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-12-HS provides Hydrogen Sulfide detection and automatic exhaust fan control for refineries, pulp and paper mills, waste
disposal or other commercial applications. Hydrogen Sulfide or H2S, also called sewer gas, is a colorless gas with a strong odor of
rotten eggs. Note: Sense of smell becomes rapidly fatigued & can NOT be relied upon to warn of the continuous presence of H2S. The
TX-12-HS is designed to meet the NIOSH and OSHA standards for Hydrogen Sulfide exposure limits. TX-12-HS can be used stand
alone, with the Macurco DVP-120 Detection and Ventilation Control Panel, other 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-12-HS is not intended for use in hazardous locations. Do not mount the TX-12-HS where the normal ambient temperature is
below 0°F or exceeds 125°F (below -18C or above 52C). The TX-12-HS mounts on a 4x4 electrical box supplied by the contractor.
Do not install the TX-12-HS 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-12-HS is a low voltage, dual relay Hydrogen Sulfide (HS) detector and automatic ventilation controller. The TX-12-HS uses a
microcomputer controlled, electronic system to measure the concentration of Hydrogen Sulfide, actuate relays and provide a 4-20mA
output. The TX-12-HS has a field replaceable, electrochemical sensor (expected life of 2+ years) and optional gas test and calibration
kits. The TX-12-HS is a low level meter capable of displaying from 0-50ppm of Hydrogen Sulfide.
