Security Alert Feature

The Security Alert feature allows a user with a TeachLogic wireless microphone to
summon help or indicate to administration personnel of an urgent situation in the room
of that user.
CONNECTION
• Uses wire from paging manufacturer's wall-mounted call button panel to connect to amplifier via 3-
pin Phoenix connector: COM | NORMALLY OPEN | NORMALLY CLOSED
Push/Hold for 5 seconds
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
Setting Security Alert pulses with slide switch
The pulse change can be made with a dedicated switch to select either 1-pulse or 4-pulse mode as required
by different security systems. Reference the label on the bottom of the amplifier for the settings.
