TLS / LLS

Tel-Page Line / Line Level Lightning Suppressor

No one knows when and where lightning will strike. But
with the inexpensive Grommes~Precision TLS/LLS, you can
rest easy in knowing that if lightning induces a surge into your
Tel-Page line, your paging amplifier will be protected!

Most lightning damage to electronic equipment is caused
through induction. With induction, lightning does not strike the
telephone line or electronic equipment directly, rather, it
propels, or induces, large voltages of electrical energy into the
system. Long telephone lines and the electronic equipment
connected to them are particularly susceptible to damage from
induction.

Therefore, Grommes~Precision designed the TLS/LLS to
prevent surges on the Tel-Page line from harming the
electronic equipment connected to it. Though few things can
withstand a rare direct strike, the TLS/LLS can help protect
electronic equipment from the much more likely induced strike.
Once the current flowing through the TLS/LLS exceeds its
switching current, the TLS/LLS clamps the transient voltage
simulating a short circuit condition. Once the current flowing
through the TLS/LLS is less than the devices holding current,
the TLS/LLS will reset, protecting your electronic equipment.

Simply connect the TLS/LLS within the Tel-Page line after
the phone system (the TLS/LLS does not pass telephone
ringer voltage) and directly before the electronic equipment
you wish to protect.

And, with over a half-century of experience in the business,
Grommes~Precision’s TLS/LLS is made in America, and is
backed by Grommes~Precision’s unbeatable expertise and
Assurance Policy: a 5 year warranty and 30 Day Money

Back Guarantee.
