This Surge Protection Device (SPD) is a high performance device, designed to provide protection
for sensitive electronic loads connected to service panels, fire panels, or where the SPD is
directly connected to the electronic device. Maximum protection will only be achieved if the SPD
is properly installed. Please read and follow the installation instructions carefully.
NOTICE: This SPD should be installed and grounded, by a licensed contractor, per the applicable
requirements of the NEC. These devices are only to be employed on the communication loop circuits
which have been isolated from the Public Switched Telephone Network.
APPLICATION
Surge suppression for CCTV circuits using a BNC to BNC connection.
This device is intended for indoor use or intended for outdoor use within an enclosure which has been
evaluated for the application.
WIRING INSTRUCTIONS:
Caution
unit. Improper installation voids the warranty.
Pre Install Actions:
This unit must be connected in series with the field wiring and the equipment to be protected.
1. Check the video signal before installation to verify correct operation.
2. Power down and disconnect the circuit this device will connect to before beginning installation.
3. Disconnect the video cable feeds from the DVR.
4. Securely mount this unit between the field wiring and the equipment to be protected. Use double
sided tape or four #8 screws.
Video Protection:
1. Connect the unprotected video cables from the cameras to the DTK-4VP’s IN/UNPROTECTED
side.
2. Connect a 3’ factory terminated BNC to BNC patch cord from the DTK-4VP‘s
OUT/PROTECTED side to the DVR’s video input.
Ground Connection:
Connect a minimum #14 AWG wire from the ground connector to the common earth ground. Always
have one common ground per system to eliminate the possibility of a differential in ground potentials.
Ground Resistance Rule:
Max ground resistance is 25 Ohms, 5 Ohms or less is optimum.
This cannot be an assumed value and must be measured to assure proper grounding.
Post Install Actions:
After all connections have been made and no hazards exist, restore power.
Check the video signal after installation to ensure proper install and no signal distortion.
