GAS DETECTION

For monitoring gas concentrations in wash bays

Protection Mounted Gas Detection

The Macurco WHK-1 is a weatherproof enclosure that provides means to protection-mount all Macurco 6-Series
gas detectors in non-hazardous locations. By weatherproofing a gas detector, the unit is able to monitor gas
concentrations while being protected from falling debris and indirect spray. The Macurco WHK-1 is designed with
sufficient airflow for effective gas detection through multiple vent plugs.

3. Place the enclosure onto the wall to test for proper alignment.

4. Place the unit against the wall in its intended position.

5. Fasten the enclosure to the wall by installing the 4 mounting screws.

6. Run the wiring through the strain relief.

7. Connect the wiring according to the instructions provided for the detector.

8. Install the gas detector onto the top of the 4 standoffs. Secure it in place using the 4 remaining machine screws.

9. Twist the outer cap of the strain relief clockwise to compress the gasket material around the wiring.

10. Replace the cover and tighten the cover screws.

Application

The enclosure is constructed for either indoor or outdoor use to provide a degree of protection of the equipment inside the

enclosure against ingress of solid foreign objects (falling dirt and debris) and to provide a degree of protection with respect

to harmful effects on the equipment due to the ingress of water (light rain, spray, dripping and light splashing).

Nitrogen Dioxide

Nitrogen dioxide or NO

2 is a toxic chemical of concern in diesel exhaust. The higher average temperature of combustion of

diesel engines generates more nitrogen oxides than gasoline engines. At ordinary temperatures and atmospheric pressure,
it is a reddish-brown gas with a characteristic sharp, biting odor. High concentrations of the oxides of nitrogen can cause
headache, dizziness and loss of consciousness as well as pulmonary edema. Health concerns about diesel exhaust relate
not only to as respiratory and heart diseases, but also to other health problems. Lung cancer is the major cancer thought to
be linked to diesel exhaust. The Macurco TX-6-ND provides Nitrogen Dioxide detection and automatic exhaust fan control
for parking garages, loading docks, truck and bus depots, firehouses, ambulance bays, warehouses and maintenance
facilities. The TX-6-ND meets the requirements of the Uniform Building Code for enclosed garages and meets OSHA
standards for Nitrogen Dioxide exposure. TX-6-ND can be used stand alone, with the Macurco DVP-120 Detection and
Ventilation Control Panel, other 12 VAC or 24 VDC fire/security panels or building automation systems.

Carbon Monoxide

Carbon monoxide or CO is a poisonous gas responsible for hundreds of deaths and numerous non-fatal poisonings each
year in the United States. It is a colorless, odorless, and tasteless gas that is produced as a by-product of incomplete
combustion of carbon-based fuels such as natural gas, liquefied propane (LP) gas, kerosene, oil, gasoline, wood, or coal.
The Macurco CM-6 provides CO detection and automatic exhaust fan control for automotive maintenance facilities,
enclosed parking garages, utility rooms, warehouses and other commercial applications. The CM-6 meets the
requirements of the Uniform Building Code for enclosed garages and meets OSHA standards for CO exposure. The CM-6
can be used stand alone, with the Macurco DVP-120 Detection and Ventilation Control Panel, other 12 VAC or 24 VDC
fire/security panels or building automation systems.
