Interesting. Got this reply from L&S Safety re Pressure Pro:
Thank you for your inquiry about the PressurePro system.
The PressurePro will alert you within a maximum time of about 5 minutes if you lose a sensor signal. You will receive an alert with three dashed lines in the display indicating that the sensor signal has been lost. This can happen in real world situations just through external interference so the sensor may be picked up on the next scroll by the monitor through all sensor locations in which case you will see the pressure reading as normal.
The sensors are sending a signal every 7 seconds to the monitor which updates the display every 5 minutes. During those five minutes, if there is an alert situation, you will be instantly notified on the display(within 7 seconds)
There should never be a case where you are not updated for any significant length of time to a lost sensor signal.
I hope this helps. Although, TST seems to have a decent product, over the years we have sold lots of PressurePro systems to previous TST owners.
I've attached a manual for you to look through which answers common questions and explains the operation of the system. Please feel free to contact me further if you have other questions.
