INSTALLATION MANUAL
Paging & Door Chime Using Two Independent Stereo Systems
These connections apply to both Pre-Amp/PowerAmp Systems and Stereo Receivers with
Pre-Out/Main-In jacks. This scenario requires the use of an automatic (signal-sensing) line
level A/B switch such as the Sonance AL-2 or the Niles SAS-1. Depending on the A/B switch,
a slight time lag between the activation/deactivation of the page and doorbell signals between
System #1 and System #2 may occur. Consult the manufacturer of the A/B switch for time lag
specifications.
