Optional PageFirst Kit
This 975 feature interfaces with an independent classroom paging system.
When a page is broadcast, all audio from the system is muted, ensuring
important school-wide messages are not missed. Please note that PageFirst
is not compatible with telephone or IP-based paging systems.
How it works:
1. PageFirst sensor clip is hung around a lead wire attached to the
classroom paging speaker.
2. The clip is hard-wired to the amplifier.
3. As a page is broadcast, the sensor clip detects the audio signal through
induction and immediately mutes the amplifier.
4. When the page is over, the audio from the amplifier returns to normal
volume level.
