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.

3.3 Installation Check List
Important. All wiring must conform to local building codes,
regulations and laws. If the equipment is used in a manner not
specied by the manufacturer, the protection provided by the
equipment may be impaired.
1. Use ½ inch EMT conduit for all wiring.
2. A switch or circuit breaker must be included in the installation. It
must be suitably located and easily reached in a secure location
and identied as the disconnect for the “Gas Monotoring System”.
3. Install enclosed 120/24 vac transformer. For the size of transformer
allow 5 va for each sensor or controller. Use 18 to 20 AWG two
conductor wire. Do not tie the secondary to ground. Connect
multiple monitors to one transformer. Ensure that the polarity of the
AC connections is the same at each monitor or controller, otherwise
communication will not function.
4. Connect relay contacts (usually relay 1) to ventilation system.
Use a magnetic starter so that the sensor contacts energize the
starter coil and not the fan motor directly.
5. For multiple monitors, inter-connected using the CAN network.
Connect a shielded twisted pair cable 22 to 24 AWG from
screw “L” and “H” (screw 11 and 12) on one sensor, to the next
monitor and continue chain to the last sensor. Maintain the same
polarity on each unit. Do not use star, T, or H junctions, only a
continuous chain. Make all chain connections at the sensors.
Connect shield to “S” on the rst sensor or controller only and
join shields together at each sensor/controller after the rst.
6. Move the end-of-line jumper (the one above terminal 11, 12) to
the on position (UP) on the rst monitor (or controller) on the chain
and the last monitor/controller on the chain. A controller with no
sensor module can be located anywhere on the chain. Ensure its
EOL jumper is off (down) if it is in the middle. Monitor/controller
addresses can be in any location on the chain.
7. Power on the units. They will display the gas type and reading.
To verify if monitors are communicating correctly, change setting

no. 56 on one unit. Press → until you reach option 56. Press → to
switch from 0 to 1, to turn on the network display. Press → and →
simultaneously to save, then press and hold → for a few seconds
to return home. The unit will display each monitor connected
in order of their address. If the unit does not display the others
scrolling by, check the following;
• each unit must have a unique address, setting 39, with no
duplicates
• end-of-line jumpers are set on units at ends of cable only
• polarity of the communication cable and the 24 Vac is the
same on all units
• verify wire connections for shorts, and loose wires, etc.
8. To further test communication, press and hold the up button on
a monitor for 5 seconds to start manual mode (5 minutes). This
will close the relay 1 on that unit and all of the other units on the
network. See section 5 to set up a conguration for multiple
zones.
