Application Note

October 8, 2003

Initiate Dialing from a Contact Closure

All of Viking’s Hot-Line dialers, both exisiting 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 closure, allowing the dialer to dial a
phone number or pager number for alarm notification.

Various contact closures are
required depending on the
dialer.

A. Converting the K-1900-5 to Contact Closure Dialing

Important: Electronic components are sensitive to static electricity. Personnel and the work area

should be grounded before handling.

1. Remove the cover of the K-1900-5 with your hands.

2. Locate JP1.

Note: There are (2) two pin headers on the circuit board. Use the diagram (right) to find JP1.

3. Short the two pins on JP1 together. Wrapping a bare telephone wire around both pins is suggested.

4. When finished, replace the cover.

Important: Be sure whatever is used to short the jumper is not touching any other components.

B. Installation

Note: The K-1900-5 will drop the line as

soon as it is 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.
