The ATJ-EN(WHT) features a variable temperature heat element and a rate-of-rise heat element, both configurable via the control panel. Either element, or both simultaneously, can be active when detecting a fire. The sensor’s polling LEDs can also be controlled from the control panel (pulsing/non-pulsing).
