My TST 507 system started beeping yesterday telling me I had a low battery in the left rear sensor. I just finished replacing it and putting it back on.
My question is: A previous post states that the 507 system can take up to an hour to warn of a lost signal from a sensor? The reason for the question mark is, when I remove a sensor for battery replacement which turns off the transmitter in the sensor (loss of air pressure turns the sensor off), the alarm goes off instantly. How is this different from a lost signal for other reasons? A lost signal is a lost signal, isn't it?
