WIRELESS H2S TRANSMITTER (WT SERIES) - USER GUIDE
2. PRODUCT OVERVIEW
Integrated H2S Detection Solution
The OleumTech® OTC Wireless Hydrogen Sulfide (H2S) Gas Detection
Transmitters are self-contained, battery-powered solutions for continuously
monitoring air quality and generating alarms when H2S concentration levels
exceed user-configured setpoints. The H2S Transmitter integrates an
individually calibrated modular H2S sensor and can be replaced easily and
quickly. It also provides additional sensor maintenance tags like bump test
count, total days since last successful bump test and calibration. The H2S-A
option provides two solid state relay outputs for third-party device alarm
annunciation.
The local user interface allows for device configuration and instant data access.
Bump tests and alarm acknowledgments can be performed using just the
external scroll button.
Reliable, Scalable, and Safe
The field-proven wireless transmitters communicate with an assigned wireless
gateway within the OTC Wireless Sensor and I/O Network creating a highly
scalable network, accommodating virtually any I/O requirement. The
OleumTech wireless transmitters are Intrinsically Safe and certified for use in
Class I, Division 1 (Zone 0) hazardous locations.
The H2S Transmitters provide separate controllable transmit intervals for both
normal and alarm states. For exception reporting purposes, event-triggered
transmissions will be reported when going into or falling out of alarm states.
The alarm states are latchable.
