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. The Matrix is designed for a 4-pulse system.
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
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
Testing the Security Alert function
To test security alert, you will need an IRT-60 (Sapphire™) microphone.
1. Turn on an IRT-60 Sapphire microphone by holding the power button
until it illuminates.
2. Once the LED is illuminated solid blue, locate the “Priority” switch on
the side of the microphone.
3. While looking at the amplifier’s power button, press & hold the
microphone’s Priority button for 5 seconds after which time the
amplifier’s power button will flash green. There will be an audible
clicking sound from the amplifier when flashing.
