Chamberlain SENTEX INFINITY User Manual page 4

The Infinity systems are capable of carrying out the following
functions (several of these functions are options, so ask your
dealer which capabilities have been included in your chain):
VISITOR ENTRY
The "L," "S," "M," and "DI" series Infinity systems can store,
recall, and dial telephone numbers. It can also respond to signals
to unlock a door, open a gate, or activate any other device you
wish. A visitor is instructed to find the occupant's name on the
system directory and enter the accompanying code on the
keypad. In the "L," "S," and "M" series the directory is built into
the system and will display one page of names at a time. In the
"DI" series, the directory is typed. When the code is entered, the
system will dial the associated telephone number. The recipient
can take one of six actions by dialing a number on the telephone
(Figure 1).
NOTE: A rotary pulse dial can initiate the first action. However, all
other signals must use tone dialing.
When relay 1 is activated, the display, if the system is equipped
with one, will show "ACCESS GRANTED-PLEASE ENTER NOW"
and a short tone will be emitted. A record of each telephone entry
transaction is then sent to the printer (if the system is equipped
with one). A record of the transaction is also stored in memory.
The exact number of transactions stored depends on the firmware
and options in the system. The transaction buffer memory can be
accessed at any time to review activity.
Enable multi-entry if multiple units are sharing a phone line or if
there is just one unit. The multi-entry feature detects if the phone
line is missing or in use and displays a "LINE IS IN USE"
message.
AUTHORIZED PERSONNEL/OCCUPANT ENTRY
The system can be used by authorized personnel to control
access into a building or complex. Anyone needing access to the
complex is given either an entry code or a card. Restrictions can
be programmed for each access code and card.
ENTRY CODES
A 4 or 5-digit code is entered on either the keypad on the
system's faceplate or a remote keypad (optional). When the code
is validated by the system, access is granted. Only a limited
number of invalid codes may be entered before the system will
disable this function for 3 minutes. The rest of the system will
continue to operate.
CARDS
Cards are presented to a card reader. When the card is validated
by the system, access is granted. Each system can use up to two
card readers.
