RE-232 and Security Alert contacts
The security Alert features allows the teacher/
presenter to send a silent wireless electronic
signal with a simple press of a button, in the
event of an in-classroom security incident. The
signal is easily generated by the teacher who is
wearing Sapphire wireless pendant microphone.
This same microphone transmitter which is used
for in-room amplification, has a special button
(labelled PRIORITY) on the side for initiating the
Security Alert. Simply holding down the button for
4 seconds, "closes" a contact closure on the rear
panel of the TeachLogic amplifier and sends the
Security Alert signal to the appropriate location
possibly the principal's or security monitoring
station. The front panel power switch on the
front of the amplifier will "blink" with a soft green
background.
To disengage from the Security Alert mode,
simply hold the side button for 4 seconds, and
the amplifier will return to its normal state with the
front panel power button illuminated with a solid
blue background.
The output is a three pin NO/NC contact closure
labeled Security Alert.
