The Hochiki ATJ-E (HFP) detector is a multi-heat detector that is fully compatible with the Hochiki ESP analog addressable protocol.
The ATJ-E (HFP) model has the ability to operate in two modes of constant temperature and incremental temperature, which can be selected and controlled one or both simultaneously through the control panel. Detector display lights (LED) can be controlled by They also have a control panel (flashing mode)


-feature User-selectable modes

-Ability to select constant temperature mode and incremental rate temperature simultaneously

-Dual display lights (LED) with 360-degree visibility – in normal operation flashing green light, in red fire mode constant light

-Software addressing by TCH-B200 addressing tool

-Classes A, B and C approved by LPCB and Vds
