System Functions

Detailed function descriptions

ComPoint routes communications by switching
its audio bus to the keypads and door stations.
All switching takes place in the hub(s). The hub
switches the bus to either the microphone or
the amplifier in a keypad or door station, de-
pending on the direction of the communication.
For example, when you start an intercom ses-
sion, the system switches the bus to the micro-
phone in the sending keypad and the keypad
amplifier in the selected receiving zone. For the
reply, it reverses the connection so the micro-
phone in the receiving keypad is connected to
the amplifier in the sending keypad.

Communication priority levels

Certain communication events take priority over
others for proper system operation. Each func-
tion has a priority level based on its application.
If two identical levels of communication overlap,
the first to occur has priority.
System functions have the following priorities:
Door station call

Paging

Intercom

Listen mode
Thus, paging is not allowed when the audio bus
is being used for an intercom session or a door
station call. Similarly, an intercom session is not
allowed when a door call or page is in progress.
However, paging and intercom can interrupt Lis-
ten mode, and door station calls can interrupt
all other communications. DND mode blocks all
levels of communication to a zone in that mode.

Paging
Paging is the default system function. To send a
page, all one needs to do is press and hold the
Talk key and speak, as long as the keypad is
not indicating a selected zone or door station.
Since a page is a system-wide broadcast, no
zone selection is necessary.
When a page is sent, the audio bus connects to
the microphone in the sending zone and the
amplifiers in all other zones that are not in DND
mode. All keypads indicate which zone is send-
ing the page for 30 seconds after the Talk key
in the sending zone is released.
During this 30-second time frame, anyone in a
receiving zone can reply to the page by holding
in the Talk key and speaking. This switches the
audio bus to the microphone in the receiving
zone and the amplifier in the sending zone. The
reply is heard only in the sending zone.
With paging, pressing the Talk key causes a
single ping tone to sound in the receiving zones
to signal the beginning of the announcement.
Releasing the Talk key sounds a double ping to
signal the end of the announcement.
Zones in DND mode don't receive a page audio
signal but do indicate the sending zone. Also,
pages are never sent to door stations.
Intercom
Intercom is a point-to-point communication that
involves only two zones, unlike a page which is
system wide. For ease of use, the intercom
function allows hands-free replies as well as
manual replies with the Talk key.
