The time required to complete fire generally include fire detection time, probe delay time after the fire to cast gas before the gas discharge suppression time time and gas, and the like. If the pressure resistance and fire resistance of a building element of a protected area of ??less than the above time requirements, there may not yet fully extinguished before the fire was destroyed by fire and bad stress, the closure of the protected area is damaged, causing gas resulting in a huge loss of extinguishing agent fire failed and resurgence.
