All of Viking’s hot-line dialers, both existing and discontinued, may
be configured to dial when triggered by a contact closure. This is
ideal for applications where a piece of equipment provides the clo-
sure, allowing the dialer to dial a phone number or pager number for alarm notification.
Various contact closures are required,
depending on the dialer.
Important: Different revisions of products
may require different programming and/or
setup. Please read your serial label to find
the proper selection.

A. Converting the K-1900-5 to Contact Closure Dialing
Note: The K-1900-5 will drop the line as soon as
it’s done dialing, so it is important to add several
pauses to the end of the dialing string to allow
time for the call to go through. If the contact or
switch is continuous, the K-1900-5 will drop the
line when closure is released.
