Hochiki ATJ-EN(SCI) Analogue Multi-Heat Sensor with SCI

Hochiki ATJ-EN(SCI) Analogue Multi-Heat Sensor with SCI

The ATJ-EN(SCI) is a Multi-Heat Sensor with SCI, which is fully compatible with Hochiki’s ESP Analogue Addressable Protocol.

The ATJ-EN(SCI) 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).
