3.0 Installation
3.1 Sensor Placement
Coverage
Guidelines for sensor placement of diffusion type sensors are
based on the reasonable delay for gas to get from the source to
the sensor. All sensors 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)
since they can escape more quickly and the risk is greater.
The radius of coverage of any sensor 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,
anothersensor(s)isrequired.
Mounting Heights
Mounting heights for gas sensors 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,helium.
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 detectors combined with
nitrogendioxidedetectorsareinstalledat3to5feet(1
to2meters)fromtheoorwhentheceilingis7to10feet
high. If the ceiling height is higher than 10 feet, for example

for heavy equipment, the carbon monoxide detectors are
installedat3to5feet(1to1.5meters)fromtheooras
per the requirements of the Canada building code and the
nitrogendioxidedetectors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 detectors should be installed at 3 to 5 feet
(1to1.5meters)fromtheoor.Inallcasesthedetectors
must be installed above obstructions blocking circulation of
air in front of the detectors; 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),butane.Install1-3feet(30cmto1meter)fromoor.
For all types of sensors 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 Detection 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 sensors to one transformer. Ensure that the polarity of the
AC connections is the same at each sensor or controller, otherwise
communication between sensors 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 sensors, 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
sensor 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.

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 sensors are communicating correctly, change setting

no. 56 on one unit. Press →untill you reach 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 sensor connected
in order of their address. If the unit does not display the other
sensors scrolling by, check the following;
