The Hochiki ATJ-EN(WHT) is an analogue Heat Detector which incorporates a variable temperature heat element and a rate of rise heat element. Both of the elements are controlled from the control panel, allowing either thermal element or both elements simultaneously to be active in making the fire decision. The sensor polling LEDs can also be controlled via the Control Panel (pulsing/non-pulsing).
