The All Call mode is used to send a page to the entire facility.
When the All Call switch is activated, the Audio Source Unit is
put into the all call mode. In this mode, the zoned audio
amplifiers do not all transfer to the page channel. Rather, the
Audio Source Unit redirects the page signal source to all the
audio channels. Figure 1-8 shows the all call page source to
audio channel connections in the lower left corner. Note that all
channels receive the same signal. Any amplifier on the system,
regardless of the audio channel selected, will receive the page.
Any amplifiers that were previously idle will power up and
receive the page.
The Page to EVAC mode is used to send a page to the areas
automatically receiving the evacuation signal. Activating the
EVAC switch causes the Audio Source Unit to enter the page to
EVAC mode. In this mode, the zoned audio amplifiers connected
to the EVAC channel do not transfer to the page channel. Rather,
the Audio Source Unit redirects the page signal source to the
EVAC channel. Figure 1-8 shows the page to EVAC mode page
source to EVAC channel connections. The page and EVAC
audio channels both receive the page signal. Any amplifier
connected to either the page or EVAC audio channels will
receive the page. The alert, auxiliary and general channels are
connected to their respective signal sources, as in the normal
mode.
The Page to Alert mode is used to send a page to the areas
automatically receiving the alert signal. Activating the Alert
switch causes the Audio Source Unit to enter the page to alert
mode. In this mode, the zoned audio amplifiers connected to the
alert channel do not transfer to the page channel. Rather, the
Audio Source Unit redirects the page signal source to the alert
channel. Figure 1-8 shows the page to alert mode page source to
alert channel connections. The page and alert audio channels
both receive the page signal. Any amplifier connected to either
the page or alert audio channels will receive the page. Any
amplifiers that were previously idle will power up and receive
the page. The EVAC, auxiliary and general channels are
connected to their respective signal sources, as in the normal
mode.
The All Call Minus mode is used to send a page to all areas NOT
automatically receiving the EVAC or alert signals. In high rise
applications, all call minus is an effective way to quickly select
stairwells. Activating the All Call Minus switch causes the
Audio Source Unit to enter the all call minus mode. In this mode,
the zoned audio amplifiers connected to the auxiliary and general
channels do not transfer to the page channel. Rather, the Audio
Source Unit redirects the page signal source to the auxiliary and
four general channels. Figure 1-8 shows the all call minus mode
page source to auxiliary and general channel connections. The
