Door Station Call - Russound COMPOINT SYSTEM Instruction Manual

Intercom (cont'd)
The intercom function requires first selecting a
target zone. This is done by pressing a zone
key on the ISK1 Basic Keypad or scrolling to a
zone label on the ISK2 Advanced Keypad. After
selecting a zone, the user may press the Talk
key to begin communication.
If an invalid zone (one that has no keypad) is
selected on an ISK1 Basic Keypad, the zone
key blinks rapidly for 7 seconds. Pressing
another zone key selects another zone. After a
valid target zone is selected, pressing the same
zone key deselects it.
If a zone in DND mode is selected on an ISK1
Basic Keypad, the zone key and DND key blink
rapidly for 7 seconds when the Talk key is
pressed.
With the ISK2 Advanced Keypad, only valid
zones (ones with keypads connected) appear in
the zone list on the display. If a zone in DND
mode is selected, the display alternately shows
the zone label and DND at 1-second intervals
and the DND key blinks rapidly for 7 seconds. A
selected zone can be deselected by selecting
Page or another zone.
When receiving an intercom message, the tar-
get keypad indicates the sending zone. This
indication remains for a 37-second reply period
after the Talk key on the sending keypad is
released.
There are two ways to reply to an intercom
message with either type of keypad: a hands-
free reply within 7 seconds and using the Talk
key within 30 seconds thereafter. When the Talk
key on the sending keypad is released, both the
sending and target keypads sound a single ping
INSTALLER SECTION
and the target keypad permits a hands-free
reply by activating its microphone for 7 sec-
onds. During this period the Talk key on the tar-
get keypad is lit red to indicate the microphone
is active.
After the 7 seconds, a double ping in both the
sending and target zones indicates the end of
the hands-free reply period. A reply may still be
made by pressing and holding the Talk key with-
in the next 30 seconds. After the 30 seconds, a
reply can no longer be made, but a person in
the receiving zone can start a new intercom
session to the original sender.
Each time a Talk key in either zone is released,
a single ping is heard in the other zone and the
7- and 30-second reply periods are renewed.

Door station call

Communication with the door stations is similar
to an intercom session, though there are signifi-
cant differences. First, a door station has no
ability to select a target zone. Instead, it simply
rings the doorbell and a person in any zone can
reply. Second, for privacy reasons the system
doesn't allow a hands-free reply to a door sta-
tion call from the interior keypads. The reply
can be made only by pressing and holding the
Talk key.
When the Call key on a door station is pressed,
each hub instructs all connected keypads that
aren't in DND mode to activate their speaker
relays and connects the audio bus to their
amplifiers. If a doorbell chime is selected on
hub 1, the chime is played through the speaker
outputs on those keypads and through the inter-
nal speakers in the door stations.
