Replacement probe module for 3-module flush-mounted LPG gas detectors for Perry 1GA43917.

Replacing the probe module with the similar spare module allows an extension of the life of the fixed power supply/relay module by another 5 years, allowing savings on the costs of purchasing and installing an entire detector and a lower environmental impact due to the recycling of electrical products at the end of their life.

After another 5 years of operation (continuous use), the appliance signals the necessary replacement of the entire product.
