Hochiki ATJ-EN(WHT) Addressable Heat Detector

The Hochiki ATJ-EN(WHT) is an addressable heat detector that incorporates a variable temperature heat element and a rate of rise heat element, both of which are controlled from the control panel. This allows either thermal element or both elements to be simultaneously active in making the fire decision.

This heat detector features twin LEDs which allow for 360 viewing. A green LED indicates when the detector is polling and a red LED during a fire detection state.
