2.2 DESCRIPTION
The Model 542 and 543 are primary surge protectors for CCTV
and SATV/CATV security systems with coax cabling. To offer extra
protection against damaging transient surges, the Model 542 and 543
utilize a “two point” approach: for each CCTV line, one Model 542
protects the building entrance/exit while a second Model 542 protects
each remote camera location. The Model 543 works similarly for
SATV/CATV lines. Both the Model 542 and 543, with bandwidths of 80
MHz each, clamp surge voltages at 12 volts and have response times
of 0.2 μsecs. The Model 542/543 offers two circuits for surge
protection, the Primary and the Secondary:
Primary: The Primary circuitry consists of the “quick response”
circuitry that protects the data from normal surges that fall into the IEC
801.2, 801.4, and 801.5 categories. The protection is between the data
line and the shield ground. The Primary can handle 400A with an
8/20μs wave form. Refer to Appendix A for the specifications.
Secondary: The Secondary circuitry contains powerful surge
protection devices that are slower, but can handle larger currents than
the faster response SAD. This protection is parallel to the primary
protection and between the shield ground and the frame ground (braid
connection). The Secondary can handle 20kA with an 8/20μs wave
form. Refer to Appendix A for the specifications.
3.0 INSTALLATION
The Patton Model 542 and 543 are easy to install. The following
instructions will clearly explain each step:
1. Unplug the existing connection between the coaxial cable and the
CCTV equipment's BNC port for the 542, or the SATV/CATV
equipment’s F-Series port for the 543.
2. Install the Model 542 or 543 between the incoming coax line and
the protected equipment (see below). Place the surge protector as
close as possible to the device being protected.
3. Connect the braided grounding strap directly to an earth ground
connection on or near the protected device. If you are not sure
where to locate an earth ground connection, consult the
equipment's user manual or contact the manufacturer. This ground
connection is critical for proper operation of the Model 542 or 543.

APPENDIX B
INTERNATIONAL ELECTROTECHNICAL COMMISSION (IEC)
COMPLIANCE
Meets IEC standards 801.2, 801.4 and 801.5 (CE Mark)
Effective January 1996 the European Economic Community will
require that all electronic devices be tested and comply with all
applicable International standards relating to the product type and
category of use. Electromagetic Compatibility Directive 89/336/EEC
specifically addresses communication line surge protection devices,
since conformity to immunity standard EN50082-1:1992 is mandatory.
The EN50082-1:10992 standard incorporates International
Organization for Standardization (ISO) publications 801.2 and 801.4,
which describe Electrostatic Discharge and Electrical Fast Transient
requirements. ISO 801.5 describes Surge Immunity Requirements and
is expected to be adopted as a mandatory requirement under
EN50082-1 by the Technical Committee in 1996. Any protector sold
into the international community must meet these standards. This
device has been tested and found to comply with these standards as
evidenced by its CE mark
