Non coding smoke common causes of failure alarm system which

Non coding smoke detector can be compared with the traditional fire alarm host networking, in actual use, the alarm system there are false positives, false negatives, delay alarm fault, the fault has the following several reasons.

Non coding smoke detector quality problems

Currently on the market of automatic fire alarm products of various manufacturers, product quality uneven, some products of the technical indicators are not up to the requirements for the use of the environment, non fire factors (temperature and humidity, dust etc.) sensitivity drift caused by not automatic compensation or compensation capacity is low, influence on the electric spark, strong electromagnetic field, high speed flow etc. various interference is not automatic processing and lead to false positives, such false positives in the traditional automatic fire alarm system in a more prominent.

Non coding smoke detector model selection or the installation position is not reasonable

The first non sensitivity encoding smoke detector sensitivity is unreasonable, the degree of sensitivity of fire parameters such as fire detector, detector installation environment normal fire parameters close to or at the detector response range, it will cause the fire alarm fire belongs to the non parameter; second is the use of site selection detector type improper or use place changes not considered the fire detector type change, make the conversion circuit detector failure cause false alarm of fire.

Non coding smoke detector installation environment factors

There is a common environmental impact is the effect of electromagnetic environment on the smoke detector, the main air electromagnetic wave interference, power supply and other input and output lines on the narrow vein, electrostatic; air speed, environment visibility.

Non coding smoke detectors installed improper construction

For example, when construction for dust control; system ungrounded or grounded not up to standard requirements, make the system vulnerable to electromagnetic interference, resulting in false alarm; line insulation is not up to the requirements, the joint line is bad or wiring unreasonable; on the detectors, moisture-proof, dustproof anticorrosive measures improper handling.
