Product Summary/Installation
ISK2 Advanced Keypad (cont'd)
One of the benefits of the Advanced Keypad is
the ability to support systems as large as 36
zones, since the ISK2 is able to select any of
the zones by label. The zone and door station
labels are dynamically served from the hub and
appear in alphabetical order on the keypad dis-
play. A Page label is included in the list as the
default selection when the system is inactive
and the Talk key is pressed.
On the ISK2, the target zone for an intercom
session is selected by scrolling through the
zone list. Pressing and holding the Previous or
Next key scrolls through the list with a half-sec-
ond delay between zone labels.
A bar graph on the display indicates the zone
volume level visually in conjunction with the audi-
ble ping tones. A small pushbutton on the front
edge of the keypad is used to enter a setup
mode to assign labels to the zones.
ISK3 Door Station
Unlike the Basic and Advanced Keypads, the
ISK3 Door Station has only one key and con-
tains an internal speaker. Amplification for the
speaker is built in as with the keypads but there
is no speaker interrupt relay. A potentiometer
allows adjustment of the speaker volume level.
The ISK3 also provides contacts for closing a
standard doorbell circuit. These close for a mini-
mum of 4 seconds to activate an existing door-
bell or other device.
ISDR1 Door Strike Release Module
The optional ISDR1 Door Strike Release Module
provides relay contacts for activating a door
strike release from another manufacturer. The
module connects in the CAT-5 line between a
hub and an ISK3 door station. The ISDR1 can
be located anywhere in the CAT-5 line, though it
would be preferable to have it close to the door.

The ISDR1 obtains its operational power from
the hub. The separate door strike release must
receive voltage from its own power source.
The ISDR1 passes signals on all leads of the
CAT-5 cable except one which is used to acti-
vate the module from the hub upon receiving a
command from a keypad.
By providing a normally closed (NC) relay con-
tact in addition to the normally open (NO) and
common contacts used for the door strike
release activation, the ISDR1 can be used for
other applications where a versatile relay is
needed. The ISDR1 can be activated by provid-
ing 15 VDC between two of the eight positions
in the 110 punch-down input connector.
Keypad backlight color selection
Each ComPoint keypad can be set to either
amber or green backlighting, selected by a
miniature slide switch on the bottom edge of
one of the circuit boards.
