HOCHIKI Analogue Heat Fire Alarm Detector Sensor Model ESP System ATJ-EN(WHT)

The ATJ-EN incorporates a variable temperature heat element and a rate of rise heat element, both of which 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).
