TLS & LLS
TLS- Tel/ Page Line Lightning Suppressor; Very low level signal line protection.
LLS- Line Level Lightning Suppressor; Low level signal line protection.
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.
