The Simplex® 4004R is a two-hazard releasing system that incorporates big-panel features into a small and cost-effective package. Its dual hazards can be programmed to provide an agent release for one hazard and preaction or deluge for another hazard providing the ultimate in a fire protection system. With the early detection capability of the agent release hazard, the fire should be extinguished before the preaction or deluge system is activated. A 50-point historical log allows you to investigate the cause of a release after the event.
