Liquid in the <br />annulus could mean a dangerous leak. When liquid <br />is detected, the sensor sends an alarm signal to a <br />TLS -350, ILS -350, TLS-300i,TLS-250i Series or ILS - <br />250 monitor. The monitor's visual and audible built- <br />in alarm indicators immediately tell you where the <br />problem is, so you can quickly take action to help <br />prevent serious safety and environmental problems. <br />The TLS -350, ILS -350, TLS -300i, TLS -300i Series <br />and ILS -250 Systems feature internal alarm relays <br />that can also trigger on-site alarms for even greater <br />warning capability.
