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.
