Abstract

Telephone and/or telematic equipment protection system. The system is based on protection modules 3 fitted with a gas spark gap 7, a voltage limiter 9 and a pair of components in series 10 that create a potential difference between the stages precisely determined by this spark gap 7 and limiter 9, to cause its ignition. The innovation consists of including, in series with the limiter 9, a fuse 11 that blows as a result of a specified current disturbance, leaving an open circuit, a circumstance that is detected by an alarm module 4, via a control pair, this module 4 including a relay type device 14 that energizes the alarm 15. The purpose of the system is to give warning when the corresponding protection module 3 has suffered a disturbance such that, although continuing to operate, the risk of this protection ceasing to function after the next activation is very high.
