POSTAL LOCK/REQUEST FOR ACCESS/
DOOR POSITION MONITORING
Test these features by shorting across the appropriate terminal
block pins, then check to make sure the associated relays activate
and deactivate properly.
Once your wiring is in place, test the functions again.
BUILT-IN MODEM
Call the system using a Hayes-compatible modem hooked to a
terminal (or PC using terminal emulation software).
If connection is made, the "TRANSMIT MODEM DATA" and
"RECEIVE MODEM DATA" indicators should flash as data is
transmitted and received, and you should be able to access the
programming mode described in Section 10 of the programming
manual.
If connection is not made, ensure the baud rates of both modems
match. For an 1100329 board, the baud rate must be set to 300,
1200, or 2400 baud to communicate with the system's 300 (or
2400) baud modem.
MULTIPLE ENTRY
Disconnect the telephone line from the system and try dialing a
number. If the system displays a "LINE IN USE - PLEASE WAIT"
message, this feature is working correctly.
Reconnect the telephone line and the system should beep and
display the message "LINE IS NOW AVAILABLE - PRESS # TO
TRY TO CALL AGAIN." Make a call or press the "S" button until
the welcome message returns.
METHOD OF DIALING
The system is factory set to use DTMF tone dialing. To change to
rotary (also called pulse) dialing, enter the programming mode
(see programming manual) and press "55" followed by "ENTER."
When the new programming prompt appears on the screen, the
change has been made. To change the method back to DTMF
tones, use the same procedure except substitute "60" for "55."
OPTIONAL CLOSED CIRCUIT TELEVISION (CCTV)
MONITORING
When the monitor or television is turned on, picture will appear. If
no picture appears, check the J1 connector on the CCTV power
supply board (Figure 9).
A. Make sure the connector is firmly attached to the
power supply board.
B. The connector is keyed and must be attached in the correct
direction. From left to right, the wires should be: yellow (video);
blue (ground); and red (power).
