Product Description
. . . . . Intelligent thermal detector with rate-of-rise feature
Johnson Controls 5951J Series intelligent plug-in thermal detectors with integral communication has features that surpass conventional detectors. Point ID capability allows each detector's address to be set with decade address switches, providing exact detector locations. 5951J Series thermal detectors use an innovative thermistor sensing circuit to produce 135°F/57°C fixed-temperature (5951J) and rate-of-rise thermal detection (5951RJ) in a low-profile package. 5951HJ provides fixed high-temperature detection at 190°F/88°C. These thermal detectors provide effective, intelligent property protection in a variety of applications. 5951J Series detectors are compatible with the Johnson Controls Intelligent Fire Alarm Control Panels (FACPs). FlashScan® (U.S. Patent 5,539,389) is a communication protocol that greatly enhances the speed of communication between analog intelligent devices. Intelligent devices communicate in a grouped fashion. If one of the devices within the group has new information, the panel's CPU stops the group poll and concentrates on single points. The net effect is response speed greater than five times that of earlier designs.. Johnson Controls. Johnson Controls. 5951RJ.
