Tempo PE620-G Tone Generator Alarm Loop Verifier has been designed specifically as a security and alarm continuity tester. This tone generator can be connected to a Normally-Open or Normally-Closed loop pair and provides a distinct audible tone when the alarm condition occurs.
Latching feature identifies intermittent failures and confirms operation of switches at remote locations. In latching mode, the Loop
Verifier will catch the alarm condition and continue until the tester is reset.
