Specificity Results (in addition to above):
Sensors will respond to any hydrocarbon liquid after its threshold is exceeded.

Comments:
Sensors are reusable. Sensor is easily removed, cleaned, and reinstalled.
The consoles in the 8601 Series are identical other than their name for marketing purposes. Each of the consoles within the series will perform identically.
The 8601 Series consists of the following derivatives: TLS4, TLS4B, TLS4c, TLS4i, and TLS-S1 consoles.
The 794390-420 sensor is an interstitial sensor with a 16’ long cable for steel tanks with an inside diameter of 4’ to 12’. The 794380-430 sensor is an interstitial sensor with a 15’ long cable for steel tanks. The 794390-460 sensor is an interstitial sensor with a 30’ long cable for steel tanks with an inside diameter of 4’ to 12’. These sensors detect the presence of fluid in the interstice of a double-wall steel tank. If the liquid level rises above the threshold of these sensors in the interstice of a steel tank, an alarm condition is generated. This would indicate there is liquid present in the interstice area where the sensor is installed.
For all sensors, console alarm is indicated by an audible alarm, a displayed message and a printed message (if the console is equipped with a printer.) The alarm is also recorded as part of Alarm History Report.
