Possibilities Concerning Diagnosis of the SSP-FK Aircraft Fire Suppression System in Terms of Determination of Reasons for False Fire Alarms / Możliwości Diagnozowania Lotniczego Systemu Przeciwpożarowego SSP-FK w Aspekcie Określania Przyczyn Fałszywego Sygnalizowania Pożaru

Electrical Disturbances in Terms of Methods to Reduce False Activation of Aerial Fire Protection Systems

“…The aim of the simulation studies of the selected electrical circuit models of the SSP-FK-BI execution blocks (developed in the Circuit-Maker computing package) was to verify the hypothesis of the possibility of their false tripping due to the influence of interference pulses occurring in the power and control circuits of the amplifier boards or the occurrence of short circuits between their internal electrical circuits [ 28 ].…”

“…To model the system response conditions from disturbances in the electrical power supply, a case was adopted [ 28 ] for investigating the possibility of false tripping of the system under conditions of a rapid drop in supply voltage. The study of the influence of temporary supply voltage drops, due to the characteristics of the US1 comparator input signal comparison channel, required additional modeling of the operation of the DPS fire sensors and DTBG, including the determination of the course of the fire signal under conditions of sudden heating of the sensor.…”
