What is a surge suppressor?
A surge suppressor (sometimes optimistically called a "surge protector")
is a device inserted in the alternating current (AC) utility line and/or
telephone line to prevent damage to electronic equipment from voltage
"spikes" called transients. The power (or phone) line is effectively
short-circuited to electrical ground for transient pulses exceeding the
threshold. A more accurate term for this type of device is "transient
suppressor." Transients, which arise from various causes (not just
lightning), commonly reach peak levels of several hundred volts. The
worst type of transient occurs when lightning strikes in the vicinity.
Such a "spike" can peak at thousands of volts and cause permanent damage
to equipment. Surge suppressors should be used as a matter of habit with
all semiconductor-based electronic and computer hardware (like security
controls). * copied from www.whatis.com
When would you use
one?
With every install of a control
panel. The surge suppressor precedes the control, in the AC and/or phone
line hookup, and deflects the surge or strike to ground (and away from
the control). Note: If a surge suppressor is not grounded, it is
useless.
What makes Elk surge
suppressors different?
They respond to power surges and transients in less than 1 nanosecond,
automatically restoring after each surge within the specified ratings;
while the standard unit on the market uses MOV technology, has a
response time of less than 5 nanoseconds, and is not self restoring. Elk
units are 5 times faster and carry a Lifetime Warranty, too.
What is the
benefit?
The faster the surge is deflected to ground, the quicker it
is sent AWAY from the control, improving the odds to save the control.
The fact that it self restores, instead of "blowing" like the older MOV
technology, means longer life.
Which one will do the
job?
ELK-950 RJ Jack with Surge Suppression offers surge suppression
for the AC and one phone line, perfect for the standard security
control.
ELK-951 offers surge suppression for 1 phone line.
ELK-955 offers surge suppression for 2 phone lines.
