In the past the best way to detect fire in electrical cabinets is aspirating smoke detection system. In this way, air samples of all protected cabinets are drawn back to a central detection unit using an aspirator and sampling pipe network connected to each cabinet to monitor if there’s any presence of smoke in the cabinet. Although it can detect fire in a relative early stage but the shortage is it can’t identify which cabinet is in fire. The user needs to open the cabinet one by one to search the origin of the fire.
Imagine a detection system having 60 cabinets protected by one aspirating smoke detector. When there’s alarm, the user faces rows of enclosed high voltage electrical cabinets and he needs to open and check every cabinet to find out the location of a fire. The alarm continues and the clock is ticking, the risk of explosion… how tremendous pressure is the user faced.
Now the innovative CSD cabinet smoke detector introduced by AVA PREVENT has miniature size that is especially designed for single cabinet aspirating smoke detection. The CSD cabinet smoke detector integrates aspirator, high sensitivity smoke detector, display/control/program panel, relays and network interface all together in a miniature size. It can be installed on every cabinet to detect and identify the detection and alarm status so the user will not have to perform search in a dangerous electrical fire. The CSD is a perfect solution to cabinet fire detection.
Design Planning
The CSD Detector can be installed on the top of cabinet or inside the cabinet.
When the CSD is installed on top of the cabinet, the built-in Display directly indicate the detection condition of the protected cabinet underneath.
When the CSD is installed inside of the cabinet, the Display can be removed from the detector and mounted on the cabinet panel to show the detector condition inside the cabinet.
Location of the Air Sampling Points
There should be Air Sampling Points on the Following locations where the smoke might exist in case of a fire in a cabinet . So that the fire can be detected the earliest possible.
- Exhaust Fan/Grill Sampling:When there's exhaust fan/grill for the purpose of cooling of the components inside the cabinet. There should be sampling point installed on the exhaust fan/grill for the smoke is likely to appear in this location.
- Compartment/Void Sampling:When there's separate compartment/void with fire risk inside of a cabinet, there should be a sampling point for the compartment/void.
Sampling Pipe Limitation

- Single Tube Length: Up to 12 m
- Two Branched Tube Length: Up to 2x10m
- No. of Sampling Hole: Up to 4
- Brass Sampling Hole Size: 3.5 mm
