USE INSTRUCTIONS AND LIMITATIONS
Each person using this equipment must read and understand the information in these User Instructions before use. Use of this
equipment by untrained or unqualified persons, or use that is not in accordance with these User Instructions, may adversely affect
product performance and
result in sickness or death.
Use For
The 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. 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. 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.
Use only for monitoring the gas which the sensor and instrument are designed to monitor. Failure to do so may result in exposures to
gases not detectable and
cause sickness or death
. For proper use, see supervisor or User Instructions, or call Technical Service at 1-
877-367-7891.
Do Not Use For
The TX-6-ND is not intended for use in hazardous locations or industrial applications such as refineries, chemical plants, etc. Do not
mount the TX-6-ND where the normal ambient temperature is below 0°F or exceeds 125°F (below -18
C or above 52
C). The TX-6-ND
mounts on a 4x4 electrical box supplied by the contractor. Do not
install the TX-6-ND inside another box unless it has good air flow
through it.
This equipment may not function effectively below 0
F or above 125
F (-18
C or above 52
C). Using the detector outside of this
temperature range may adversely affect product performance and
result in sickness or death
.
General Description
The TX-6-ND is a low voltage, dual relay Nitrogen Dioxide (ND) detector and automatic ventilation controller. The TX-6-ND uses a
microcomputer controlled, electronic system to measure the concentration of Nitrogen Dioxide, actuate relays and provide a 4-20mA
output. The TX-6-ND has a field replaceable, electrochemical sensor (expected life of 2+ years) and optional gas test and calibration
kits. The TX-6-ND is a low level meter capable of displaying from 0-20ppm of Nitrogen Dioxide.
