Privacy Feature (Celebrity Screening)
Only Viking's C-2000A controller provides the celebrity screening feature for screening
out nuisance calls at the door phones. With this feature activated, a visitor must enter a
private number at the door phone before the system will ring onto the phone line.

Standard and Distinctive Ringing
The W-3000 doorbox, C-1000B and C-2000A controllers can be programmed to
provide a distinctive ring cadence to differentiate a door call from an ordinary phone
call. The distinctive ringing feature can be used with a dedicated phone, a multiple line
KSU-less phone, or household phones attached to the C-1000B and C-2000A
controllers. Since most KSU and PABX systems cannot regenerate a distinctive ring input,
this feature will not work with those systems.
Push-To-Talk
Speakerphone operation reduces vandalism commonly associated with handsets and
cords. However, in noisy environments, speakerphone circuitry has difficulty switching
between send and receive modes. The result is known as "clipping," where portions of
the conversation are lost. In these high background noise applications, your customer
needs a doorbox that can be converted to push-to-talk operation. The W-3000 self-
contained doorbox can be programmed to provide push-to-talk operation.
Distance from Phones
Many installers are asked to install doorboxes at driveway gates. These gates can be
quite a distance from the business or residence phones. In these applications you need
a doorbox with enough power to span the distance without substantial signal loss. Most
quality doorboxes allow you a distance of up to 6,300 feet.
Surface Mount and Pedestal Mount Options
All Viking flush mount doorboxes and door phones can be converted to surface mount
by using an optional VE-Series backbox. All Viking backboxes utilize heavy duty steel
construction and black powder painted techniques for vandal resistance
and long life. VE-Series backboxes will mount to standard single gang
