Reliable, high-performance fire detection without nuisance alarms or premature deluge activation is a requirement in NFPA 33 automotive paint line applications. The X3301 Multispectrum Infrared Flame Detector, when equipped with our unique dual-stage automotive mode and combined with the Eagle Quantum Premier® (EQP) Safety System Controller, delivers the level of detection/protection needed for this application as defined by NFPA 33.
The current requirement in fire/loss prevention for automotive paint lines is to use independent alarm action to initiate a two-stage extinguishing process. In the first stage of this extinguishing process, the painting operation is shut down. Sometimes, this action is combined with the discharge of a gaseous suppression agent. If this first action does not successfully extinguish the fire, the second stage of suppression, typically water deluge, is initiated.
The dual-stage response is designed to minimize process interruption in case of a fire. If the first stage extinguishes the fire, use of a water deluge is eliminated, minimizing downtime and loss. If the first stage of action fails to extinguish the fire, the second stage of action (water deluge) is executed to prevent catastrophic damage and loss.
The X3301 automotive mode meets these requirements by providing independent outputs to activate these two stages of mitigation. This important feature helps minimize the losses associated with the consequences of executing an extinguishing event when it is unnecessary.
