a. Visitor Initiated Call
Adoorbox may be monitored from any phone connected to the C-1000A by Touch Tone dialing a “#” followed by
a Touch Tone “1” or “2” to monitor doorbox 1 or doorbox 2 respectively. This feature is not available for pulse
dialing phones. Note: Do not attempt doorbox monitoring while a call is in progress, the call will be discon-
nected.
Note: When monitoring, the auxiliary contact will only work on the Continuous Mode (11).
b. Monitoring Doorboxes
Entering these codes while in programming will switch the C-1000A into the corresponding mode.
Disable Special Modes (✱0): This command disables (clears) all the special modes listed below. Enter this command
before programming the rest of the selections to be sure no unwanted modes are set.
Doorbell Mode (✱1): In this mode, the ring signal from either doorbox is prevented from going through to the
“PHONES” port. This is useful when a conventional door bell is connected to the auxiliary contacts. Now when some-
one activates a doorbox, the doorbell will chime rather than the phone ringing (see Programming section B).
Custom Ring Mode (✱2): With this mode selected, the ring signal from the device ports are interrupted in a double
burst pattern, making it easier to determine if the incoming call is from a doorbox or the C.O. line.
Multiple Relay Activation Mode (✱3): If selected, after a door strike command is entered, the phone is switched back
to the doorbox port so additional doorstrike (relay activation) commands can be entered. This is useful when letting
someone through your gate with the first command then unlocking your front doorstrike with a second command. To
return to the call on hold, enter “#”.
Paging Mode (✱4): In this mode a paging system that provides talk battery (Viking PA-2Aor CPA-7B) can be con-
nected to one of the doorbox ports. When the person on the phone wants to make a page, they can enter “#” and a “1”
or “2” depending on which port the paging amplifier is on. After the announcement is made another “#” will return them
to the phone conversation.
Inhibit Latching Commands Mode (✱6): In some installations it is critical that the door strike or door actuator not be
turned on for long periods of time. To prevent this from happening, enter ✱6when in programming. In this mode, the
toggle command (✱#) and the continuous activation command (✱1) are ignored.
