The same detector showed the sensitivity value of 3.2%/m by the filter paper of the Japanese standard. E-PD, E-PHD, and E-PDD detectors offer a variety of sensitivity settings. Detector sensitivity can be programmed in the control panel software. This threshold is at a sensitivity level Heat detector alarms at 57 C (135 F) ambient. NFPA 72-2016 14.4.3.2-17 (h)(4) states that "Smoke detector/control unit arrangement whereby the detector causes a signal at the control unit when its sensitivity is outside it listed sensitivity range" is an acceptable means of ensuring that each smoke detector is within its required sensitivity range. ing, smoldering fires, the SC30U-3 photoelectric smoke detector, provides reliable sensing for conventional fire alarm applications. Since the sudden and total obscuration of the light beam is not a typical smoke signature, the detector sees this as a trouble condition, not an alarm. (3) Listed control equipment arranged for the purpose. Those code references give detailed information on the schedule (1 year after installation, alternating years after that) and method of sensitivity testing. Smoke detectors that have adjustable sensitivity ranges can be corrected as needed. The detector's on-board microprocessor measures and analyzes these signals. When the detector senses smoke goes into pre-alarm sensitivity the LEDs will .
