Important Information !
This manual provides information required to install, operate and
maintain the series 6000 gas monitoring system. Read and study
before attempting to install or operate monitors. Installation
and operation not in accordance with this manual can result in a
hazardous situation or harm. Relay connections may be used to
control 120 Vac equipment. Ensure power is disconnected from
relays before attempting to service this unit.
1.0 General Description
Series 6000 gas monitors provide air quality monitoring for
commercial properties. Close monitoring of indoor air-born
pollutants and automatic fresh air controls improve the health and
well being of occupants and, also minimize excess ventilation,
reducing both energy costs and maintenance costs. The key to
maintaining this balance is a high level of precision coupled with a
robust design suited to tough commercial applications.
Each 6000 monitor can measure one or two gases and control
ventilation directly. They communicate with each other (up to 32)
via the chain network, so some monitors activate the ventilation
and others send the commands. The monitors are easily assigned
to groups on site for ventilation zoning on the same network. This
reduces control wiring signicantly.
The use of this peer-to-peer CAN network eliminates the need for a
costly controller on smaller projects. For the larger ones, a 6000-B
controller or addressable relay units can be added where starters
are centralized in the mechanical room. The monitors can also be
tied into a BACnet building automation system by simply connecting
an MS/TP cable to any monitor or 6000 controller on the CAN
network. The gas readings from all the monitors will display on the
BMS and the BMS can over-ride output relays on the monitor it is
connected to.

3.0 Installation
3.1 Monitor Placement
Coverage
Guidelines for placement of diffusion type monitors are based on
the reasonable delay for gas to get from the source to the sensor.
All monitor sensors combinations are created equal in this regard.
• For air quality control of exhaust emissions and
accumulations of toxic gases the generally acceptable
maximum radius of coverage is 50 feet (15 meters).
Approximately 7500 square feet (700 square meters).
• For leak detection of combustible gases, ammonia,
refrigeration gases the maximum radius is 30 feet (10 meters).
The radius of coverage of any monitor does not extend beyond
any obstruction that impedes natural circulation of air. This
includes walls, stairs, elevators, shelving with solid ll, tool
chests, etc. The sensor must “see” the area of coverage; if not,
additional monitors are required.
Mounting Heights
Mounting heights for gas monitors are based on their density,
relative to air. There are three groups;
1. Lighter than air and will be more concentrated near the
ceiling; hydrogen, methane (natural gas), ammonia.
Install at 1 to 3 feet from ceiling.
2. Similar density to air and will be diluted in air equally at
all levels; - carbon monoxide, nitrogen dioxide, hydrogen
sulde, oxygen, carbon dioxide. Install from 3 feet (1
meter) off oor to one half of the ceiling height. For vehicle
emissions carbon monoxide sensors combined with nitrogen
dioxide sensors are installed at 3 to 5 feet (1 to 2 meters)
from the oor when the ceiling height is 7 to 10 feet. If the
ceiling height is higher than 10 feet, example- for heavy
equipment, the carbon monoxide monitors are installed

at 3 to 5 feet (1 to 1.5 meters) from the oor as per the
requirements of the Canada building codes and the nitrogen
dioxide monitors should be installed at 50% of the ceiling
height and above the vehicle height. If the exhaust pipes
of diesel vehicles are below the vehicles, then the nitrogen
dioxide monitors should be installed at 3 to 5 feet (1 to 1.5
meters) from the oor. In all cases the monitors must be
installed above obstructions blocking circulation of air in
front of the monitors; example, maintenance garages in
automobile dealerships where tool chests, work tables and
storage racks typically line all walls.
3. Heavier than air and will concentrate near the oor; - HFCs,
HCFCs, propane, chlorine, most organic vapors (consult
Opera). Install 1-2 feet (30cm to 50cm) from oor.
For all types of monitors avoid drafts, obstacles, aerosols, silicones.
Place sensors in the center of its coverage area as much as
possible.
