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.)
