VESDA smoke detection systems are well suited for usage in food plants since the highly effective smoke detection units can be installed in protected spots. This ensures that the smoke detection units will not be exposed to the abnormal low temperatures normally associated with the freezing cold conditions in food plants. With the VESDA smoke detection units it is thus possible to extend the fire alarm network to areas which would otherwise be difficult to monitor. IDtek has experience in the installation and maintenance of VESDA smoke detection units in large food processing plants, where the units continue to operate effectively even under extreme cold conditions. The system also provides for a complete audit trail of problems identified over an extended period, enabling planning to prevent such occurrences of happening again in the specific areas of the food plant.
