Functional safety SIL and fire remote Telemanagement

The technological evolution and the increasing performance requirements of detection systems and automatic fire extinguishing have introduced two new features of the fire stations: functional safety sil systems and remote management of remote systems.

Why choose functional safety SIL

The safety integrity level (SIL) is a number indicating the value of the probability that a system is running correctly an instrumental safety function within a predetermined period of time. The SIL is assigned to each safety independent  function (SIF), made by one or more Safety Instrumented Systems (SIS).

It is a number between 1 and 4, where Safety Integrity Level 4 has the highest value and the Safety Integrity Level 1 has the lowest. In practice, the SIL is a quantitative measure of the probability that a given protective function is not performed if it had required the intervention, and allows the designer to reduce the risk of a dangerous situation and quantify the reduction.
