1.2 WARNINGS
•Calibrate TXP-WTA Sensor Transmitters that communicate to the TracXP wireless monitoring system with a
known concentration of gas at start-up. Check calibration on a regular schedule (at least every 90 days).
More frequent inspections are encouraged to spot problems such as dirt, oil, paint, grease or other foreign
materials on the sensor filter.
•Do not paint any part of the TXP-WTA Sensor Transmitter or corresponding components.
•Do not use the TXP-WTA Sensor Transmitter if any enclosure is damaged or cracked or has missing
components.
•Make sure covers, internal boards, and antenna connections are securely in place before operation.
•Use only approved Smart Sensor Modules that are compatible with the TXP-WTA Sensor Transmitter.
•Periodically test for correct operation of the system’s alarm events by exposing the TXP-WTA Sensor
Transmitter to a known concentration of gas above the High Alarm set-point.
•Do not expose TracXP devices to electrical shock or continuous severe mechanical shock.
•Protect TracXP devices from dripping liquids and high-power sprays.
•Use only for applications described within this manual.

power may be set from 10mW to 1 watt (see Section 8.1.9)
NOTE: 1-watt operation is not recommended or necessary for most applications as it can cause an unnecessary load
on the battery thereby significantly reducing battery life.
Power Consumption (2.4 GHz Models)
2mA during “sleep” mode, 170mA during 125mW broadcasts.
2.4.7.2 Maximum Transmit (TX) Power (900 MHz Models (EIRP based on a 2dBi gain antenna))
30dBm at highest 1W power setting. Transmit power may be set from 10mW, 200mW, 400mW and 1 watt (see
Section 8.1.9)
NOTE: 1-watt operation is not recommended or necessary for most applications as it can cause an unnecessary load
on the battery thereby significantly reducing battery life.
2.4.7.3 Maximum Transmit (TX) Power (2.4 GHz Models (Conducted; no antenna))
Transmit power is fixed at 125mW (21dBm)
2.4.7.4 Receive (TX) Sensitivity (900 MHz Models)
100 dBm
2.4.7.5 Receive (TX) Sensitivity (2.4 GHz Models)
95 dBm
2.4.7.6 Radio Frequency (900 MHz Models)
Hopping occurs between 902 – 928 MHz
2.4.7.7 Radio Frequency (2.4 GHz Models)
Hopping occurs between 2400 – 2483.5 MHz
