Environmental testing of outdoor fire protection electronic products

Outdoor fire-fighting electronic products should be classified according to the use environment and application site to determine the severity level of their ability to withstand the influence of various environmental tests and the safety integrity level (FSIL) they need to achieve when applied in specific situations. The outdoor fire-fighting electronic product environmental test can determine the environmental adaptability of automotive, marine, and portable fire-fighting electronic products.
Zhongke Testing Reliability Experiment Center has environmental testing capabilities for various fire-fighting electronic products, and provides professional environmental testing services for outdoor fire-fighting electronic products such as fire alarm equipment, alarm valves, and fire-fighting communication equipment.

1. Fire alarm equipment: fire alarm triggering devices, fire alarm control devices, fire alarm devices, fire linkage control equipment; etc.
2. Alarm valve: wet alarm valve, dry alarm valve, deluge alarm valve, pre-action device, delayer, hydraulic sensor, hydraulic alarm bell, etc.
3. Fire communication equipment: fire alarm dispatcher, fire command and dispatch equipment, fire vehicle dynamic management device, etc.

Operation test: high temperature (operation) test, low temperature (operation) test, constant damp heat (operation) test, alternating damp heat (operation) test, water test
Durability test: high temperature (durability) test, low temperature (durability) test, constant damp heat (durability) test, alternating damp heat (durability) test, sulfur dioxide corrosion (durability) test, salt spray test, sand dust test
