The 2951TMJ Acclimate detector is an intelligent, addressable, multi-sensing, low-profile detector designed for use with the Johnson Controls IFC-400 and IFC-1010/-2020 (classic mode only); and with the IFC-640, IFC2-640, IFC-3030 and IFC2-3030 (classic or FlashScan modes) Fire Alarm Control Panels. The Acclimate detector uses a combination of photoelectric and thermal sensing technologies that are designed to increase immunity to false alarms. Unlike traditional intelligent detectors, the Acclimate detector has a microprocessor in the detector head that processes alarm data. As a result, the Acclimate detector adjusts its sensitivity automatically, without needing operator intervention or control panel programming. Areas where the Acclimate detector is especially useful include office complexes, schools, college campuses, manufacturing and industrial facilities, and anywhere else the use of a particular area may change. The Acclimate detector automatically adjusts its sensitivity to the environment.
