RF SPD TESTER: radiofrequency test device for data & communication lines surge protectors

Check the status of the ATFONO, ATLINE and ATVOLT SPD series without using electrical contacts and with a simple click.

RF SPD TESTER is a radiofrequency portable device for checking the pluggable modules status of our SPD series ATFONO (data lines), ATLINE (telephone lines) and ATVOLT (DC power supply lines).

How it Works:

Pressing the test button, the RF SPD TESTER sends out a signal to the receptor of the surge protector. If the protector’s LED flickers green, then the module is working properly. When the LED does not flick, the module is damaged and it must be replaced as soon as possible to avoid imminent failure and thus system downtime.


  • Easy and fast test: it is only necessary to bring the RF SPD TESTER to the pluggable module and press the test button.
  • No electrical contacts.
  • No need to remove the pluggable module during the test operation.
