Multi-Criteria Sensors
MRI-2251TMB Smoke & Heat Detector
MRI-2 251TMB Smoke & Heat Detectors are an photoelectric smoke detector with supplementary 135°F thermal and also known as Acclimate™, it uses advanced on-board software to combine the signals from the photo and thermal elements
MRI-2251TMB Smoke & Heat Detectors are Secutron's intelligent low profile addressable plug-in photoelectric smoke and heat detectors. It is a true multicriteria detector capable of rejecting nuisance sources, but still responding quickly to real fires. Acclimate has the capability of adjusting its sensitivity according to the type of environment that it is installed in. its integral communications provide features that surpass conventional detectors. Sensitivity is continuously monitored and reported to the panel where the desired detector sensitivity can be programmed. Point ID capability allows each detector’s address to be set with decade address switches, providing exact detector locations for selective maintenance when chamber contamination reaches an unacceptable level
