With the increase of the operational resource, the fire conditions in the power and auxiliary facilities increased. One of the reasons is aging of the insulation of power and auxiliary equipment. Expired operational resource does not allow to keep the fire detection system of the locomotive in good condition. That is why the thermal assemblies with thermal sensors have been replaced on the 44-108 series of locomotives, and additional temperature sensors have been installed in the areas with high risk of fire. These are in rectifying units, battery cabinets, as well as in the air ducts of horizontal fans.

The implemented conventional fire detection system of the 44-108 series is a 16-zone with two relay outputs. It works in parallel with the existing fire alarm locomotive system. Its saving of occurrences of fires, fast-acting signaling allow to reduce response time. This reduces the risk of fire and, in case of occurrence, specifies the location of the fire. The collected data from the Temperature Zone Enhancement Plant allows analysis and precautions to be taken to prevent the occurrence of a fire. The implemented system also allows fire extinguishers to be controlled. It is affordable and inexpensive for servicing and maintenance by locomotive staff. The latter is of particular importance, given the expired operating life of the 40-00 series of locomotives.
