The All Call mode is used to send a page to the entire facility. When the All Call
switch is activated, the EAEC is put into the all call mode. In this mode, the
zoned audio amplifiers do not all transfer to the page channel. Rather, the EAEC
redirects the page signal source to all the audio channels. Figure 16 on page 86
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 EAEC 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
EAEC redirects the page signal source to the EVAC channel. Figure 16 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 the 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 EAEC 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 EAEC redirects the
page signal source to the alert channel. Figure 16 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. Pressing the All Call Minus button
causes the EAEC 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 EAEC redirects the page signal source to the auxiliary
and four general channels. Figure 16 shows the all call minus mode page source
to auxiliary and general channel connections. The page, auxiliary and four
general audio channels all receive the page signal. Any amplifier connected to
the page, auxiliary or general audio channels will receive the page. The EVAC
and alert channels are connected to their respective signal sources, as in the
normal mode.
