2.2 DESCRIPTION

The Patton Model 550 Series of high speed data line surge

protectors complies with UL specification 497A for secondary surge
protection. Each protector in the series can handle 3.8 Kilovolts of
transient voltage spikes (1.2/50µS), and can withstand an AC power
fault of 600 volts. The Model 550 series is UL497A listed as a
secondary protector; the series provides full protection against AC
power crosses.

The Model 550 Series includes four models, each tailored to a
different type of data circuit: The Model 550-LL2 protects 2-wire

dial-up

telco

circuits. The Model 550-LL4 guards 4-wire

leased telco

lines.

The Model 550-DDS protects 4-wire

DDS

circuits. The Model 550-T1
guards 4-wireT1lines. All models in the 550 Series employ a solid
state combination of varistors, resistors and fuses to achieve the quick
response time needed to handle high-speed transients, plus the
"muscle" to withstand AC power faults.

Each Model 550 Series protector is equipped with a heavy duty
braided metal strap to shunt harmful overvoltages safely to ground.
Housed in a sturdy, flame retardant plastic case (UL94-5V flame rating),
all Model 550 Series units connect in-line to data comm equipment via
RJ-45 modular interface. The Patton Model 550 Series is
manufactured in the USA.

Warning—Should your equipment or building be subject to a direct
lightening strike, this product will not provide complete protection.
