You need to know that with the evolution of electronics, the capacity of devices increases and their size decreases. That is why the service life between old and new models may be different, like any other electronic device. For new systems, the service life is about 5 years. For older systems, the service life can vary between 7 and 12 years. However, we recommend that you update your alarm system after 5 years and that you stay informed of technological developments of your system.
