipment is being installed and (2) the potentially present gas types and their dispersion. Otis strongly recommends that the end-user consults with the appropriate third party Health, Safety and Environmental (HSE) and Industrial Hygiene (IH) professionals to determine the final quantity and placement of your gas detection devices.
The primary purpose of the OI-6000 is to provide an early warning of the accumulation of hazardous gas, in order to minimize hazards to people and property. Proper placement of the device is paramount to achieving this goal.
The following general guidelines should be considered when determining the placement of the OI-6000:
Units with a radio installed should be placed greater than 6.5 Feet/2 Meters away from a monitor in order to
ensure reliable communications
The unit shall be placed such that the position of the sensor housing is pointing downward to the ground. Avoid installing the unit in a location where airborne particles could cover or coat the sensor head. The unit should be placed in an area that will produce the highest gas concentration. Enclosed corners and
stopping points of moving devices are two areas susceptible to a buildup of hazardous gas.
In order to provide an accurate representative sample of a room, care should be taken to avoid locating the
unit near a room entrance, fresh air intake vent, or vehicle/generator exhaust point.
The unit should be placed as close as physically possible to the source of the potential hazardous gas leak. In consideration of possible ignition points, the unit should be placed between the potential leak source and
ignition point.
Consider placing the unit in a seldom used area, such as a warehouse, storage area, or other unfrequented
location.
Consider accessibility for regular calibration and other required maintenance. When monitoring a ventilated gas cylinder storage area, the unit should be placed near the air return vent. When monitoring an outdoor or open-air area, the unit should be placed near the air intake of the HVAC
system of the building.
When monitoring for the potential presence of multiple hazardous gas types, the unit should be calibrated for
the least cross-sensitive hazardous gas.

2.2 PRODUCT MOUNTING
It is recommended to mount the unit to a solid structure (such as a concrete wall, steel column, or angle iron) where a minimum of vibration will be transmitted to the unit. Alternately, a pole may be used along with a strap or a U-bolt, as long as it is rigid and of sufficient strength. Wooden structures are not recommended for mounting, as they trap moisture (which could affect sensor performance) and their mounting rigidity degrades over time (screws/bolts weaken and fall out or corrode).
Any style of bolt or screw may be used as long as it is steel and meets or exceeds the following:
Maximum ¼"-20 bolt or ؼ" screw (length varies with user need) Flat washers for bolts/nuts/screws Minimum Grade 5 (or better) Corrosion protection for all hardware (paint, galvanize, zinc plating, etc.)
2.3 WIRING CONFIGURATIONS
The OI-6000 has several basic wiring configurations, dependent upon the desired usage and functionality intended by the end-user. All OI-6000 units require +12 to +35 Volts of wired DC power to operate. Data communication from the device, through either the 4-20 output or the RS-485 Modbus connection, to an external location are optional. Consult the subsequent sections of wiring instructions for pertinent information and guidelines pertaining to the installation of your device.
