SYSTEM BEHAVIOR
When the Sapphire’s “Priority” button is pushed/held for 5
seconds, it sends a signal to the ceiling sensor which passes
through the amp to the security alert interface (an electric relay).
The relay contacts opens or close (depending on the normal
status) to pass the signal through the paging system as if the
paging system’s wall-mounted button was being pressed.
The amplifier functions normally during the alert, e.g. there is
no change to audio input/output volume change nor does the
system produce any sound
