System Sensor 2251TMB photoelectric smoke detector

• Make: System Sensor
• Model code: 2251TMB
• Type: Smoke

System Sensor 2251TMB is a photoelectric smoke detector with thermal detection. It uses advanced onboard software to combine the signals from the photo and thermal elements to create a true multi-criteria detector capable of rejecting nuisance sources, but still responding quickly to real fires. Separate photo and thermal elements also allow the detector to provide different responses to smoke or heat. In addition, the detector can adjust its sensitivity according to its environment.
