and 12/24 Volt Power

The CAMPDD24 is a multi-function surge protector for in-line coaxial
video, two twisted pairs of data and the 12 or 24 volt camera supply. The
CAMPDD24 provides multi-stage surge protection to a single camera system
and P/T/Z unit for each of these functions. The CAMPDD24 provides a heavy,
single point ground connection and is easily installed in minutes. Please read
installation instructions completely and insure good ground connections.

INSTALLATION

The CAMPDD24 must be properly installed to insure maximum protection. The function of the
CAMPDD24 is to allow a surge to be routed to ground and to clamp the protected equipment inputs
to a minimum voltage.
There are three key points to remember when installing the CAMPDD24. First, provide a low
impedance connection between the CAMPDD24 and your protected equipment. This is best done by
keeping the PROTECTED cable connections as short as possible.
Second, the system should use a single ground point. Connect the grounding stud of
the CAMPDD24 to a single ground point. A single ground point is a proper building ground or earth
ground to which equipment grounds are connected. Ideally the protected equipment should be
isolated from ground. If the CAMPDD24 and the protected equipment are both grounded you will
provide a parallel path to ground and a portion of the surge current can flow though that path.
Finally, the UNPROTECTED cables should not be crossed with the PROTECTED cables.
Crossing cables could provide a path for surge currents to bypass the CAMPDD24 protection
circuits.
