Optional PageFirst Interface
This optional feature interfaces with an independent classroom paging system.
When the page is broadcast, all audio from the system is muted, ensuring
important and even emergency school-wide messages are never missed.
How it works:
1. PageFirst sensor clip is hung
around the lead wires attached
to the classroom paging
speaker.
2. The clip is hard-wired to the
REDCAT Media.
3. As a page is broadcast, the
sensor clip detects the audio
signal through induction and
immediately mutes the REDCAT
Media.
4. When the page is over, the audio
from the REDCAT Media returns to
normal volume level.
(For full installation details refer to the install sheet included with the optional
PageFirst sensor clip)
