PageFirst: Emergency Page Priority
This optional feature interfaces with an independent classroom paging 
system. When the page is broadcast, the system is muted, ensuring important 
and emergency school-wide messages are never missed.
How it works:
1. PageFirst sensor clip is hung around the lead wires attached to the in-room 
 paging speaker.
2. The clip is hard-wired to the 850iR.
3. As a page is broadcast, the sensor clip detects the audio signal though 
 induction and immediately mutes the 850iR.
4. When the page is over, the audio to the 850iR returns to normal.
 (For full installation instructions refer to the install sheet included with the 
 optional PageFirst sensor.)
